Key Points
- All 16 lanes of the M8 motorway in south-west Glasgow will close from 6pm on Saturday, 14 November 2026, until 1pm on Sunday, 15 November 2026.
- Amey is carrying out the essential refurbishment works on behalf of Transport Scotland to reinstate the refurbished bridge span of the Cornwall Street footbridge, following last weekend’s work on the Kirkwood Street footbridge between Junction 21 and Junction 23.
- Eastbound closures will span between Junction 24 (Helen Street) and Junction 22 (Plantation), while westbound closures will run between Junction 20 (West Street) and Junction 24, alongside knock-on effects for parts of the M77 and M74.
- Transport Scotland and Amey SW Trunk Roads have warned motorists to expect “significant delays” of up to one hour on diversion routes and advised avoiding the area or using alternative modes of transport.
- The operation requires large cranes and specialist heavy lifting equipment and remains weather dependent, meaning adverse weather conditions could force a postponement at short notice.
- Drivers leaving the signed diversion routes risk incurring penalty charges from Glasgow City Council, particularly in relation to Glasgow’s Low Emission Zone.
- Events potentially affected by the travel disruption include the Beabadoobee concert at the OVO Hydro on Saturday and fans travelling from Glasgow for Scotland’s rugby match against Australia at Murrayfield.
Glasgow (Glasgow Express) November 2026 – Motorists travelling through Glasgow this weekend have been warned to expect “significant delays” as all 16 lanes on a major stretch of the M8 motorway close in both directions for essential footbridge refurbishments.
Why Is the M8 Closing This Weekend?
The complete weekend closure is required to allow engineers to safely lift and reinstate the refurbished concrete span of the Cornwall Street footbridge across the motorway.
As reported by the Express & Star, Amey is carrying out the work on behalf of Transport Scotland on the Cornwall Street and Kirkwood Street footbridges between Junction 21 and Junction 23 to the south-west of Glasgow city centre. According to announcements from Amey SW Trunk Roads, the operation follows last weekend’s closure between 6pm on Saturday, 7 November, and 1pm on Sunday, 8 November, during which crews completed the reinstatement of the Kirkwood Street bridge span.
As reported by Matthew Fulton of STV News, all 16 lanes of the M8 will be shut to traffic to accommodate the complex engineering operation, which relies on large cranes and specialist heavy lifting equipment. STV News noted that Amey SW Trunk Roads confirmed the lifting procedures can only take place in suitable weather conditions, adding that should adverse weather make it unsafe to proceed, the works may be postponed or rescheduled at short notice.
When and Where Will the M8 Closures Be in Place?
The motorway shutdown will run continuously for 19 hours from 6pm on Saturday, 14 November 2026, until 1pm on Sunday, 15 November 2026, affecting both carriageways and neighbouring motorways.
As reported by Callum McCormack of The Scotsman, eastbound traffic on the M8 will be closed off between Junction 24 (Helen Street) and Junction 22 (Plantation). On the westbound carriageway, closures will stretch from Junction 20 (West Street) to Junction 24. In its official scheme update, Amey SW Trunk Roads specified that the broader operational footprint for the overnight lifting works encompasses the M8 in both directions between Junction 19 (Anderston) and Junction 24 (Helen Street), alongside associated slip-road restrictions and impacts on adjoining sections of the M77 and M74.
Are Diversions in Place for the M8 Closures?
Signed diversion routes will operate throughout the 19-hour shutdown, though motorists using them are warned to anticipate severe delays of up to one hour.
As reported by Callum McCormack of The Scotsman, Transport Scotland has urged drivers to allow extra time for their journeys and follow the official diversions. Motorists affected by the closures will be diverted via Helen Street, Edmiston Drive, Paisley Road West, Paisley Road, Kingston Street, Commerce Street, Broomielaw, and the A804, before rejoining the M8 eastbound at Junction 19.
As reported by the Glasgow Times, local authorities have cautioned drivers against straying from the designated diversion paths. The Glasgow Times noted that drivers who leave the signed diversion route risk incurring penalty charges issued by Glasgow City Council, which enforces Glasgow’s Low Emission Zone (LEZ) in the city centre. Both Transport Scotland and Amey SW Trunk Roads have advised road users to avoid travelling through this section of Glasgow altogether where possible, or to consider alternative modes of transport.
What Events Could Be Affected by the M8 Closures?
Major live music and international sporting fixtures taking place across central Scotland risk being disrupted by congestion on surrounding roads.
As reported by Callum McCormack of The Scotsman, concertgoers heading to Glasgow’s OVO Hydro on Saturday evening for Beabadoobee’s Powerlines Tour performance could encounter delays approaching the venue. The Scotsman also reported that rugby supporters travelling from Glasgow ahead of Scotland’s international fixture against Australia at Murrayfield, scheduled for a 3.10pm kick-off, may experience disruption on connecting routes. Additionally, Glasgow Airport and local event venues have issued travel advisories urging passengers and attendees to factor potential motorway delays into their schedules.
Background of the Development
The Cornwall Street and Kirkwood Street footbridges are approximately 50-year-old concrete structures spanning the M8 corridor between Junction 21 (Seaward Street) and Junction 23 (Dumbreck). Under a major infrastructure maintenance programme commissioned by Transport Scotland, contractor Amey removed the suspended concrete bridge spans in the summer of 2024 so they could undergo extensive off-site structural refurbishment.
According to project documentation published by Amey SW Trunk Roads, the engineering scope includes waterproofing and resurfacing the bridge decks, replacing expansion joints and bearings, installing new pedestrian parapets, carrying out concrete repairs with cathodic corrosion protection, and strengthening half-joint locations. Following site re-mobilisation in August 2026 and preparatory weekday overnight lane restrictions, the two November weekend closures were scheduled to lift the refurbished spans back into position. Once both spans are reinstated and final finishing works are completed, the footbridges are scheduled to reopen to pedestrians and cyclists in February 2027.
Prediction: How This Development Will Affect Glasgow Road Users and Commuters
For motorists, freight operators, and weekend travellers in west-central Scotland, the immediate impact of the 19-hour closure will be heavy congestion across south-west Glasgow’s local road network, particularly along Paisley Road West, Helen Street, and the Clyde crossings as all 16 lanes of motorway traffic funnel onto urban streets. Drivers unfamiliar with the city’s Low Emission Zone boundaries face an elevated risk of financial penalties if they deviate from the official signed diversions into restricted city-centre streets.
In the medium to longer term, however, the successful reinstatement of the Cornwall Street span marks a decisive milestone toward ending more than two years of lane restrictions, slip-road closures, and pedestrian diversions between Junctions 21 and 23. Once the remaining deck finishing and safety inspections conclude ahead of the February 2027 reopening, local residents and active-travel commuters in Kinning Park, Plantation, and Dumbreck will regain direct, traffic-free pedestrian and cycle links across the M8, while motorway users will benefit from structurally reinforced crossings designed to prevent unplanned emergency closures for decades to come.
