Extended A180 contraflow planned during Grimsby resurfacing works

An extended contraflow will operate on the A180 in Grimsby for up to two weeks as resurfacing and bridge-deck works continue between Lockhill Roundabout and Westgate Roundabout.

Traffic management on one of Grimsby’s principal routes is about to change again.

An extended contraflow is due to come into operation from Monday 21 September, allowing work to move onto the eastbound carriageway of the A180. North East Lincolnshire Council has warned that delays are likely during core commuting hours.

In brief:

• An extended A180 contraflow is due to operate from 21 September for up to two weeks.
• An overnight closure from 8pm on Sunday 20 September is required to alter the traffic-management layout.
• The wider programme includes resurfacing, bridge-deck waterproofing and replacement central-reservation barriers.

A180 contraflow to support next phase of Grimsby works

The works cover the A180 between Lockhill Roundabout and Westgate Roundabout, where the full stretch is being resurfaced one carriageway at a time.

Barriers within the central reservation are also being replaced, while waterproofing work on the eastbound bridge deck is already under way.

According to the council, the existing contraflow switches traffic onto the opposite side of the bridge. That arrangement now needs to be extended so resurfacing can take place on the eastbound carriageway towards Cleethorpes.

The change will require an overnight closure from 8pm on Sunday 20 September while the revised traffic management is installed. Drivers have been advised to use an alternative route through Grimsby town centre during that closure.

The A180 will reopen once the traffic-management changes have been completed, after which the longer contraflow is expected to remain in place for up to two weeks.

The council said delays are likely during core commuting hours, both on the affected stretch and on approaches from Cleethorpe Road, the eastbound A180 and Victoria Street North. Road users have been asked to travel outside the busiest periods or avoid the area where possible.

For highways teams, the scheme illustrates how traffic management forms an essential part of delivering work on a heavily used route. The carriageway must remain available to traffic while sufficient space is created for resurfacing and other activity to continue safely.

Overnight closures are frequently used to introduce or remove such arrangements, limiting the time a route is completely unavailable. Similar considerations apply during other short-duration possessions, including night closures used for road-marking work on the A12.

Once the eastbound resurfacing has been completed, the traffic-management layout will change again to support further phases, including the installation of new central-reservation barriers.

The overall A180 programme is due to be completed by early November 2026. North East Lincolnshire Council said further information about subsequent traffic-management changes will be released when available.

For drivers, the immediate message is straightforward: the overnight closure applies while the new layout is installed, but delays could continue throughout the extended contraflow. For the highways sector, the scheme is a practical example of how bridge-deck work, carriageway renewal and barrier replacement must be sequenced while keeping a strategic urban route operating.
