M40/M42 interchange: smart motorway
The M40/M42 interchange is frequently congested at peak times, affecting both local journeys and long distance traffic between London and Scotland. Major new developments in Birmingham, Solihull and the Black Country will also increase demand on the junction.
Over the last year, we have been gathering information about the road and the areas that surround it to develop the design for the M40/M42 Interchange smart motorway project.
Our proposed regulations include the introduction of variable mandatory speed limits to the M40 / M42 Interchange, including slip roads, between M42 J3 and J4 and M40 J16 as part of the M40 / M42 Interchange Smart Motorway Scheme.
Following the consultation period, we will produce a report which will provide a summary of the responses, the decision whether to proceed or to modify the proposals and allow us to respond to any comments made.
The M40/M42 interchange is very important for local traffic and forms an important link for long distance traffic travelling between London and Scotland.
Congestion already occurs frequently at peak times at the interchange.
This scheme aims to:
- reduce congestion and delays
- improve journey time reliability
- maintain a high standard of safety
- support economic growth and job creation
