M8 motorway repairs in Glasgow to last for another two years

Major roadworks on the M8 motorway in Glasgow city centre are scheduled to last for another two years, it has been announced.

Temporary repairs to the Woodside Viaduct, near Charing Cross, have already been taking place for more than four years.

The works have led to the busy motorway – used by 150,000 people a day – being narrowed from four lanes to two, with some slip roads closed.

The completion date – already pushed back several times – has now been delayed until the second half of 2027.

Amey contractors, appointed on behalf of Transport Scotland, are working to repair structures that hold up the viaduct after a 2021 inspection revealed they were in much worse condition than anticipated.

The repairs were originally due to be finished in late 2023.

Transport Scotland said the project had been complicated by the proximity of subway tunnels and, more recently, the discovery of a sewer in an unexpected position.

The works are expected to cost between £126m and £152m.

Transport Scotland said it was working to finish the repairs “as quickly and safely as possible”.

Director of major projects Lawrence Shackman said: “The project has been continuously hampered by inaccurate records of utility apparatus as well as the recent discovery of an uncharted sewer buried deep underground leading to delays and additional work.

“Amey continues to face significant challenges, and the latest information now indicates an anticipated date for full completion of the work allowing traffic management to be removed in the second half of 2027.

“Due to the nature of the work, they are continuing to work towards opening the eastbound carriageway in autumn 2026.”
