Project Details

Description

BEAR Scotland has been commissioned by Transport Scotland to carry out resurfacing works on the A720 Dreghorn eastbound carriageway. The works will consist of a mix of inlay depths of 50mm and 120mm. The works will also involve the reinstatement of road markings and studs for a length of 1150m (approx. 1.005ha).

The construction activities for the resurfacing procedure are as follows:

  • Set up traffic management (TM) and mark out site.
  • Milling of existing bituminous material by road planer.
  • Jackhammer and compressor for breaking up surfaces not accessible by planer (e.g. around gullies).
  • Loader/excavator used to collect and move excess material.
  • Sweeper to collect loose material and provide clean laying surface.
  • Milled out/excavated materials all taken off site.
  • Tack/bond coat laid.
  • Base / binder material laid and compressed by paver (where required).
  • Material compacted using a heavy roller.
  • New bituminous surface course material laid by paver.
  • Material compacted using a heavy roller.
  • Mechanical sweeper to collect loose material.
  • HGV for removal and replacement of material.
  • Road markings and studs applied where necessary (in accordance with the Traffic Signs Manual, Chapter 5).
  • Remove TM and open road.

The works are currently programmed to be completed within the 2025/2026 financial year, with works currently expected to begin on 8th April 2025. Works are programmed to be completed over four nights (20:00 – 06:00). TM will involve four nighttime full road closures of the A720 eastbound carriageway with a signed diversion in place from the A720 Dreghorn eastbound offslip to the Lothianburn eastbound onslip. The details of the eastbound diversion are as follows:

  • Leave the A720 using the Dreghorn eastbound offslip.
  • Take the second exit at the roundabout to turn onto Redford Road (B701).
  • Turn right onto Oxgangs Road (B701) at T junction.
  • Take the second exit at the roundabout to stay on Oxgangs Road (B701).
  • Turn right at the Biggar Road junction onto Biggar Road (A702).
  • Take the first exit at the Lothianburn North Roundabout to use the Lothianburn eastbound onslip to rejoin the A720 Eastbound.

Location

The scheme lies on the A720 carriageway southwest of Swanston (Figure 1), within the City of Edinburgh Council and is predominantly bordered by residential properties.
