Amey, on behalf of Transport Scotland, is undertaking a major bridge refurbishment project, including rail and slip road upgrades, on the M8 at Junction 26 (Hillington Interchange). These essential works, valued at approximately £9million, will be delivered over five phases from September 2025 until Spring 2026 and include significant repairs and upgrades to four key bridge structures, addressing vehicle parapets, structure waterproofing, safety barriers, and carriageway surfacing.
PHASE ONE
Phase One will take place from Monday 8th September until Wednesday 1st October 2025 under a 2+2 contraflow on the M8 mainline carriageway at Junction 26 (Hillington Interchange), which will involve closing Lane Two and Lane Three of the eastbound carriageway and narrow running lanes to facilitate. In addition, a total closure of the M8 Junction 26 eastbound on-slip road will be implemented for the duration of Phase One, and traffic will be diverted as follows:
North of Hillington Interchange for Vehicles in Renfrew/Braehead Area:
South of Hillington Interchange for vehicles in Hillington Industrial Estate area:
The M8 Junction 25A westbound off-slip road will be closed each night during Phase One from Wednesday 10th September 2025. This closure will be in place overnight, between the hours of 8pm and 6am with a signed diversion in operation. Traffic will be instructed to continue on the M8 westbound and will exit via the Junction 26 off-slip road onto the Hillington Interchange, from here traffic will turn right onto Hillington Road. Traffic will then join King's Inch Road to be diverted right onto Old Govan Road, where diversion will end.
A 40mph speed limit will also be in effect during the project's duration, with average speed cameras in operation, ensuring the safety of the workforce and the travelling public as 24/7 construction work will take place. Overnight closures will be required for traffic management installation and changes as the project progresses; these will be communicated in advance on swtrunkroads.scot. Recovery vehicles will also be on-site.
Unfortunately, construction noise will be unavoidable for the duration of works. Suitable noise dampening measures will be implemented on-site overnight when undertaking works.
There is no passage for abnormal loads travelling in the eastbound direction between Junction 27 and 26. Abnormal Loads can travel westbound on the carriageway straddling the two available lanes.
Access for emergency service vehicles will be maintained throughout these works.
This scheme has been planned in consultation with Transport Scotland, Traffic Scotland, the emergency services, Renfrewshire Council, Glasgow City Council, West Dunbartonshire Council, and Braehead Shopping Centre.
Please note, all schemes are weather dependent and may be cancelled or rescheduled if weather conditions are not favourable.
Road users are thanked for their patience and understanding while this work is being undertaken. Advice is to allow for extra time to complete any journeys during this period, using alternative routes where possible. Various road network improvements are taking place across the M8 corridor through Glasgow and these should be considered in any journey planning.
Updates to this project including the commencement of each new phase will be communicated via swtrunkroads.scot.
