Where was the project located?

The M4 junction 10 is the exit for the A329(M) leading to Wokingham, Bracknell and Reading (east) in Berkshire.

Why was the scheme needed?

Junction 10 is a major interchange connecting the M4 with the A329(M). The junction is affected by peak time congestion, particularly at the merges from the M4 onto the A329(M), leading to traffic queues on the link roads back towards the M4.

What work was carried out?

The main construction work started in January 2015 and was completed in February 2016.

Works to widen the link roads from the M4 onto the A329(M) are now complete and the junction is operating with the new layout. Work to install additional lane designation signs and road markings was also completed in January.

Outstanding electrical work to the new road signs will be completed during February 2016.

How did this benefit road users?

This scheme provides the following benefits:

  • improvements to the link roads between the M4 and the A329(M) will improve journey times and reduce accidents through the junction
  • promote growth within key developments in Wokingham and Reading
  • help facilitate the delivery of approximately 6,000 additional jobs and 10,000 homes by 2020, which are key aspirations within the Wokingham core strategy
