Project Details
Description
The works are required to maintain the safety and integrity of a section of the M74 southbound hard shoulder between Larkhall and Blackwood, South Lanarkshire, covering an area of 2.5ha. Resurfacing works are required on the southbound (SB) carriageway due to surface defects and structural defects identified across the hard shoulder and patches of 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 hard shoulder road surface, and potential carriageway lane, 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 works expected to commence the September 2025 during nighttime hours. The duration of which is still to be determined.
TM will likely consist of overnight hard shoulder lane closures. A diversion route is likely not needed however; specific traffic management is not yet determined.
