High levels of traffic using J11 are causing delays.

Widening work aims to increase capacity.

Installation of a signal-controlled pedestrian crossing across Brighton Road.

Upgrade on Horsham Road bridge from current uncontrolled crossing to a signal-controlled pedestrian crossing.

7. Will roads have to be closed during the works?

In preparation of road-widening, works to the side of Brighton Road, next to the gyratory and access to Moto’s service station.

Widening works to both ends of the gyratory.

Creation of a four-arm roundabout serving the Moto service station and the new residential development.

9. Can work be carried out overnight?

The M23/A23 at Junction 11 will be closed overnight occasionally.

Diversions up and down the slip roads will be put in place and advance warning will be given to minimise disruption.

10. What disruption can road users expect?

Due to the speed restrictions and traffic management, journey times will increase during the works.

It is hoped some drivers will be able to find alternative routes.

11. Will there be any diversions?

Diversions up and down the slip roads will be put in place ‘infrequently’ overnight to allow work to the bridge pillars to be carried out at a time to minimise disruption.

12. Will there be speed restrictions?

Speed restrictions will be put in place leading up to and through J11 which will slow traffic to make it safer for workers.
