Project Details

Description

BEAR Scotland has been commissioned by Transport Scotland to carry out embankment stabilisation works and resurfacing of the carriageway on a section of the A85 trunk road east of Lochearnhead (see Figures 1 and 2 below).

Both schemes cover the same scheme extents with the embankment works involving the construction of a buried concrete road edge beam along the westbound (WB) verge of the A85 carriageway extending approximately 1,425 metres (m) and covering an area of 0.86 hectares. The beam dimensions are 0.3m wide and 0.5m deep and will be installed over a length of 780m. The WB verge will be reinstated above the concrete beam and grass seeded. Following the works, the height of the WB verge will be reduced across the whole scheme extents in line with the carriageway (1425m in total). Vegetation management may be required if deemed to be necessary.

The resurfacing works involve the resurfacing of the A85 eastbound (EB) and WB carriageways extending approximately 1,374m and covering an area of 0.98 hectares. Finalised design for the surface course and binder/base are still to be confirmed. Road markings and studs will be reinstalled following the works.

Embankment stabilisation works are programmed to commence in summer 2025, currently programmed for July, and will utilise a daytime working pattern (07:00 – 18:00) over 3 weeks. Resurfacing works will commence in September 2025 over 9 nights by utilising night-time working pattern (19:00-06:00). Changes to the programme may result in amendments to these dates.

Traffic management (TM) for the embankment works will consist of WB lane closures facilitated by two-way temporary traffic lights. TM for resurfacing works will consist of full night-time road closures with regular amnesties. Local access and non-motorised road users (NMRU’s) will be accommodated within the TM as much as is reasonably practicable.

Location

The schemes are located on a semi-rural stretch of the A85 east of Lochearnhead, in the Stirling Council Local Authority. National grid references (NGR’s) for the for the embankment works are NN 61602 24198 - NN 60238 23939 and NGRs for resurfacing works are NN 61593 24196 - NN 60281 23951.
