National Highways reminds drivers of upcoming A27 closures for maintenance work
Reminders issued as road closures will be in place this weekend
Diversion routes will be in place this weekend as essential maintenance work is completed on the A27.
National Highways has confirmed multiple dates where closures will be in effect on the westbound carriageway of the A27 at Langstone. This comes after engineers were expected to undertake improvement work over the last weekend of September, but they had to abandon the proposed maintenance due to two road traffic incidents.


The upcoming repairs are part of Langstone Interchange bridge safety work and will extend the life of both bridges, improve safety for road users, and significantly reduce the noise caused by the ageing deck joints.
The project is part of a wider investment along the A27 to future-proof the busy stretch of road so it remains a safe and reliable route for many years to come.
The closures are as follows:
Weekend:
- Saturday, October 17 at 9pm to 6am on Monday, October 19 - A27 westbound from Emsworth (Warblington) to Langstone
Weekday Overnight Closures:
- Between 8pm and 6am - Monday, October 12 to Friday, October 16 – A27 Langstone interchange westbound
- Between 8pm and 6am - Monday, October 19 to Friday, October 23 – A27 Langstone interchange westbound
Diversion routes will be in place - for more information, click here.
