Area 1

Area 1 consists of the A30 and the A38 trunk roads to the west of Junction 31 of the M5 near Exeter, incorporating 110 miles (177 kilometres) and 70 miles (112 kilometres) respectively.


Where was the project located?

The Carkeel junction is located on the A38 approximately 1km to the west of the Saltash Tunnel in Cornwall. It links the A38 trunk road with the A388 to Carkeel and the B3271 to Saltash and South Pill.

Why was the scheme needed?

The Carkeel Junction suffered from severe congestion and subsequent delays in particular on the A38 westbound approach in peak periods.

What work was carried out?

We are widened the westbound approach from two to three lanes and widening the westbound exit to allow for a two lane exit and installed a pedestrian footbridge on the A38 eastern arm.

How did this benefit road users?

The scheme improvements will resulted in improved flow through the junction and reduced conflicts between merging traffic streams. The proposals achieved wider benefits in supporting growth in the surrounding area, such as development at Carkeel and Saltash.

Details of scheduled roadworks are provided to help you plan your journey. Please note that works are weather- and resource- dependent and may need to be cancelled at short notice. This information is not updated in real time so please check Traffic England for current traffic conditions. Diversion timings are approximate and act as a guide only.

Will there be roadworks?

Yes, roadworks will be needed to create the additional lanes on the westbound approach and westbound exit to Carkeel roundabout and to install the footbridge on the A38 arm. There is the potential for significant delays during the construction of the scheme and it is advised that you plan your journey to allow for extra time travelling through these works.

Further information will be published nearer to the time of construction.

How will you manage traffic?

Traffic will be managed by a series of lane closures with occassional overnight carriageway closures.

Will there be diversions?

Where necessary local established diversion routes will be employed during the overnight closures.
