Refurbishment works to Alexandra Dock flyover between Moody Lane / Westgate roundabout and Lockhill roundabout will be starting next month, from Monday 13 April.
Further information is available below about the detail of the works.
Detailed programme
From 13 April, CR Reynolds will be initially undertaking temporary works to set up the site and build new crossover sections so that traffic will be able to cross from one side of the bridge to the other at various points.
The crossovers will be constructed during the day-time, and involve lane closures during that first week to provide a safety area for site staff to work in.
During this week, eastbound traffic will be filtered in advance of the Shell roundabout (on the Gilbey Bridge section), and westbound traffic will be filtered from before Cleethorpe Road Bridge. Traffic travelling along Westgate and over Alexandra Dock bridge will be in a single lane in each direction. After the first week, and completion of the temporary crossovers, the roadworks will be reduced to the minimum required to undertake repair works to the bridge.
Full traffic management for the refurbishment scheme, to install contraflows, will be put in place overnight on 20-21 April from 8pm. This work will require a full closure of Westgate, including Alexandra Dock Bridge, overnight, both ways, and traffic will be diverted through Grimsby. Traffic management will also be installed on Victoria Street at the northern end, next to Lockhill roundabout to help filter traffic into the new contraflow.
Once the bridge closure is removed (in the early hours of 21 April), a short contraflow will come into force (on a section of Alexandra Dock Bridge) and westbound traffic will be filtered to the opposite carriageway for approximately 200m. It will then revert to the westbound carriageway and have two lanes of contraflow traffic for the majority of the stretch between the roundabouts.
The main refurbishment works will begin on 21 April on the westbound carriageway and will take approximately 10 weeks. During the 10 weeks, the contraflow arrangements will be altered to allow for full resurfacing works to the whole section to be completed. Dates for this will be released as the work progresses.
Once the westbound works are complete, a full overnight closure will then be required to reverse the traffic management and switch the eastbound traffic management to the opposite carriageway.
Works will then take place on the eastbound carriageway, and again, take approximately 10 weeks, following the same pattern as the westbound works.
There will be free local recovery provided within the contraflow sections for any cars that breakdown or if there are accidents during the works.
The main diversion route will be through the centre of Grimsby to avoid the works. Abnormal load carriers and local businesses have been advised of the works.
