V4 Pedestrian Crossings

The Western Expansion Area (WEA) is situated between Crownhill and Stony Stratford.

Once completed it will include 6,550 new homes, employment land, green open spaces and parks, a main street with retail and leisure units and schools. 

Occupation of homes in the Western Expansion Area (Whitehouse and Fairfields) began late in 2015 and is now increasing rapidly.  However there were no safe pedestrian crossing facilities across the grid roads.  A toucan crossing is now in operation between Fairfields and Fullers Slade.  The pedestrian crossing schemes are part of the urgent work to provide safe pedestrian and cyclists crossings in the Western Expansion Area.


Junction 25 Whitehouse Underpass, V4 Watling Street, between Whitehouse and Two Mile Ash

The General Arrangement (PDF, 395KB) plan shows the location of the underpass.

Construction works will commence on 10 June 2019 until Spring 2020.  This is a major engineering project with many major services and utilities which will be required to be diverted.  Anglian Water will also be constructing a new pipeline along the V4 from the H3 to H4.  We are also working with L&Q Estates (previously known as Gallagher Estates) to support the next phase of Western Expansion Area.

To enable the works, the road between Crownhill roundabout (H4) and Fairways roundabout (H3) will be closed. The current redway between this stretch will also be diverted.

Why is a road closure required?

The building of a new underpass is a major engineering project, requiring significant excavation. Many services such as telecommunications will need to be diverted, as well as utilities that include gas and water. Because of the number of utilities and services involved, this is a complicated and timely process, which has added to the time required to complete the underpass.

Whilst we have a closure in place to build  the underpass, Anglian Water will carry out works at the same time to  build a new pipeline along the V4 from the H3 to H4 to ensure that water pressure is maintained for residents now and in the future.

MKC worked with local ward councillors before deciding on the road closure. Local knowledge and issues were factored into the decision to proceed with the current arrangement. This included making sure that good communications are in place, including some road show events (see below) to provide people with an opportunity to ask questions and find out more about how they will be affected.

We looked at an option to build a temporary road to maintain access. The cost of this would have been approx. £600,000 and the road would still have had to be closed for three months to complete these works. After much consideration, this was rejected based the need to still have a road closure for utility works and the costs.

During the road closure, the diversion route will be monitored and traffic management signage can be amended if needed.
