Project Details

Description

BEAR Scotland has been commissioned by Transport Scotland to demolish the existing M80 7-8 G90 gantry on the northbound (NB) carriageway, relocate the existing M80 7-8 G20 gantry, as well as remove and install new signage and vehicle restraint systems (VRS) over a length of 0.7km (Approx. 1.1ha).

The construction activities for the works are as follows:

  • Installation of traffic management (TM) on M80 NB including temporary vehicle barriers (various phases, locations and arrangements).
  • Establish site compound, welfare facilities etc. (various phases, locations and arrangements).
  • Remove existing VRS at works locations.
  • Excavate and pile for new foundations at locations of new gantry, one foundation in NB verge and one foundation in central verge.
  • Cast reinforced concrete for new foundations at location of new gantry.
  • Install a new post mounted sign upstream of existing location of M80 7-8 G20, in NB verge.
  • Remove existing gantry steel superstructure from M80 7-8 G20 and installing it on the new foundations at location of the new gantry.
  • Touch up paint on gantry steelwork.
  • Dismantle existing M80 7-8 G90 gantry including demolition of foundations down to 1m below ground level.
  • Demolish foundations of gantry M80 7-8 G20 down to 1m below ground level.
  • Install new VRS at existing and new gantry/sign locations.
  • Apply road markings on M80 between Junctions 7 and 8.
  • Remove all TM.

The works are currently programmed to be completed within 2026/2027 financial year, with works expected to begin on the 13th of April 2026. Works are programmed to be completed over two to three months as a combination of day and night-works (07:00 - 16:30 and 19:30 – 06:00). Multiple phases of TM will be required for the duration of the works, these include:

  1. NB hard shoulder closure, potentially with narrow running lanes and a partial closure of Lane 1 to allow all works to be undertaken in the NB verge at various locations.
  2. NB Lane 3 closure with hard shoulder running, potentially with narrow running lanes. A partial Lane 2 closure, along with a Lane 3 southbound (SB) closure with hard shoulder running to allow all works to be undertaken in the central reserve.
  3. Full overnight closures of the M80 in both directions during lifting out and in of the M80 7-8 G20 superstructure and for demolition of M80 7-8 G90 gantry.

Location

The scheme lies on the M80 NB carriageway at Dennyloanhead, within Falkirk Council and is predominantly bordered by both arable land and small sections of woodland.
