    Overnight closures on A63 Castle Street scheme

    Essential works on A63 Castle Street and the new junction at Mytongate as part of the major project to improve journeys in Hull are continuing.

    A new split-level junction, a critical part of the upgrade, is being created by lowering the level of the A63 to create an underpass, with Ferensway and Commercial Road crossing the A63.

    To allow the next stages of the work to be carried out safely, there will be overnight closures of the A63 Castle Street on the following dates:

    Full overnight closures (eastbound and westbound)

    8pm until 6am

    Monday 12 August

    Tuesday 13 August

    Wednesday 14 August

    Thursday 15 August

    Friday 16 August

    Full overnight eastbound closure

    8pm until 6am

    Friday 13 September

    The closure will be in place between Daltry Street and Roger Millward Way. We are doing all we can to minimise disruption.

    People can still access the city centre for parking, and all venues, events and the retail areas, with diversions in place; however, drivers are advised to plan ahead and allow extra time for their journeys.

    During the overnight closures, some of our work may be noisy in some areas and we will try to complete any noisier work as early as we can. We apologise for any disruption during this complex phase of the scheme.

    Diversion routes

    A fully signed diversion will be in place via the A15, A164, A1079 and A1033 for eastbound traffic, and vice versa for westbound.

    New junction for A63 Castle Street takes shape

    At Castle Street, we're creating a new split-level junction, a critical part of our upgrade

    We're doing this by lowering the level of the A63 to create an underpass, with Ferensway and Commercial Road crossing the A63.

    We're making progress excavating the of the underpass, working overnight.

    We will need to make road closures while we work at A63 Castle Street and the new Mytongate junction. Closures can change at short notice. Make sure you check the latest information on our daily closures page.

    We apologise for any inconvenience and appreciate everyone’s patience while we work.

Project information

Overview

We’re planning to create a new junction by lowering the level of the A63 at the Mytongate junction. Ferensway and Commercial Road would cross the A63 creating a split-level junction. Between Princes Dock Street and Market Place we propose to widen the eastbound carriageway to three lanes. We also plan to construct a new bridge over the A63 at Porter Street. These improvements will improve access to the port, congestion, safety and connections between the city centre and the tourist and recreational facilities.

Archaeology

As part of our improvement work, our team of archaeologists discovered a wealth of information about the lives of Hull society at a time when the population was rapidly expanding in the 18th and 19th century.

Mytongate junction restricts the flow of traffic along the A63, causing congestion. It is used by approximately 47,000 vehicles each day and delays at peak times can cause problems for people and businesses. The A63 acts as a barrier between the city centre to the north and the retail and dock areas to the south. We need to create better connections between the two areas.

To create the new underpass and junction upgrade at Mytongate we need to change the way the roundabout is used.

This will allow us to move traffic on the A63 so we can work more during the day and minimise disruption for residents and will be in place until the underpass has been built.

Below you will find a series of maps, in alphabetical order, which will show you how you can access businesses around the junction.

Drivers also can't turn right from all directions (from A63 eastbound and westbound, Ferensway and Commercial Road).

Drivers travelling along Ferensway and Commercial Road also can't go straight on.

No right turns diagram

The diversions at the junction are expected to add up to ten minutes to journeys so please allow extra time for your journey. We've kept them to our network as much as possible to avoid increasing traffic on the local roads.

Bonus Arena, Princes Quay shopping centre

Access to Myton Street from the A63 has been closed. To access Bonus Arena, Princes Quay shopping centre and other businesses in this area please use Ferensway, Osborne Street and Waterhouse Lane.

The map below also shows how to access the venues if travelling westbound and if you miss the turning eastbound.

Please remember that Myton Street is one way around the arena.

Mytongate footpath diversion routes

We’ve recently closed several pedestrian crossings across the A63 to allow us to build an underpass. We advise you to use these routes and stay safe rather than taking a chance on crossing elsewhere. You can also provide feedback on our feedback form.

Cyclists are currently prohibited from using the A63 while work is ongoing along the route. We encourage cyclists to use the current cycle/footpath from Daltry Street flyover and exit at Porter Street to access one of the existing routes in place on Hull City Council’s network. Check routes on the Travel Hull cycle map If travelling from the opposite side, check the map for the closest routes.
