Better connections up ahead as new A63 Castle Street underpass develops

Via National Highways

Work on a new underpass for the A63 Castle Street in Hull is moving forward, creating better connections for drivers in the city centre.

Significant progress has already been made and the next stage will see the installation of new wall panels in the 400m underpass, where east-west traffic will travel below north-south traffic at the current Hull Mytongate junction. New lighting will also be installed at Porter Street.

The work is part of National Highways’ £355m upgrade to A63 Castle Street. The scheme will improve access to the port, reduce congestion and enhance safety as well as connections between the city centre and tourist and recreational facilities. Expected to be complete in 2025, it will support Hull’s economic growth, improving journey times to and from the city centre, and help the nearby port to thrive.

Frances Oliver, Project Manager at National Highways, said: “The construction of the underpass is one of the most important and complex parts of the A63 Castle Street scheme and we’re delighted to say that this work remains on track.”

National Highways has carried out deep excavation work to create the new 400m section of underpass. As well as forming the underpass walls, there has been extensive intricate piling work – the process of driving foundations through the ground to provide greater stability and strength to the structure.

In total, 200 wall panels are being installed in the underpass.

To ensure the next phase of work can be carried out safely, overnight closures will be in place on the A63 between Roger Millward Way and Daltry Street.

The westbound carriageway will be closed each night, from 8pm until 6am, on these dates:

  • Tuesday 19 April – Friday 22 April
  • Monday 25 April – Friday 29 April
  • Tuesday 3 May and Wednesday 4 May

The eastbound carriageway will also be closed from 8pm until 6am on Tuesday 19 April.

Ms Oliver said: “The overnight closures mean we can safely carry out work on the underpass walls close to the road.

“Once this underpass is complete, it will create better journey times and safer connections between the city centre and the retail and docks area.”

Deep dry mixing work is also taking place overnight, every Monday to Friday night, between Porter Street and Murdoch’s Connection. This work is expected to be in progress until late July.

Ms Oliver said: “We’re not anticipating this work to create significant noise disruption in the area. However, we will continue to monitor sound levels and take action where necessary.

“Once again, I would like to thank everybody for their patience while we carry out this work.”
