Oldbury Viaduct – M5 junctions 1-2 progress update

The next stage of Highways England’s main repair works on the M5 between junctions 1 and 2 (Oldbury Viaduct) went live at the end of July.

For safety reasons the capacity on this stretch of motorway has been reduced which is expected to cause delays. The usual three lanes in each direction have been reduced to two lanes in each direction with a reduced 30mph speed limit.

People travelling across the country are being urged to consider alternative routes such as the M42 and M6 or M6 Toll. This is to reduce the amount of traffic heading through the roadworks in this busy part of the network and to reduce the potential impact on local roads. To help with this, Highways England have made changes to the road layout at key junctions in the area, including at M6 junction 8 southbound and M5 junction 4a northbound. These traffic management restrictions will be in place until autumn 2018.

As with any new traffic management scheme there is always bedding in period before things settle down, Highways England will continue to monitor this and thanks you for your patience.

Plan your journey

Highways England is advising to expect delays at these junctions and recommend that where possible you:

  • plan ahead
  • allow extra time for your journeys
  • consider using alternative routes
  • change modes of transport
  • car share
  • work from home

What next?

Engineers have started to remove the existing surfacing and waterproofing on the southbound carriageway. Over the next few weeks they will be inspecting the reinforced concrete deck and assessing the full extent of the concrete repairs required. In addition they will be preparing the reinforced concrete deck joints for repair by removing the existing concrete using specialist hydro-demolition techniques
