Bypass

Frequently Asked Questions

Q What is the proposed location of the bypass?
A As of December 2016 by Canon Consulting Engineers

To the east of Long Stratton as shown on the plan. The bypass will start at the north of Long Stratton to the south of the existing Church Lane junction before following a line to the east and south to reconnect with the A140 approximately 1200m south of the (southern edge) of the village.

 

Q How long will it take to build?
A As of 1st December 2016 by Canon Consulting Engineers

The build programme for a road of this scale would be in the order of 18 months. However, the bypass will potentially be delivered in phases linked to the delivery of development. The phases of the bypass will be linked to acceptable impacts of development before a bypass is considered necessary balanced with the viability and business case supporting the development funds to deliver the bypass.

 

Q Will the building of a bypass create a lot of ‘works traffic’ and ‘hold ups’ on an already busy and slow road?
A As of 1st December 2016 by Canon Consulting Engineers

The bypass will create construction traffic movements. The impact of these will be managed by a construction management plan. How the bypass is delivered can help control the impact of vehicles on Long Stratton. This could include the amount of traffic in the morning and evening peak periods when existing problems in the village occur. It is also likely that some routes to/from the bypass will be restricted, such as Hall Lane for instance. The location of the construction site and its access will be important in controlling the construction vehicle impacts on the village.

 

Q Who is paying for the bypass? Will we have to pay more council tax?
A As of 5th April 2017 by Mike Haslam Planning and Development Consultant

A proportion of the costs of the new bypass will be met by the developer but additional funding will be required and this will come from the Community Infrastructure Levy and, possibly, the Local Growth Deal.

 

Q How much traffic will use the bypass?
A As of 1st December 2016 by Canon Consulting Engineers

To the north of Long Stratton some 20-21,000 vehicles use the A140 on a daily basis. To the south some 18,000 vehicles use the A140. Of the existing traffic in Long Stratton in the peak hours it is considered that some 70% to 85% would divert to the bypass. The bypass will therefore remove some 12,000 to 18,000 vehicles per day. The traffic remaining in the village will be that associated with local journeys to schools, shops and employment, such as South Norfolk Council and the Tharston Industrial area.

 

Q If a large percentage of the A140 traffic is going to use the new bypass that will reduce the numbers of opportune customers to my shop. What are you going to do about the loss of trade I may suffer??
A As of 1st December 2016 by Canon Consulting Engineers and Cornerstone Planning Ltd

The through trips on the A140 are not necessarily using local facilities on a regular basis, not least due to the delays in Long Stratton. A positive benefit of the delivery of 1,800 dwellings and a bypass will be the increased population in Long Stratton of around 4,500 residents who will support the local services. The removal of through traffic will make the village centre more attractive and more accessible to local residents, and the impact of loss of through-trade is therefore expected to be transient. The AAP includes proposals to undertake ‘post bypass’ enhancement works to the town centre, improving its viability and vitality. The EIA supporting the applications will include a socio-economic chapter, which will address these and related issues in more detail.

 

Q If there is a bypass does this mean we won’t have all the heavy lorries coming through the village?
A As of 1st December 2016 by Canon Consulting Engineers

There will be fewer lorries with the bypass, than without it. Along with the through traffic that is removed there will be a significant volume of lorries removed at the same time. However, there will be some lorries present in the centre of Long Stratton and on the immediate approaches to the village to access shops and commercial properties, such as at Tharston Industrial Estate. The configuration of access junctions to the bypass, particularly at the new Southern Gateway, will allow for revised lorry routing in the village, particularly away from the High Street and Hall Lane for example. Such traffic management measures will be a feature of the overall Transport Strategy developed as part of the planning application and able to be implemented by the Authorities to lock in the benefits of the bypass.

 

Q What will be the speed limit on the bypass?
A As of 1st December 2016 by Canon Consulting Engineers

It is NCC’s requirement that the A140 as a strategic road in the County should be designed and operate
at 60mph. The Development Team has identified constraints where a lower 50mph operating speed would improve the environmental impacts of the bypass and have suggested a mix of 60mph and 50mph sections of the bypass. It is noted that throughout its length the A140, have a mixture of 30, 40, 50 and 60mph speed limits. Current evidence shows the average speeds recorded at survey sites showed for those in a 50mph limit the average speed was 43mph and in 60mph limits it was 46mph. As such there is difference between the speed limit and the actual speeds being achieved on average.

The impact of the speed limit on journey time and the attractiveness of the bypass to divert through traffic is considered negligible. This is a topic of debate between the Authorities and Development Team and a conclusion is expected to be reached shortly.

 

Q Will the bypass create more noise?
A As of 29th March 2017 by Cornerstone planning

Traffic on the bypass will of course generate noise but the objective of a comprehensive approach to planning and design is that such noise will be managed and the affected properties will be assessed to minimise and to limit to beneath guidance levels. Currently, whilst traffic speed is low through Long Stratton the traffic noise impact on immediate residents is high, albeit when you are set back behind other properties the noise reduces. Noise on the bypass is primarily a function of the volume of traffic and the speed at which it travels. The impact of noise is dependent on how the road is designed within the landscape.

It is necessary for the development areas contained within the bypass that noise limits are controlled and this will require mitigation. Part of the mitigation will be provided by landscaped features such as bunds. Part of the mitigation can be controlled by deciding to limit vehicle speeds, through a speed limit. The Development Team has suggested a landscape led approach to the bypass design rather than a hard engineered approach. This rationale relates to the objective of protecting landscape designations to the east of Long Stratton, to creating an attractive living environment, and visually pleasing/sensitive gateways to the village of Long Stratton. For this reason an approach that limits the impact of noise mitigation to a height of 2m and sets back the development accordingly will create a more attractive living environment and setting to both the development, the new edge of Long Stratton and the road itself.

 

Q Will having a bypass mean less air and noise pollution in the village?
A As of 29th March 2017 by Cornerstone planning

Yes. Removing through-traffic from the town centre will lead to improvements to the noise and air quality environments. Detailed assessments relating to noise and air quality will form part of the Environmental Impact Assessment work that will inform and accompany the planning applications. These will assess the current situation and predict that which will arise from the proposed development of the bypass and associated development.

 

Q Is Hempnall Crossroads part of the bypass?
A As of 1st December 2016 by Canon Consulting Engineers

Hempnall Crossroads was part of the original bypass scheme proposed by NCC in 2005. The bypass at that time reconnected with the A140 at the Hempnall Crossroads and was a new roundabout junction. The overall scheme for a bypass in Long Stratton endorsed in the JCS includes for improvement to Hempnall Crossroads as a standalone scheme. The form of improvement is subject to option testing by the Authorities and Development Team.

 

Q How will I get out of the village, won’t I simply have to queue like now?
A As of 1st December 2016 by Canon Consulting Engineers

The design of junctions that reconnect the bypass with the A140 will provide capacity to allow traffic to access the A140 north and south. Other opportunities to access the bypass are also being created for both existing village connections, such as at Hall Lane and Church Lane, but also for the new development such as at the Southern Gateway and possible Northern Gateway. The Northern Gateway is subject of debate with the Local Authorities currently and resolution as to whether it is necessary or acceptable to them is expected shortly.

 

Q Won’t the 1,800 houses simply replace the traffic that the bypass removes?
A As of 1st December 2016 by Canon Consulting Engineers

No, there will be some traffic generated by the development that will use the village, but the principle behind a bypass with access to the development areas to the east is so that much of the traffic from development to external destinations north and south of the village does not need to travel through the village. A bypass without junctions but with development would impact more on the village than a bypass with junctions. The question remains how many junctions is acceptable or suitable to deliver this positive management of development traffic.

 

Q I walk my dog on Edges Lane, where will I walk in the future?
A As of 29th March 2017 by Cornerstone planning
The construction of the bypass will result in the severance of some through-routes to the east, including Edges Lane. However, the masterplanning of the development seeks to maintain existing rights of way and ‘green infrastructure’ provided this can be done safely. The new development will make provision for significant new areas of green space, throughout both the eastern and western parts of the scheme. These will provide for a range of formal and informal recreation, including dog walking.

 

Q I live on Hall Lane, there is a junction with the bypass and all traffic will access the village this way. Why do we need a junction?
A As of 1st December 2016 by Canon Consulting Engineers

Hall Lane is an important route to/from the east of Long Stratton to the A140. Traffic from the east will no longer have to go into Long Stratton to access the A140 if a junction is provided in this location. However, some traffic from the existing village to the west of the High Street will have a more direct route to the bypass via Hall Lane as will some traffic from the development into Long Stratton. There is furthermore provision in the AAP for an intended link between the new development and The Street, ideally in a location of near Flowerpot Lane. A road can be taken up to the rear to the Stratton Motor Company for example, should that become redeveloped and accommodates.

 

Q Will the bypass be built first?
A As of 16th March 2017 by Canon Consulting Engineers

No. It is not financially viable for the development to fund its share of the bypass until quite a lot of new homes have been sold to create sufficient revenue. It will however be built as soon as it can. It may be that in partnership with the local authorities it can be achieved for a way of bringing that forward as soon as possible. (say whereby a larger share can come from the public purse and be reimbursed as dwelling build and
sales progress).

 

Q Will the bypass be able to be upgraded to a dual carriageway in the future?
A As of 21st April 2017 by Mike Haslam Planning and Development Consultant

This is not in policy or consideration. However it might be considered easier to dual than most because it will not have any direct access.

 

Q Will there be any foot bridges connecting to the other side?
A As of 16th March 2017 by Canon Consulting Engineers

When the NCC scheme was progressed as a dual carriageway road in isolation from new development a footbridge was incorporated in the design to accommodate an existing footpath. It was closer to the settlement and severed an existing footpath used by dog walkers. As the current bypass is single carriageway and positioned further east beyond the development area, it is not anticipated that either the pedestrian demand or need to cross such a wide road would require a costly footbridge. There are also large linked green open spaces incorporated within the development masterplan to support recreational walking. However at grade crossing points will be designed as a key feature where necessary to allow rights of way to be connected.

 

Q Can the old A140 then be pedestrianised or at least the road become where the local buses can easily collect and deposit from?
A As of 21st April 2017 by Mike Haslam Planning and Development Consultant

The old A140 will continue as current but of a lesser use and status. This is one of the measures the parish council, District Council and highways authority might progress various options, particularly in the village commercial centre, supported by adopted policy of the Area Action Plan.

 

Q Will there be any cycle routes alongside the bypass?
A As of 16th March 2017 by Canon Consulting Engineers

No, this is not a formal detail for this class of road but the ‘old’ A140 will make for an attractive cycle route and should be considered as part of above. Similarly, the spine road infrastructure and planned green open space in the development masterplan will allow for such use.

 

Q What is the safest speed to keep horrendous accident statistics down?
A As of 16th March 2017 by Canon Consulting Engineers

The lower the speed the better chance of stopping early which is safer this is consistent with Government guidance on setting speed limits. It is also consistent with the existing mix of speed limits on the A140 that for example in Suffolk have seen a significant reduction in accidents. The difference in speed to the journey being made is insignificant when compared to the delays currently experienced at peak periods in the centre of Long Stratton.

Q:Have the Councils agreed the bypass as shown on Norfolk Homes and Norfolk Land’s consultation?

A: By South Norfolk District Council as of July 2017

No, whilst a ‘bypass corridor’ in the same broad location has been identified in the adopted Long Stratton Area Action Plan, the design and alignment of the bypass is still being discussed by Norfolk Homes, Norfolk Land, Norfolk County Council and South Norfolk Council.

Q:Will the upcoming planning applications include improvements to Hempnall Crossroads?

A: By South Norfolk District Council as of July 2017

Improvement measures will be secured as part of the development, but this is something that Council officers are discussing with the developers.

Q: When will the bypass be built?

A: By South Norfolk District Council as of July 2017

There is a requirement in the Long Stratton Area Action Plan to provide the bypass before the occupation of the 250thnew dwelling in the development, unless there is clear evidence this would not be financially possible and provided any later provision is acceptable in highway terms. The Council is working closely with the developers to identify when the bypass can be delivered and to help identify sources of funding for the developers to assist with this delivery.

Q: What will the impact of the development be on the existing road network, for example the surrounding A140?

A: By South Norfolk District Council as of July 2017

The developer will be required to submit a full transport assessment to support their planning application showing the impact of their development proposals including the bypass on the local road network.

Q: The dual carriageway proposal included for embankments, cuttings and noise attenuating surfacing. Will the new proposal also include the latter?

A: By ASD Consultants as of July 2017

Since the original proposals for the County Council By-Pass, surfacing technology has made great strides and nowadays most surfacing materials are low noise. The old hot rolled asphalts with pre-coated granite chips are no longer specified for the surface course of by-passes and higher speed roads, being replaced by Stone Mastic Asphalt also called Stone-Matrix Asphalt (SMA).

Although more expensive than the traditional asphalts it provides a textured, durable and rut resistant surface course. The material produces a similar finish to that of open graded asphalt, is stronger while maintaining the same lower noise characteristics.

Basically SMA is now the specified surface course material for all by-passes and higher speed roads and will be specified for Long Stratton.

Q: When is the bypass expected to start being constructed?

A: Norfolk Land Ltd as of August 2017

The SNC adopted policy says its provision to be by 250 dwellings: subject to viability.It is not financially viable for the development to provide its proper (substantial!) share by this time, so the developers maintain their position (as placed before SNC, NCC and the Inspector presiding over the Inquiry for adoption of policies) it will be quite a bit later. However, the developers continue to work with both SNC and NCC to try and attract government or other funding to secure an earlier delivery.

Q: “There is a requirement in the Long Stratton area action plan to provide the bypass before the occupation of the 250th new dwelling, unless there is clear evidence this will not be financially possible”.I paraphrase from your own text.

This sounds like an opt out clause to me and I would like to know who will decide if “it is not financially viable and if the later provision is acceptable”?

Along with many other villagers, I can see a scenario of 1800 homes, plus all the other homes already planned and built, and no bypass!!!!

What guarantees do we actually have?

A: Norfolk Land Ltd as of August 2017
The developers, land owners and councils are all adamant to deliver a bypass.
Whilst it’s unlikely to be provided by 250dwellings due to viability (e.g. the land for 250 dwellings is not
considered to be worth enough if all its sale proceeds are used to fund the development’s substantial share at this stage!), the developers continue to work with both SNC and NCC to try and attract government or other funding to secure an earlier delivery.
It is proposed that the developers’ planning application will include a fully detailed scheme for the bypass and willingness to enter legal agreements to secure it.

SNC will be the ultimate authority, working with NCC, who issue any planning permissions and audit any submissions put to them eg viability and delivery of bypass.

Q: 12,000 to 18,000 vehicles a day on the bypass will generate lots of noise both on the bypass and at the new roundabouts due to accelerating and braking. Low noise surfaces reduce tyre noise, but do nothing to reduce the noise from exhausts and engines. Further, low noise surfaces settle down and soon become noisier. Currently the houses to the east have no noise from the east. What measures are going to be incorporated to manage the additional bypass and roundabout noise?

A: Jim Smith Sustainable Acoustics Ltd

Noise contours have been calculated using impervious bituminous road surfaces. The reality should be far better than this (see ASD Engineers comments on road surface for bypass). Calculations do not differentiate between exhaust, engine and tyre noise. The correction applied for a lower noise road surface does not regard noise from the exhaust and engine, which would remain the same. The primary mitigation measure, to reduce traffic noise on the eastern houses, is the building of the bund  which will also include the cutting on the road side. This will provide an effective 2 meter barrier between the road source. Additionally, the building of new houses to the east of the existing houses will also provide further screening.The combination of bund and new houses will result in noise levels well within those that would be deemed desirable in new dwellings (as defined in BS 8233).

Q: With so many more roundabouts and junctions being introduced surley that will have a great impact on noise levels and will not be good for the enviroment or efficiency of our vechicles with all that acceleration and deceleration. Having lived near a roundabout previously a roundabout is a lot noisier than a straight road with junctions that we have at present?

A: By Norfolk Land Ltd as of September 2017

Roundabouts are deemed to be the most effective (in managing north-south traffic flows with safety) alongthe proposed bypass.  Each one is proposed as necessary:-
1. Northernmost, near Church Lane – to perform as access/egress to bypass as well as estate access to land to be developed to the west and continue access to north of village.
2. Second down, new location – to give access to new housing to east, to give safe and convenient route for in/out traffic (as to avoid traffic ‘rat running’ and using the current route through village centre).
3. Third down, Hall Road – to facilitate existing east-west connectivity and improve access for necessary traffic to village centre.
4. Fourth down, picking up diverted Parkers Lane – both continuation of access to southern part of village (where current route of A140 to be stopped up) and giving hgv standard of access for new employment allocation here.

Q: Surely the guarantee of a by-pass is simple. SNC must not approve any housing development before the full bypass funding from the government and developer is guaranteed. Are the SNC prepared to commit to this?

 

A: by South Norfolk District Council as of September 2017

The Long Stratton Area Action Plan adopted in 2016 by the Council is clear that before any housing is permitted on the allocation, there shall be a phasing and delivery mechanism that will secure delivery of the bypass. The Council is fully committed to this.

 

Q: What is the junction layout going to be for people getting into and out off Long Stratton? If it is a side turning it will be a nightmare for people if they need to cross the stream of traffic to get onto or off the A140?

A: By Norfolk Land Ltd as of September 2017

Junctions for access to both new development and the village existing off the bypass will be roundabouts for ease of access/egress. Sufficient and convenient roundabouts are planned to maximise accessibility and minimise both traffic hold ups and ‘rat-running’ (eg through traffic using The Street).
