A34 Chieveley / M4 Jct 13 Improvement

Project Outline

The main components of the scheme are:

  • 3km of new dual two lane carriageway forming the new A34
  • Three 'top-down' bridges forming underpasses to the M4, westbound on-slip road and the eastbound off
  • New A34 slip roads forming a grade separated interchange to interact with the existing M4 Junction
  • Six new slip road over-bridges
  • New access arrangements for Chieveley service area, Travelodge, Hilton Hotel and maintenance depot
  • New local road and by-way network connections
  • New equestrian over bridge crossing the A34 south of J13
  • Refurbish 3km of carriageway on the M4
  • New sign gantries on the A34 approach to Junction 13
  • The scheme will alleviate the current traffic delays, removing one of the worst bottlenecks in the UK highway network.
