Project Details
Description
The works are required to maintain the safety and integrity of a northbound (NB) section of the M74 south of Larkhall and north of Blackwood, South Lanarkshire, covering an area of 1.2ha. Resurfacing works are required on the NB carriageway due to surface defects and structural defects identified across the carriageway. These defects include fretting, rutting and some isolated cracks. The works are required to improve the safety and road quality for road users.
Construction activities will consist of structural inlays, ranging in depth from approximately 30mm-300mm. Treatment will involve using TS2010 surface course. Construction activities and relevant plant/machinery will include:
- Installation of Traffic Management (TM);
- Removal of the existing road surface to the required depths by planer;
- Compaction and flattening of the material by roller wagon;
- Laying of the new road surface by paver for structural inlays, with depths ranging between 30 to 300mm;
- Sealing of road joints to prevent water ingress;
- Transporting of the removed road material by disposal trucks;
- Installation of new road markings and new road studs; and
- Removal of TM upon scheme completion.
The works are scheduled to be completed within the 2025/2026 financial year with approximately eight nightshifts.
TM will likely consist of overnight NB lane closures. A NB diversion route will be put in place where traffic will leave the M74 carriageway at Junction 10 and utilise the B7078 Carlisle Road, through Kirkmuirhill and Blackwood, until the A71 Canderside Toll where traffic will rejoin the M74 at Junction 8.
