01 Welcome To The Chelmsford North East Bypass Public Consultation

The purpose of this public consultation is to present the junction designs and local access proposals for the Chelmsford North East Bypass.

What is this Public Consultation about ?

In 2006 the County Council held a consultation in which a number of route options for Chelmsford North East Bypass were displayed. A large number of people attended the exhibitions, completed questionnaires, posted comments in the visitors book and made representations to the Council. We would like to thank all those who responded. 2006 Consultation In March 2007 the County Council selected a preferred route for the Chelmsford North East Bypass.

The 2006 exhibition did not indicate details of the junctions at each end of the bypass, nor did it explain how local roads, footpaths and bridleways that crossed the route would be treated.

Suitable designs for connecting the bypass to the A12 at Boreham, to the A131 Great Leigh’s Bypass at Deres Bridge and to the local road network have now been progressed. Ways of mitigating the effect of the bypass on the local roads, footpaths and bridleways that cross the line of the bypass have been investigated. White Hart Lane The outcome of this work is presented here for you to comment on. Your comments will be used in the decision making process when a preferred junction strategy is chosen by the County Council.

05 Boreham Interchange Summary

Engineering Considerations Boreham Interchange Proposal N • New bypass bridges over the Railway.

• Link roads pass over the A12 and Boreham Interchange.

• Generals Lane is replaced by a link over the railway.

Walter • Maximum height is approximately Hall 7 metres (22 feet) above the existing junction. Bypass

Braintree / • Bridging over the railway and A12 results in structures Great Leighs

that are relatively simple and economical to build. Quarry access

• Options which would involve the new road passing under the railway were considered but dismissed on a combination of cost and technical grounds.

• During future stages of the scheme mitigation measures will be developed to reduce environmental impacts. These could include:

- Use of noise reducing road surfacing and provision of noise insulation to properties. - Careful landscape design including planting to break up the proﬁ le of the embankment. Junction Costs - Habitat enhancement and or creation, installation of wildlife passages and barrier fencing. The estimated junction cost is £116m

09 Chelmsford North East Bypass

With the selection of appropriate junction designs at Boreham and at the A131 Deres Bridge, a complete Chelmsford North East Bypass Scheme will be achievable.

Scheme Costs Deres Grade Separated Option Deres At-Grade Option N The overall scheme cost is estimated to be between £229m and £262m.

Value For Money The performance of highway schemes can be assessed by comparing the overall cost of the scheme with the economic beneﬁ ts that will accrue over its lifetime. The results of this assessment can be expressed as a Beneﬁ t to Cost Ratio (BCR). The overall BCR for; • Whole scheme with Deres At- Grade Option = 4.5 • Whole scheme with Deres Grade Separated Option = 4.2 Highway schemes can normally be said to provide ‘High’ value for money, if they have a BCR of over 2. High value for money schemes are more likely to receive funding from central Government.

Trafﬁ c Effects The Bypass will provide a much faster route for trafﬁ c heading between the A12 and the A131/A120. The following table compares expected average journey times, between the A12 at Boreham and the A131 north of Deres junction in 2031, with and without the Bypass in place: Average Peak Hour Journey Times between A12 and A131 in 2031 Without Bypass 21 mins With Bypass 6 mins (At-Grade Deres option) With Bypass 1 (Grade Separated 5 /2 mins Deres option)
