A63 Castle Street
We’re improving a section of the A63 Castle Street in Hull.
Information on how to get to local businesses can be found in the 'Project information' section below.

ECHO is a one-way feedback tool, so if you’d like a response to your feedback you can email the project team at: A63CastleStreet.Hull@nationalhighways.co.uk
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.
You can view what the improvements will look like by watching our fly through video.
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.
We’ve launched a dedicated webpage for the archaeology work that we’re carrying out as part of the A63 Castle Street scheme. There you will be able to keep up to date with all the latest finds and insights and how we’re piecing together Hull’s history.
You can also sign up for notifications so that every time the webpage is updated with new information you’ll receive an email.
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.
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.
Holiday Inn, Kingston Retail Park, Nuffield Health, Whittington and Cat pub
To access the businesses in the Commercial Road, Kingston Street, English Street and Lister Road areas please leave the A63 at Daltry flyover if travelling eastbound following the black solid square.
If travelling from the north or west please follow the solid circle on the yellow and black signs.
Overnight closures
When the A63 is closed overnight between Daltry Street and Roger Milward Way roundabout and you wish to continue along the A63 please follow the below diversion route.

We’ve recently closed several pedestrian crossings across the A63 to allow us to build an underpass. People are advised to use these routes and stay safe rather than taking a chance on crossing elsewhere. You can also provide feedback on the route by visiting our feedback form.
Cyclists currently are prohibited from using the A63 while work is ongoing along the route. However we’d 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, see map here for reference: https://www.travelhull.co.uk/bike/cycle-map If travelling from the opposite side please refer to the map on the closest routes.
Documents
Our Castle Street principal contractor Balfour Beatty was delighted to support the Humber STEM event at Sewell Group Craven Park on 1 July.
The event was attended by 600 primary school children and 30 businesses.
More than 150 pupils visited Balfour's activity which was to build the tallest and strongest structure.
Castle Street archaeologists from Oxford Archaeology Limited were also in attendance with a mini archaeology dig which went down a storm.
