Motorists heading through Thornton Heath were warned to expect significant delays this afternoon after a crash shut Selhurst Road, with traffic queuing between The Crescent and Dagnall Park.
The collision closed the south London road in the middle of the afternoon rush, and diversions were quickly put in place. Bus routes 75 and 157 were both caught up in the disruption, with passengers warned to expect delays on services through the area.
This is a developing story. Our live updates follow the closure as it unfolds.
Drivers were being urged to avoid the area if possible and to allow extra time for any journey through the Thornton Heath area. Traffic was already building by mid-afternoon, with the closure adding pressure to surrounding routes as motorists looked for a way around the blocked stretch.
What drivers need to know
With Selhurst Road shut between The Crescent and Dagnall Park, the immediate impact is being felt across the local road network. The 75 and 157 bus routes, which run through the affected section, are on diversion — and anyone relying on them should expect disruption through the afternoon and into the evening peak.
Motorists planning to travel through south Croydon this evening would do well to check traffic conditions before setting off, allow extra time, and consider alternative routes around Thornton Heath rather than risking the queue. Delays of this kind can take some time to clear even after a road reopens, as traffic that has built up works its way through.
Selhurst Road is a busy corridor linking Thornton Heath with the Selhurst area, and any closure there ripples outwards — particularly onto the surrounding residential streets, which often take the strain when drivers look for rat-runs. Those streets are generally not built for heavy through-traffic, so delays can spread quickly.
Advice for bus passengers
For anyone who usually travels through the area by bus, the diversions on the 75 and 157 are the most immediate problem. When routes are diverted at short notice, stops closest to the closure are usually skipped and buses can run noticeably late, so checking live departure information before leaving is worth the effort.
Passengers may find it quicker to walk to a stop on an unaffected stretch, or to use an alternative route that avoids the closed section entirely. Transport for London’s travel tools and journey planner carry the latest diversion information, and allow extra time for connections if the closure is still in place during the evening peak.
How long do these closures last?
How long Selhurst Road stays shut will depend on what is found at the scene. A straightforward recovery can be done in a couple of hours, but if the collision is serious the road can stay closed for much longer — police collision investigators sometimes need to examine the carriageway in detail, measuring braking marks and debris before anything is moved.
Once the vehicles have been recovered and any damage to street furniture repaired, the road is usually reopened in stages, with traffic officers managing the flow until the backlog clears. Even then, residual delays are common: the queue that built up during the closure has to work its way through, and diverted traffic can take a while to disperse.
A day of disruption on the roads
The Thornton Heath closure comes on an afternoon of significant transport disruption across London. Earlier in the day, a crash closed London Road in Mitcham in both directions, with multiple bus routes diverted there as well, while a fire alert partly shut Stratford International station and a fire incident in Penge closed Thicket Road.
Road closures after collisions typically stay in place while emergency crews deal with the scene and make the carriageway safe again. In some cases the road remains shut while investigators examine what happened, particularly if there is any question about how the crash occurred.
No details have yet been released about any casualties, and no reopening time for Selhurst Road has been announced. We will continue to follow this story as more information becomes available.
