M8 Junction 19 Waterloo Street On Slip | Investigations and Repair

Amey, on behalf of Transport Scotland, is undertaking essential bridge investigations of the M8 Kingston Bridge Complex from Monday 18th May until Saturday 13th June 2026. The main body of works requiring closure of the M8 Junction 19 Waterloo Street on-slip road will take place from Sunday 24th May until Tuesday 9th June 2026.

Waterloo Street On-Slip Road Closure

A total closure of the M8 Junction 19 Waterloo Street on-slip road will be in place, on a 24/7 basis, from Sunday 24th May until Tuesday 9th June 2026.

Traffic intending to use the Waterloo Street on-slip road will be diverted onto West Campbell Street, St Vincent Street, and Newton Street. From here, traffic will be able to join the M8 westbound via the Newton Street on-slip road.

On the nights of Sunday 24th May through to Friday 29th May an alternative diversion route will be in place between the hours of 9pm and 6am with traffic intending to use the Waterloo Street on-slip road, including selected bus services, will be diverted onto Pitt Street, Bothwell Street, Wellington Street, Broomielaw, Bridge Street/Eglinton Street, Nelson Street, Paterson Street, Wallace Street, and Dalintober Street. From here, traffic will be able to join the M8 westbound.

Bus Services

Throughout the Waterloo Street on-slip road closure, services that use the bus stop located at the bottom of Waterloo Street will be closed and temporarily re-located to the existing bus stop to the east of its junction with West Campbell Street. These bus services will be diverted to turn right onto Pitt Street through St Vincent Street, and Newton Street to then join the M8 westbound via the Newton Street on-slip road, except when the alternative diversion route is in place on the nights of Sunday 24th May through to Friday 29th May.

Bus services that use the bus stop located between Blythswood Street and West Campbell Street will be closed and temporarily re-located to West Campbell Street. These bus services will continue onto West Campbell Street, St Vincent Street, and Newton Street. From here, traffic will be able to join the M8 westbound via the Newton Street on-slip road, except when the alternative diversion route is in place on the nights of Sunday 24th May through to Friday 29th May.

Please contact affected bus operators for further information on how their services will be impacted. Coach bus services will follow the standard signed diversion route.

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.  

Please note, all schemes are weather dependent and may be cancelled or rescheduled if weather conditions are not favourable.
