M27 junctions 11 and 12 near Fareham
We need to repair a section of the central reservation concrete safety barrier on the M27 near Fareham.
Expect delays - please allow extra journey time
We need to close the M27 in both directions between junctions 11 and 12 over two nights:
- 9pm Friday 21 March to 6am Saturday 22 March
- 9pm Sunday 23 March to 6am Monday 24 March
We need this closure to work safely and to allow time for concrete to harden.
We'll also need:
- eastbound and westbound lane closures in the daytime on Saturday 22 March and Sunday 23 March
- overnight lane closures on Saturday 22 March
There'll be a 50mph speed restriction during both daytime and overnight lane closures.
We're advising you to expect delays and allow extra time for your journey.
Diversion
We'll put a signed diversion in place by:
- A27 Portsbridge roundabout
- A27 Southampton Road/ M275 junction
- A27 Delme Roundabout
- A27 to M27 junction 11.
Please remember that closures can change at short notice. You can check the latest information on our daily closures page or find live travel information on our Traffic England. Our travel alerts give details of live incidents on our network.
