Glasgow M8 Woodside viaduct repairs face £152m price tag and no firm completion date

A prolonged repair programme on the M8 Woodside viaducts in Glasgow has been under construction for more than five years. Temporary works intended to stabilise the 50‑year‑old concrete structures have cost taxpayers £125 million so far, far exceeding the original £34 million budget and the 2023 completion target.

The Scottish Government now estimates the final bill will be between £126 million and £152 million, with a hoped‑for finish in the second half of 2027 but no precise date given. Labour MSP Paul Sweeney called the scheme a “colossal financial drain on the public finances,” while Transport Secretary Stephen Flynn has been urged to provide clarity as commuters endure frequent tailbacks on Scotland’s busiest motorway.
