A27 Closure West Sussex: Live Traffic Updates and Diversions

 

The A27 closure in West Sussex has triggered serious delays for motorists, commuters, and businesses, following an incident that prompted police to shut the major dual carriageway in both directions between Emsworth and Chichester. This stretch of road is part of a crucial transport corridor across the south of England, and the disruption has prompted concerns among travellers who rely on it daily.

So what’s actually going on with the A27, how can you plan your journey around it, and where can you find live updates? Here’s everything you need to know including diversion details, safety tips, and the wider impact of the closure.

What Is Causing the A27 Closure in West Sussex?

The A27 was closed on Monday 26 January 2026 after Sussex Police responded to a serious ongoing incident between the A259 junctions at Emsworth and Chichester. The police, along with National Highways, closed the road in both directions around 05:40 GMT.

Reports indicate that the closure was due to concerns for a person’s welfare. While further details were not released, emergency response protocols necessitated a complete closure of both carriageways while responders dealt with the situation.

How Long Will the A27 Closure Last?

There is no confirmed reopening time, as closures linked to live police incidents remain in place until the situation is resolved. Depending on the nature of the incident, closures can last several hours, particularly if forensic investigations or safety checks are required.

Motorists should continue to check live traffic updates and avoid the area unless travel is essential.

How Is the A27 Closure Impacting Local Travel and Businesses?

The A27 supports thousands of daily commuters, commercial hauliers, public services, and local delivery drivers. The sudden closure has caused:

• Severe morning and evening traffic delays
• Route disruptions for buses and taxis
• Increased congestion in Chichester, Emsworth, and adjacent areas
• Knock-on effects on train stations and park-and-ride services

A local delivery company driver from Chichester said, “We’ve had to completely re-route all jobs eastbound. We’re now 40 minutes behind every delivery.”

 Can You Take Public Transport Instead of Driving?

For some journeys in West Sussex, public transport can be a convenient alternative to driving during the A27 closure. If your travel is local, consider the following options:

• Southern Rail Services: Trains running between Havant, Emsworth, and Chichester can help you bypass the busiest road sections. Check live timetables in advance, as services may be affected by engineering works or high passenger volumes during peak times.
• Local Bus Routes: Many bus services operate on routes that avoid the A27 directly. Using buses can save you the stress of navigating congested diversion routes, but be aware that some bus journeys may still face minor delays due to traffic on surrounding local roads.
• Park-and-Ride Options: Around Chichester, park-and-ride facilities offer a flexible way to combine driving and public transport. You can park your vehicle at designated lots and continue your journey by bus, reducing congestion and avoiding road closures. Check the West Sussex County Council website for updates on service changes, operating hours, and availability.

While public transport is a practical alternative, it’s important to plan ahead. Some routes may still experience delays or diversions if local roads are congested due to the closure. Monitoring live updates from transport providers can help you make timely adjustments and ensure a smoother journey.

 What You Should Do to Stay Safe While Driving During the Closure?

If you’re travelling in or around West Sussex during the A27 closure, it’s important to prioritise safety and plan ahead. Follow these tips to reduce risks and ensure a smoother journey:

• Avoid the A27 between Emsworth and Chichester: The closed section is prone to heavy congestion and delays. Using alternative routes or avoiding travel in peak hours can save time and reduce stress.
• Follow official diversion signs: Stick to the officially marked diversions rather than taking shortcuts. Unfamiliar side roads may be narrow, poorly lit, or not designed to handle high traffic volumes.
• Leave early and allow extra time: Factor in delays when planning your journey, especially during peak hours or if you have appointments. Rushing can lead to unsafe driving decisions.
• Keep fuel levels topped up: Ensure your vehicle has enough fuel in case you get stuck in traffic. Additionally, have a phone charger on hand if you rely on GPS navigation to avoid being stranded without directions.

Be aware that local roads, such as the A259 and surrounding B-roads, are likely to see significantly higher traffic volumes. These roads may not be designed for extended congestion, may have poor lighting at night, and could present unexpected hazards. Staying alert, driving cautiously, and maintaining safe following distances is key to navigating these conditions safely.
