Junction 30 is located approximately four miles to the east of Exeter in Devon. The Highways Agency will be carrying out works to widen the southbound exit slip road and improve the traffic signals on the roundabout.
Installation of traffic management will commence overnight on Sunday, 25 January and will continue until the Spring.
Highways Agency Project Sponsor Dave Stock, said,
Junction 30 suffers from congestion and subsequent delays in peak periods. We are widening the southbound exit slip road from three lanes to four lanes at its approach to the roundabout. We are also going to install intelligent traffic signals on the roundabout that will control the volume of traffic according to road capacity.
By doing this we can improve traffic flows and reduce overall queue lengths at the roundabout and achieve wider benefits in supporting growth in the surrounding area.
The work is one of 14 Highways Agency pinch point schemes taking place in the South West. The pinch point programme provides small scale improvements that can deliver big returns by easing congestion and making journey times more reliable for road users as well as helping to boost local economies and drive economic growth.
There will be overnight closures between 8pm and 6am on both southbound slip roads, lane closures on the northbound exit slip road and single lane running on the roundabout for traffic signal works.
For the duration of the works there will be a 50mph speed restriction on the M5 from the middle of Junction 29 to the middle of Junction 30 for the safety of our road workers and road user. The speed restriction will also apply to the southbound exit slip road at Junction 30.
