The A160 will be closed overnight on Saturday (6 June) to carry out work to lay a new power cable as part of a major scheme to provide better access to the port and the surrounding area.
The westbound carriageway from Rosper Road to Manby roundabout will be closed from 8pm Saturday 6 June to 10am Sunday 7 June.
Manby roundabout will be partially closed to prevent eastbound traffic approaching the roundabout taking the A1173 exit to Immingham. The roundabout will be reduced to one lane running during the work with the outer lane remaining open.
Westbound traffic will be diverted via Rosper road and Eastfield road. Drivers on the A180 traffic heading to Immingham will be diverted via Stallingborough junction and the A1173.
All closures have been carefully scheduled to minimise disruption to drivers and will be put in place when traffic flows are at their lowest.
