Essential Bridge Refurbishments


UPDATE (11/03/22): Maintenance on the M8 between Junctions 25 (Cardonald) and 25A (Braehead) has been rescheduled and will now commence on Tuesday 15th March 2022. OVERNIGHT prep works will take place prior to this date with a total closure of the M8 westbound carriageway required between Junctions 24 and 26 on Sunday 13th March 2022. On Monday 14th March 2022, a total closure of the M8 eastbound carriageway between Junctions 24 and 26 and a double offside lane closure on the westbound carriageway will be required. Diversions will be signed for road users. All other details remain as published below. 

Amey, on behalf of Transport Scotland as part of the Network Management Contract for the South-West Trunk Road Unit, are undertaking essential bridge refurbishment work on the M8 between Junctions 25 (Cardonald) and 25A (Braehead) from Monday 7th March until Thursday 30th June 2022. Traffic management will be in operation throughout the duration of the works. 

This scheme, with a value of approximately £2,000,000, will benefit road users on this key route, by ensuring the continued safe and reliable operation of the trunk road and reducing the need for more extensive maintenance in the future. 

The refurbishment works are being undertaken on three bridges between Junctions 25 and 25A of the westbound M8 motorway and include bridge deck waterproofing, concrete repairs, parapet upgrades, drainage improvements and resurfacing works.  

The traffic management for this scheme involves the works being undertaken in four phases. Phase 0 is required to improve crossovers prior to the works commencing. Contraflow will be in operation throughout all phases 1-3, which will involve a single lane crossover from the westbound outside lane to the eastbound outside lane. The entry crossover is in proximity to the M8 Junction 25 westbound off-slip, while the exit crossover is in proximity to M8 Junction 26 westbound on-slip at Hillington. The programme of works in the westbound direction is as follows: 


  • Phase 0 | Pre-works: Reduced width outside lane 


  • Phase 1 | Offside Lanes: The hard shoulder, slip lane, and lane one of the M8 between Junctions 25 and 25A will run as narrow lanes.  


  • Phase 2 | Central Lane: The hard shoulder, slip lane, and lane three of the M8 between Junctions 25 and 25A will run as narrow lanes. Works will take place with traffic running on either side. During this phase, no wide loads are permitted to pass in the westbound direction. 


  • Phase 3 | Nearside Lanes: Lane one, lane two, and lane three will run as narrow lanes.  


Overnight total closures in the westbound direction will required between each phase of the works to allow for re-positioning of traffic management. It is envisaged that these overnight total closures will span over a maximum of two nights, with lanes in operation in the daytime. 

To accommodate all works phasing on the westbound carriageway, the eastbound direction shall have a single outside lane closure in place between Junctions 26 (Hillington) and 25 (Cardonald). Phase 0 will initially require an eastbound overnight total closure to facilitate the deployment of traffic management. 

During all phases, all slip roads shall remain open and temporary safety barriers shall be in place to delineate live traffic from the works.  

Average speed traffic cameras will be in operation throughout the duration of the works to ensure speed limit compliance and safe working conditions for our maintenance team. Access for emergency service vehicles will be maintained throughout these works. 

Please allow extra time to complete any journeys through the works area. We thank road users for their patience while this essential maintenance is underway.  

Our operatives will follow strict physical distancing and hygiene protocols throughout the programme, in line with the Scottish Government’s COVID-19 guidance. 

Please note, all schemes are weather dependent and may be cancelled or rescheduled if weather conditions are not favourable.
