Project Details

Description

The works are required to maintain the safety and integrity of the northbound (NB) section of the A90 through Dundee, covering an area of 1.7ha. Resurfacing works are required on the NB carriageway due to surface defects and structural defects such as cracking and depressions. The works will include both full reconstruction and partial reconstruction of the carriageway, the location of which will be determined by the investigation coring. The works are required to improve the safety and road quality for road users.

Construction activities will consist of structural inlays. 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;
  • 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 (ending on 1st April 2026) for approximately one-week during both dayshifts and nightshifts.

TM will consist of a contraflow system on the southbound lanes. Due to the contraflow management, a main diversion route is not needed, however, the on slip and off slip roads of the A90 within the scheme extents will require localised diversions routes. These have yet to be confirmed.
