Amey, on behalf of Transport Scotland, is undertaking essential refurbishments of the Cornwall Street and Kirkwood Street footbridges that span the M8 between Junction 21 (Seaward Street) and Junction 23 (Dumbreck), to the south-west of Glasgow city centre.
 
To allow the bridge spans to be safely lifted back into place, two extended overnight closures are required across the M8, in both directions, between Junctions 19 (Anderston) and 24 (Helen Street) in November 2026.
 
Road users are advised to avoid travel through this location and should plan ahead, consider alternative routes and modes of transport, and allow additional time to complete any journeys.
 
Signed diversion routes will be in place, and the programme of extended overnight closures is as follows: 
  • Weekend Two (Cornwall Street Span Reinstatement): 6pm on Saturday 14th November until 1pm on Sunday 15th November 2026

Traffic will be diverted via Helen Street, Edmiston Drive, Paisley Road West, Paisley Road, Kingston Street, Commerce Street, Broomielaw, and the A804, before joining the M8 eastbound at Junction 19.

Are there likely to be severe delays on diversion routes?

Road users are strongly advised to avoid the area during the closures, with significant delays anticipated across the surrounding road network and diversion routes.
 
During similar closures in 2024, delays of up to one hour were experienced, and comparable delays are possible if traffic levels are not significantly reduced. Drivers are advised to consider alternative routes and modes of transport or avoid travelling through the area wherever possible.

What will happen if there are adverse weather conditions at the weekend?

This operation requires large cranes and specialist heavy lifting equipment and can only proceed in suitable weather conditions. Should high winds, heavy rainfall, or other forecast adverse weather make it unsafe to proceed, the works may be postponed or rescheduled at short notice.
 
To minimise the impact of any delay, a contingency weekend closure has been identified and may be used if the planned works cannot proceed as scheduled above. This contingency date is provided in advance for awareness only and will only be implemented if required:
 
Contingency Weekend: 6pm on Saturday 21st November until 1pm on Sunday 22nd November 2026.
