The Highways Agency is advising road users that the A23 northbound exit and entry slip roads will be closed overnight from this Friday (17 January) for three nights.
During the closures safety barriers will be installed on the slip roads ahead of the new road layout planned for the beginning of February.
The northbound exit and entry slip roads will be closed overnight between 8pm and 6am on Friday, Saturday and Sunday January 17, 18 and 19.
The work is part of the on-going £79m upgrade currently underway along 3.8kms of the A23 between Handcross and Warninglid.
During the latest sliproad closures, the Highways Agency says road users will be directed to follow a fully signed diversion via Pease Pottage for the exit slip road and via the B2115 and B2110 for the entry slip road.
