Edinburgh City Bypass Closure: Diversions and Delays on Nov. 12

Checked: Nov. 12, 2026, 9:05 a.m. GMT (UTC+00:00). Traffic Scotland lists the A720 Edinburgh City Bypass as closed in both directions between Dreghorn and Hermiston Gait following a police incident. The agency’s incident page, last updated at 8:00 a.m. GMT, estimates delays of about 12 minutes eastbound and 25 minutes westbound; it says the cause and expected duration are unknown. These are estimates, and conditions may have changed since the update.

Drivers approaching the affected stretch should follow the signed diversion and check Traffic Scotland’s live map or incident page before setting out. The official diversion uses local roads around the closure and, westbound, routes traffic toward Calder Junction and the M8 before Gogar Roundabout. No reopening time has been confirmed.

Where is the Edinburgh City Bypass closed?

Traffic Scotland places the closure on the A720 between Dreghorn and Hermiston Gait. Both eastbound and westbound traffic are affected. Its incident detail lists the closure start as 9:08 p.m. on Nov. 11, with the latest update at 8:00 a.m. on Nov. 12. It attributes the closure to a police incident but provides no further cause or expected duration.

The official listing gives estimated delays of approximately 12 minutes eastbound and 25 minutes westbound. Treat these as snapshots, not a guarantee of travel time: queues can grow or clear as traffic and emergency response change. The incident detail also lists specific junction slip closures as part of its diversion instructions, so drivers should follow the signs on the road rather than assume every usual entry or exit remains available.

What is the signed diversion route?

For westbound traffic, Traffic Scotland directs drivers leaving the A720 at Dreghorn Junction to take the slip to Dreghorn Link and continue to Redford Road. The signed route then uses Colinton Road, Bridge Road and Gillespie Road, crosses Gillespie Crossroads into Wester Hailes Road, continues through Clovenstone Roundabout and Murrayburn Road to Bankhead Roundabout, then follows Calder Road to Calder Junction. From there, the route joins the M8 northbound toward Gogar Roundabout.

For eastbound traffic, the agency says the closure affects the A720 eastbound off-slip for Hermiston Gait/A71 Calder Road and the eastbound slips from Calder Roundabout and Hermiston Gait Roundabout. Its listed diversion uses the A71 to Calders Roundabout, then Calder Road, following the westbound diversion in reverse. Junction approaches and temporary traffic arrangements can be complex, so follow local signs and instructions from police or road staff. Do not make a last-minute turn or stop in a live lane to follow a navigation-app reroute.

How could the closure affect my journey?

The bypass connects routes around the south and west of Edinburgh, so a closure across this section can affect trips that would otherwise pass between the A702/Dreghorn side and Hermiston Gait, the M8 or the A71. Detoured vehicles share local roads and junctions, which may slow journeys beyond the agency’s estimates, particularly if traffic builds at roundabouts or approaches to the diversion. This is a practical possibility, not a confirmed forecast of additional delay on any particular road.

If your trip is flexible, consider waiting for a fresh update or choosing a route that avoids the closed section. If you must travel, allow extra time, keep fuel or battery range in mind, and check the route again before departure. For a destination within Edinburgh, a route through the city may be an option depending on your origin and destination, but it is not a universal substitute: check live routing and restrictions rather than diverting through residential streets. Drivers unfamiliar with the local road network should use the signed diversion.

When will the A720 reopen?

Traffic Scotland currently lists the expected duration as unknown. The page does not confirm a reopening time, and the available official information does not explain the incident beyond identifying police involvement. Do not rely on an estimated clearance time from an unofficial post.

For the latest status, revisit Traffic Scotland’s current incidents page and its live traffic map before you leave and during a safe stop. The City of Edinburgh Council travel page points readers to Traffic Scotland for trunk-road and City Bypass updates.
