A23 Northbound Closed After Single-Vehicle Crash and Diesel Spill

A section of the A23 northbound has been closed following a single-vehicle collision that resulted in a diesel spill across three lanes, causing significant traffic disruption.

The incident occurred between the A272 (Bolney) and the B2115 (Cuckfield) earlier today, leading to the closure of the northbound carriageway as emergency services and specialist contractors work to clear the scene.

Diesel Spill Causes Major Disruption

The vehicle involved in the collision spilled a considerable amount of diesel fuel across all three lanes of the A23 northbound, prompting authorities to close the road to prevent further accidents.

A spokesperson for National Highways stated:
“Due to the extent of the diesel spill, the northbound carriageway between Bolney and Cuckfield has been fully closed. Specialist clean-up crews are en route to assist with the removal of the hazardous material and ensure the road surface is safe for travel.”

Emergency services, including Sussex Police and fire crews, are on the scene. No serious injuries have been reported as a result of the collision.

Traffic Delays and Diversions

Significant traffic delays are building in the area, with congestion stretching several miles back towards the A2300 junction. National Highways has advised drivers to avoid the area if possible and seek alternative routes.

A diversion has been put in place:

  • Northbound traffic is being directed off the A23 at the A272 (Bolney) junction, with routes leading through Ansty and Cuckfield to rejoin the A23 further north.

Motorists are urged to follow official diversion signs and allow extra time for their journeys.

Safety Precautions

Authorities have emphasized the risks associated with diesel spills, which can create extremely slippery conditions for both cars and motorcycles.

“Diesel on the road poses a significant hazard, especially in wet conditions,” said the National Highways spokesperson. “We are working as quickly and safely as possible to clean the spill and reopen the road.”

When Will the A23 Reopen?

At this time, there is no estimated reopening for the A23 northbound. Clean-up operations are expected to take several hours, as specialist contractors will need to treat the road surface to ensure it is safe for use.

Drivers are encouraged to monitor traffic updates via National Highways and local news outlets for the latest information on road closures and reopening timelines.

Public Reaction

Local residents and commuters have expressed frustration over the unexpected delays but have also acknowledged the importance of safety in such situations.

“It’s frustrating, but I’d rather they take the time to clean it properly than risk more accidents,” said a commuter caught in the delays.
