Project Details

Description

Overlay resurfacing works are required to temporarily repair the existing A90 southbound carriageway surface due to structural issues such as cracking and water ingress. The existing carriageway is comprised of reinforced concrete and is currently failing, nearing the end of its design life. The works are proposed as a short-term repair, while optioneering to determine long-term pavement treatment is undertaken. Similar overlay works have been undertaken in December 2025 for the A90 northbound carriageway, with the southbound overlay proposed to comprise a similar 50mm build‑up, consisting of a 20mm SAMI layer and a 30mm thin surface course.

Additionally, crossover improvements are required to enhance the resilience of the trunk road network, and comprise the construction of three new crossovers, and the upgrading of an existing crossover. At each crossover location, the scope of works includes the removal of existing pavement and construction of new pavement, together with the removal of existing Vehicle Restraint Systems (VRS) and installation of new VRS. The installation and removal of VRS will extend slightly beyond the extents of the crossovers.

The scheme is located along the A90 Brechin Bypass, north of Brechin, between Each Inchock and Keithock, Angus. This section of the A90 is a dual carriageway, and the scheme is approximately 6.30 kilometres long, with a total area over 10 hectares.

The plant and machinery required for the overlay and crossover improvement works are as follows:

  • Planer/miller to remove existing surfacing;
  • Asphalt/aggregate truck;
  • Rollers for smoothing of new surfacing;
  • Concrete truck;
  • Excavator(s);
  • Post driver; and
  • Vehicles including access vans, and material delivery vehicles.

The proposed construction is programmed to be undertaken and completed within the 2025-2026 financial year, proposed for February and March 2026. TM will in place 24/7, with works likely to be undertaken during day and night-time working hours to reduce the construction period. The works will last approximately four weeks. TM will entail a combination of contraflow, overnight convoy and lane closures.
