The speed limit along most of the stretch between Manadon and Derriford will return to 40mph from Friday 1 July.
Plans to reinstate the 40mph limit were advertised in November and approved earlier this year.
A temporary reduced speed limit of 30mph was introduced between Budshead Road and Powisland Drive in 2018, while work was carried out on the Derriford Transport Scheme.
It was later extended to cover the stretch between Manadon Roundabout (Outland Road) and Runway Road and has remained in place as a trial, for further review.
Following the trial, the 40mph limit is to be reinstated along most of this stretch, with the exception of two sections:
- The stretch between Derriford Roundabout (including the roundabout itself) and Runway Road. This will remain at 30mph as it is a single carriageway with cycle lanes, as well as pedestrian measures introduced as part of the Derriford Transport Scheme. (The 30mph speed limit has also helped to address earlier issues turning into and out of Powisland Drive)
- The inbound side from Derriford Roundabout (including the roundabout itself) to Charlton Road, which will also remain at 30mph, as recommended by a safety audit for the upcoming junction improvement scheme at Charlton Road.
Councillor Jonathan Drean, Cabinet Member for Transport, said: “We have made it a priority to improve traffic flow and make it easier for people to get around the city. As part of this we made a commitment to increase the speed limit from 30mph to 40mph along this section of Tavistock Road.
“We have taken into account speed and collision data from before and during the 30mph trial and, of course, the relevant safety recommendations and we are confident these changes will help to improve journey times along this route.”
New signs have been installed to reflect the changes. Crews will start to uncover them on Thursday night, ready for Friday morning.
