Work will get under way on Wednesday 7 January 2015 to upgrade the traffic signals and pedestrian crossing at the Bucks Road/Circular Road junction in Douglas.
The Department of Infrastructure scheme will also involve the resurfacing of a section of Prospect Hill.
A significant proportion of the improvement work will be carried out during the evenings and weekends to minimise the disruption to motorists and pedestrians.
The scheme is necessary in order to replace the traffic signals at the junction of Bucks Road/Circular Road, which have reached the end of their operational life. Crews will excavate across the carriageway to install new ducting to link the signals. Temporary traffic lights will be in operation for the duration of the work.
The opportunity will also be taken during this phase of the scheme to upgrade the kerbing and replace tactile paving at all crossing points.
The Prospect Hill carriageway will be relaid from its junction with Ridgeway Street to its junction with Albert Street. This will be undertaken in two phases to maintain traffic flow around the capital. Phase one, from Finch Road to Ridgeway Street, will start on Monday 2 February 2015, with phase two, from Finch Road to Albert Street, commencing on Monday 9 February.
Preparation work, which involves planning out the existing road surface and adjusting ironwork such as gully covers and manhole lids, will be carried out during evening road closures from 6.30pm to 6.30am. Weekend daytime closures will be in place on 7-8 and 14-15 February to enable the resurfacing to be completed.
The highway work will be completed and the new traffic signals operational by Monday 16 February.
Infrastructure Minister Phil Gawne MHK said:
'This scheme will result in improvements for motorists and pedestrians, as well as replacing traffic signals that are life expired. Our staff will be working at weekends and evenings to finish the job as quickly as possible and reduce the potential disruption. I'd like to thank the public in advance for their understanding and cooperation.'
