The A720 Edinburgh City Bypass has been closed in both directions between Dreghorn Junction and Hermiston Gait following a severe collision late Wednesday evening, triggering miles of gridlock and critical commuter delays across east-central Scotland this morning. Traffic Scotland and Police Scotland have confirmed the complete closure of the trunk route to allow crash investigation units to complete on-scene forensic assessments. The disruption has paralyzed key arterial corridors, backing up traffic across the M8, M9, and connecting commuter arteries heading into Edinburgh.
Transportation authorities are urging motorists across Edinburgh, the Lothians, and Fife to defer non-essential journeys or seek alternative routes. Surrounding secondary routes through Baberton, Clovenstone, Colinton, and Longstone are currently saturated, with peak-period transit times extending up to 60 to 90 minutes beyond typical schedules. Traffic monitoring feeds show queues trailing back to junction 2 on the M8 eastbound and heavy congestion snaking along the A70 and A71.
Destaques
- Full Highway Closure: A720 Edinburgh City Bypass remains shut both eastbound and westbound between Hermiston Gait and Dreghorn.
- Crash Investigation Underway: Emergency services and forensic collision officers have been working at the site since the incident occurred at approximately 8:55 PM on Wednesday.
- Massive Regional Impact: Severe queues stretch toward Livingston on the M8, with local diversion routes through Baberton, Clovenstone, and Colinton heavily bottlenecked.
- Reopening Indefinite: Police Scotland has advised that the road is expected to remain closed for several hours, with no immediate timeline confirmed for reopening.
What Caused the Edinburgh Bypass Closure?
According to updates released by Police Scotland and corroborated by live incident tracking from Traffic Scotland, emergency services were dispatched to the A720 Edinburgh City Bypass near Clovenstone and Baberton at approximately 8:55 PM on Wednesday, November 11, 2026. The collision involved multiple vehicles and prompted an immediate response from Police Scotland, the Scottish Ambulance Service, and the Scottish Fire and Rescue Service.
Due to the severity of the impact, specialist collision investigation units were deployed overnight. Standard operational protocol for major highway incidents in Scotland mandates a total road closure while investigators map the scene, collect forensic physical evidence, and clear vehicle debris. Because the incident scene spans multiple lanes across the carriageway, the decision was made to halt traffic in both eastbound and westbound directions between Dreghorn and Hermiston Gait to preserve public safety and forensic integrity.
Severe Traffic Delays and Key Congestion Hotspots
The closure of one of Scotland's most heavily traversed bypasses has displaced tens of thousands of peak-time vehicles onto urban bypass lanes and residential roads. Real-time sensor data from Traffic Scotland highlights severe delays across several key arteries:
- M8 Eastbound Approach: Queues approaching the Hermiston Gait roundabout stretch back past Junction 2 (Claylands) toward Newbridge, adding up to an hour to morning commuter journeys.
- A71 Calder Road & A70 Lanark Road: Inbound traffic attempting to skirt the southern bypass has created bumper-to-bumper conditions through Currie, Juniper Green, and Slateford.
- Southbound & Eastbound A720: Tailbacks heading westbound from Sheriffhall and Lothianburn reach past Dreghorn as vehicles are forced onto the single-lane off-ramps.
- Public Transit Disruption: Regional bus operators, including Lothian Buses and Scottish Citylink services between Glasgow and Edinburgh, report route diversions and major timetable variances.
Official Diversion Routes and Driver Advice
Traffic Scotland has activated strategic variable message signs across the national motorway network, alerting drivers on the M90, M8, and M9 before they reach Edinburgh outer limits. Motorists already en route are advised to follow the official signed diversions:
- Westbound Diversion: Traffic approaching Dreghorn is directed off the bypass via the B701 and onto local secondary routes toward the A70, looping north to reconnect with the A720 at Hermiston Gait or continuing inward to the Calder junction.
- Eastbound Diversion: Traffic coming off the M8 or the M9 at Hermiston Gait is diverted along Calder Road (A71) inbound toward city centre link roads or routed south via the A70 toward Balerno and Currie before rejoining at Dreghorn.
Transport officials strongly recommend that road users consult the Traffic Scotland website and monitor official social feeds (@trafficscotland) prior to travel. Where possible, commuters are encouraged to work remotely or utilize ScotRail passenger rail services, which are operating normal timetables between Glasgow, West Lothian, and Edinburgh Waverley.
