M8 Hillington Phase Three | Major Bridge Refurbishment Works

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 THREE

Phase Three will take place from Monday 5th January until Saturday 31st January 2026 under Lane Three closures on both the eastbound and westbound M8 mainline carriageway. Total closure of the eastbound carriageway (overnight only) on Monday 5th January 2026 and westbound (overnight only) on Tuesday 6th and Wednesday 7th January 2026 will be required to complete the change in traffic management.

From Thursday 8th January until Sunday 11th January 2026 (overnight only), a total closure of the westbound M8 Jct 26 mainline between the slip roads will be installed, with diversion as follows:

M8 Jct 26 WB off slip - M8 Jct 26 WB on slip - Diversion end

From Monday 12th January until Saturday 31st January 2026 (overnight only) a full closure of the eastbound mainline will be installed, lanes 2 and 3 in the westbound direction will also be closed to allow completion of the Phase 3 works. Diversion for eastbound closure is as follows:

M8 Jct 26 EB off slip - M8 Jct 26 EB on slip - Diversion end

Please note, the 2+2 contraflow that has been in place since September 2025 will be removed as traffic management moves to lane closures for this phase, but this will be installed again for phase 4.

Overnight closures of the M8 Junction 26 eastbound on-slip road will also be required from 10pm until 6am on Monday 2nd February to Sunday 8th March 2026.

During these overnight closures, traffic will be diverted as follows:

North of Hillington Interchange for Vehicles in Renfrew/Braehead Area:

Overnight traffic wishing to use the Junction 26 on-slip road will be directed to follow Hillington Interchange to Renfrew Road, Shieldhall Road, and Helen Street to join the M8 eastbound at the Junction 24 (Helen Street Interchange) on-slip road.

South of Hillington Interchange for vehicles in Hillington Industrial Estate area:

All traffic wishing to use Junction 26 from south of the Interchange will be directed to follow Hillington Road to Paisley Road West, Helen Street, and then join the M8 eastbound via Junction 24 (Helen Street Interchange) on-slip road.

Please note the majority of the works being undertaken in Phase 3 will be carried out overnight with minimal works happening during daytime hours. This is to ensure the safety of road users and road workers and also to minimise disruption to road users.

A 40mph speed limit remains in effect throughout 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.

Since the commencement of this project, reported delays for road users have been negligible outwith typical congestion on this section of the M8 during AM and PM commuter peaks.

Retail outlets in the Hillington area, including Braehead Shopping Centre, will be operating as normal with trading hour details available from their associated websites and social media channels. Any road closures required have been planned with a later start time to mitigate disruption to shoppers.

Unfortunately, construction noise will be unavoidable for the duration of works. Suitable noise dampening measures will be implemented on-site overnight when undertaking works.

During this phase abnormal loads can travel in both directions between Junction 27 and 26.

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.
