Major Refurbishment works are due to start today at the Alexandra Dock Flyover in Grimsby.

The work is expected to take over twenty weeks to complete.

There'll be lane closures this week - with diversions and full closures later this month overnight

Temporary works are being initially done 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.

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.

The main diversion route will be through the centre of Grimsby to avoid the works.
