Emergency works are being carried out by North East Lincolnshire Council and its regeneration partner, ENGIE, to fix a sink hole discovered during overnight works on Bargate, between the Abbey Road and Westward Ho junctions.
The northbound carriageway (travelling into Grimsby town centre) will remain fully closed while contractors excavate the sink hole and reconstruct the sublayers of the carriageway, following the collapse.
A full northbound closure is required due to the depth of the sink hole and the extent of the work required to reconstruct the carriageway.
Works are estimated to take seven days to complete, but motorists are being warned that the timescales for repair are unable to be confirmed until the sinkhole has been fully excavated. Engineers and the contractor will be working as quickly and safely as possible to fix the carriageway and ensure it can be reopened as quickly as possible.
The southbound carriageway will remain open during the daytime and access to Westlands Avenue will be maintained.
Stagecoach have been informed of the closure and will be continuing to use the diversion route via Westward Ho, Littlefield Lane and Dudley Street when travelling into the town centre.
North East Lincolnshire Council and its regeneration partner, ENGIE, would like to apologise for the inconvenience. Sink holes occur naturally all over the world and are a usually the result of geological processes.
