Edinburgh (Edinburgh Daily) July 10, 2026, that a crash on the A720 City Bypass caused significant delays for westbound traffic, with the incident first logged at about 2.41pm. The collision involved two vehicles, and emergency services were in attendance at the scene. Police Scotland said the bypass was closed westbound at Dreghorn Junction following the crash around 2.40pm.
The disruption quickly spread beyond the immediate crash site, with long tailbacks forming along the westbound carriageway. Traffic Scotland said one lane was restricted westbound between Baberton and Calder, while drivers were also facing delays in other parts of the route. The road is a key commuter artery around the city, so even a short closure can affect several junctions at once.
How bad were the delays?
As reported by Edinburgh Live, motorists heading on to the bypass were warned to expect heavy delays as traffic backed up between Calder and Baberton. Further congestion was also reported at Lothianburn and between Lasswade and Gilmerton Junctions, showing how quickly the incident affected wider traffic flow. Another Edinburgh outlet reported that queues were becoming substantial, with delays measured at more than 70 minutes in some areas.
The exact impact on individual drivers would have depended on where they joined the bypass and whether they were travelling westbound or approaching from feeder roads. However, the overall picture was one of slow-moving traffic and restricted movement across a major section of the road. With emergency services on site, traffic management and clearance work would have taken priority before the full reopening.
What did officials say?
Traffic Scotland’s update said there was an accident on 10 July at 2.41pm on the westbound A720 between Baberton and Calder, with one lane restricted. Police Scotland said the A720 Edinburgh City Bypass was closed westbound at Dreghorn Junction after a two-vehicle crash at about 2.40pm on Friday, 10 July. Those statements confirmed both the location and the direction most affected by the incident.
No immediate detail was released about injuries or the condition of those involved. That meant the public information at the time focused mainly on route closure, delays, and traffic management rather than personal outcomes. In road incidents like this, authorities usually update the public again once the scene is cleared and the road can be reopened safely.
Why the bypass matters?
The A720 Edinburgh City Bypass is one of the city’s most important transport routes, connecting several major junctions around Edinburgh. Because it carries a large volume of commuter and cross-city traffic, even a single-lane restriction can create wider congestion across nearby roads. Friday afternoon traffic can also intensify the effect, as more drivers are already on the network.
In practical terms, this kind of disruption can affect school runs, business travel, deliveries, and onward journeys to neighbouring areas. It can also push traffic on to alternative roads that are not designed to absorb large volumes for long periods. That is why official warnings often urge drivers to avoid the area where possible.
Background of the development
The latest crash adds to a pattern of recurring disruption on the Edinburgh bypass, which regularly features in traffic alerts because of its importance to the city’s road network. Previous incidents on the A720 have also led to full or partial closures, long queues, and delays for motorists travelling through key junctions such as Baberton, Dreghorn, Sheriffhall, and Old Craighall. This makes the bypass a frequent pressure point whenever an accident occurs.
Prediction for drivers
For commuters and local motorists, this incident is likely to reinforce the need to allow extra travel time whenever travelling on the A720, especially during afternoon peak hours. If crashes or lane restrictions happen again, delays are likely to spread quickly across feeder routes and nearby junctions. For businesses and delivery services that rely on punctual movement around Edinburgh, even short disruptions on the bypass can affect schedules, fuel use, and route planning.
