About A63 Castle Street

We’re creating a new junction by lowering the level of the A63 at the Mytongate junction in Hull.

The local roads, Ferensway and Commercial Road, will cross the A63 creating a split-level junction.

The junction is used by around 47,000 vehicles and restricts the flow of traffic, causing congestion for people and businesses travelling at peak times.

To help we’ll widen the eastbound carriageway to three lanes between Princes Dock Street and Market Place and a build a new bridge over the A63 at Porter Street as part of the £355m scheme.

These improvements will improve access to the port, congestion, safety and connections between the city centre and the tourist and recreational facilities.

It also includes the largest scientific excavation of a post-medieval burial ground in northern England with the archaeology work taking place at Trinity Burial Ground.

The scheme started in March 2020 and is due to complete in spring 2025.


Visitors will be escorted around the site and will be able to see the excavation work that is taking place to create the new underpass.

There will be the opportunity to talk to some of the staff about the complexities of the scheme and what it’s like working on such a major scheme in a city centre close to residents and businesses.

Information on Open Doors 2022 will be released shortly
