A23 southbound has been closed in West Sussex following a fuel spillage caused by an earlier incident involving a broken-down heavy goods vehicle, with motorists facing significant delays and congestion.
The closure is affecting the A23 between the A273 at Pyecombe and the A2300 at Hickstead, according to the latest update from National Highways. Sussex Police and National Highways teams are at the scene while the spilled fuel is treated and the carriageway is made safe.
The disruption has prompted drivers to search for the latest information about the A23 accident today, the southbound closure, traffic queues and possible alternative routes.
A23 Southbound Closed in West Sussex
National Highways confirmed that the A23 is currently closed southbound between the A273 at Pyecombe and the A2300 at Hickstead.
The closure is required because of a fuel spillage following an earlier breakdown involving a heavy goods vehicle.
Specialist teams are working to treat the affected section of road before traffic can safely return to normal.
Sussex Police and National Highways’ area team are both attending the incident. Motorists have been warned to expect delays and are being advised to consider changing their route where possible.
The affected stretch is an important route through West Sussex, meaning a full southbound closure can quickly create congestion on surrounding roads.
What Happened on the A23?
The current disruption follows an earlier incident involving a broken-down HGV.
A fuel spill occurred on the southbound carriageway, requiring the road to be closed while crews deal with the contamination.
Fuel spilled onto a busy road can create a serious safety hazard because it can reduce the grip available to vehicles and increase the risk of further collisions.
For that reason, the priority is to treat and clean the affected surface before the carriageway is reopened.
National Highways has confirmed that the closure is directly related to the fuel spillage and that teams are working at the scene.
Where Is the A23 Closed?
The closure covers the southbound A23 between:
- A273 at Pyecombe
- A2300 at Hickstead
National Highways describes the affected section as a carriageway closure with delays expected.
Traffic is being diverted using local routes while the fuel spill is dealt with.
Drivers heading toward Brighton are likely to be particularly affected because the southbound A23 is a major route into the city and surrounding areas.
The closure also has the potential to place additional pressure on nearby roads as motorists attempt to avoid the affected section.
Traffic Delays and Queues
The closure has resulted in significant congestion in the area.
A local traffic report said queues had extended back toward the A272 Cowfold Road at Bolney Cross, highlighting the wider impact of the incident.
Motorists traveling south should therefore expect journey times to be considerably longer than normal.
Even after the road is reopened, traffic may take time to return to normal because vehicles that have been delayed will continue moving through the area.
Drivers are advised to check conditions before beginning their journey and allow additional time.
A23 Accident Today: Is the Road Still Closed?
The latest National Highways information confirms that the A23 southbound remains closed between the A273 and A2300 while the fuel spillage is treated.
There is no indication in the current update that the southbound carriageway has fully reopened.
Because this is a live road incident, the situation can change as soon as the cleanup operation is completed.
Motorists should therefore avoid relying on older reports or social-media posts that may no longer reflect the current road conditions.
National Highways recommends checking live travel information and considering an alternative route or delaying travel where appropriate.
Emergency Crews Working to Make the Road Safe
The response involves both Sussex Police and National Highways’ area team.
Their work includes managing the closure, protecting road users and dealing with the fuel contamination.
Before the road can reopen, crews need to ensure that the surface is safe for traffic.
Fuel spills can leave a hazardous residue on the road, even after the visible liquid has disappeared.
The cleanup process is therefore an important part of restoring safe driving conditions.
Drivers Advised to Avoid the Area
Drivers who normally use the A23 southbound through West Sussex are being advised to avoid the affected section where possible.
National Highways has recommended that motorists allow extra journey time and consider rerouting or delaying their journey if the closure affects their plans.
This advice is particularly relevant during busy travel periods, when even a short closure can result in lengthy queues.
Drivers should also avoid attempting to pass through closed sections or entering areas where emergency crews are working.
Following diversion signs and instructions from traffic officials helps keep both motorists and emergency workers safe.

Why Fuel Spillage Can Cause a Full Road Closure
A fuel spill may appear relatively minor compared with a major collision, but it can create significant dangers for passing traffic.
Liquid fuel on the road can make the surface slippery and reduce vehicle control.
The affected area must therefore be treated before normal traffic can safely resume.
A full closure also gives emergency and maintenance crews enough space to work without having vehicles passing through the contaminated area.
This can mean that a road remains closed after the original vehicle breakdown has been dealt with.
In the case of the A23, the ongoing issue is the fuel spillage and the work required to make the carriageway safe.
A23 Traffic Toward Brighton
The A23 is an important route for motorists traveling south toward Brighton and other parts of the Sussex coast.
As a result, a closure between Hickstead and Pyecombe can affect commuters, commercial drivers and other travelers.
Drivers who would normally use the A23 should check their planned route before setting off.
Local diversion routes may also become busy as more motorists leave the main road to avoid the closure.
Allowing additional travel time can help reduce the pressure created by unexpected delays.
No Further Details About Injuries Released
The current National Highways update focuses on the road closure and fuel spillage.
It does not provide information about any injuries or fatalities connected with the original HGV incident.
Consequently, no claims about injuries should be treated as confirmed unless they are released by Sussex Police, emergency services or another authoritative source.
The immediate priority remains treating the spill and reopening the road safely.
Further information may become available as the response continues.
Investigation and Road Safety
The circumstances surrounding the original HGV breakdown and subsequent fuel spillage may be examined as part of the response.
At this stage, there is not enough information to determine whether another vehicle was involved or whether any particular factor caused the incident.
Drivers should avoid speculation until authorities provide additional details.
The closure itself is a precaution intended to protect motorists while crews work on the affected section.
How Long Will the A23 Closure Last?
A precise reopening time has not been provided in the latest National Highways update.
The road will need to remain closed while the fuel spill is treated and the carriageway is considered safe.
The length of the cleanup can depend on the amount of fuel spilled, the area affected and the work required to restore the road surface.
Motorists should therefore check for updated information before traveling.
National Highways’ live travel information can provide the latest status as the incident develops.
What Drivers Should Do
Motorists approaching the affected area should:
- Avoid the closed southbound section where possible.
- Follow signed diversion routes.
- Allow extra time for their journey.
- Check live traffic conditions before setting off.
- Follow instructions from police and traffic officers.
- Do not attempt to drive through barriers or closed sections.
- Remain alert for congestion on surrounding roads.
Drivers should also remember that delays can continue after a closure has been lifted because queues take time to clear.
