Work to upgrade the junction of North Hill, North Road East and Clifton Place will get under way on Tuesday 11 April.
Originally due to start in March, the upgrade was rescheduled to allow for works on Saltash Road (Pennycomequick Hill) to be completed.
Improvements at the junction, which is one of the busiest in the area, will include new signals, pedestrian crossings and footways.
Touch-button crossings will be installed on all four arms of the junction, improving safety for everyone walking along this busy route, including pupils at nearby schools.
The extra crossings will also mean the left-hand turn can be reopened, enabling drivers to access Mutley and Alexandra Road without having to go via Clifton Place, significantly reducing the number of vehicles using this narrow residential street.
New signals fitted with more responsive ‘MOVA’ units will replace the ageing equipment currently in place and footways will be improved – and widened where necessary.
Works, which are expected to finish in September, will include new ducting, footway reconstruction and lining on both sides of North Hill (between Bedford Terrace and Lawrence Road) and North Road East (between the North Hill car park entrance and North Hill).
Temporary signals will be in use throughout the works but manually operated at peak times (8am to 9.30am and 3pm to 4pm). There will also be no left turn from North Hill into Clifton Place.
Please allow extra time for your journey.
