Horror Crash Closes M8 at White Cart Viaduct in Paisley
Two women have been rushed to hospital following a serious crash on the M8 motorway near Paisley, Scotland, after a car reportedly went over a bridge at the White Cart Viaduct. The incident occurred at approximately 8:40pm on Thursday evening, July 16, 2026, prompting the complete closure of the M8 westbound at Junction 27. Emergency services including Police Scotland, the Scottish Ambulance Service, and the Scottish Fire and Rescue Service responded to the scene of the single-vehicle crash, which has caused major disruption on Scotland’s busiest motorway.
Emergency Response at White Cart Viaduct
The crash at the White Cart Viaduct required a significant emergency response due to the nature of the incident and the location. The viaduct carries the M8 over the White Cart Water, and reports indicate the vehicle left the carriageway and went over the bridge structure. Emergency crews worked to reach the vehicle and extract the two women who were trapped inside. Both were transported to hospital for treatment, though the extent of their injuries has not been publicly disclosed. The complexity of the rescue operation at the viaduct added to the response time and required specialized equipment.
M8 Westbound Closure Causes Major Delays
Traffic Scotland confirmed that the M8 was closed westbound at Junction 27 (White Cart Viaduct) following the crash, with traffic being diverted off the motorway. The closure had an immediate impact on evening commuter traffic, with long queues building rapidly in the Paisley and Glasgow areas. Motorists were advised to use caution on approach to the scene and to expect significant delays. Traffic Scotland used its social media channels to keep the public updated on the closure and diversion routes, but the sudden nature of the incident meant many drivers were caught in the resulting congestion.
Recent M8 Crash History in Scotland
Thursday’s crash at the White Cart Viaduct is the latest in a series of serious incidents on the M8 in recent weeks. On July 11, six people including three children were taken to hospital after a crash involving a Mercedes Vito minivan and an HGV near Chapelhall. Police Scotland have been actively investigating that incident and appealing for witnesses. The frequency of serious crashes on Scotland’s main motorway artery has raised concerns about road safety on the M8, which carries tens of thousands of vehicles daily between Glasgow and Edinburgh.
Police Scotland Investigation
Police Scotland has launched an investigation into the circumstances surrounding the crash at the White Cart Viaduct. Officers are working to determine what caused the vehicle to leave the carriageway and go over the bridge. The road surface, weather conditions, vehicle factors, and driver behavior will all be examined as part of the investigation. Police have not yet indicated whether any other vehicles were involved in the incident. Officers are appealing for anyone who witnessed the crash or who may have dashcam footage from the area around Junction 27 to come forward.
