Major Scheme

Part of our programme of improvements (value >10m)

Cost:  £135.1 - £201.6 Million


Ground Penetrating Radar survey

Highways England will be carrying out a Ground Penetrating Radar (GPR) survey as from 16 August 2016 on and around the A63 Castle Street. The survey is being carried out to locate buried objects, such as pipes and cables, which may need to be diverted during the construction of A63 Castle Street Improvement scheme. The survey is being carried out at this time to help inform the design of the improvements and is expected to last approximately 12 weeks.

The GPR survey does not require any digging and is undertaken using both vehicle mounted and trolley mounted equipment and there will be some night time working to minimise disruption to the public. The survey will also need to be carried out on some local roads during the 12 week period. Those affected will be notified, by letter, no later than 2 weeks before the survey is due to commence on any particular street.

Princes Quay bridge

We remain committed to constructing a footbridge at Princes Quay in Hull and we are working hard on the plans. We have jointly taken the decision with Hull City Council to reschedule construction work to avoid disruption to the City of Culture celebrations in 2017.

This decision to reschedule the work was taken after results from the recent ground investigation work revealed it would not be possible to open the bridge until autumn 2017. This is due to a number of technical issues relating to the foundations of the bridge. More work is needed on the existing marina wall before engineers can start installing foundations for the bridge.

The archaeological and ground investigation work will continue to take place on site over the next few weeks and will inform construction work which will now start at a later date.

The bridge will be built after 2017 and a final decision will be made on the timing of this once traffic and environmental assessments have been completed this summer.

Archaeology work in Trinity Burial Ground

We have successfully completed archaeological investigations at Trinity Burial Ground. This work has been extremely important in helping us to plan for the construction of the Castle Street improvement scheme. The investigation has also provided a significant amount of historical information about the burial ground and Hull itself.

If you are interested in finding out more, download our fact sheet.

The burial ground will fully reopened by the end of March 2016.

Archaeology work Marina and North side of Castle Street

We’re investigating parts of Hull’s medieval defences to help understand more about the history of Hull and the people who lived here. Around 700 years ago brick walls and ditches were built to protect the town from invaders, but these have since crumbled away or been removed. Our work aims to discover where the old walls were built. It will also mean that archaeologists can find out more about what they were made of and how they were constructed. The work near the Marina will be completed in mid-March.

What is happening?

We propose to improve a section of the A63 Castle Street in Hull. We plan to create a new junction by lowering the level of the A63 at 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 3 lanes.

We also plan to construct 2 new bridges over the A63:

  • at Porter Street
  • a bridge in front of Princes Quay Shopping Centre

When and where is this happening?

This section of the A63 is approximately one mile long and stretches between Porter Street and Myton bridge. The A63 runs through the southern part of Hull in an east-west direction. It’s an important link between the M62, Humber bridge and the Port of Hull.

We are working hard to finalise the Development Consent Order and will submit it as soon as further necessary traffic and environmental assessments have been completed. We expect to be able to complete these assessments in summer 2016, which will inform our timetable for the delivery of the A63 improvements and the Princes Quay bridge.

Why is this happening and what will it cost?

Mytongate junction restricts the flow of traffic along the A63 which can slow people’s journeys. The busy road, which has approximately 54,000 vehicles travelling along it each day, can impact a large number of people and businesses. The A63 also acts as a barrier between the city centre to the north and the retail and dock areas to the south. This means we need to create better connections between the two areas.

We estimate that the improvement scheme will cost in the range of £135.1 - £201.6 Million

How will the scheme be carried out?

We will need to carry out a significant amount of construction work to build the new junction and 2 bridges.

Before starting construction it’s vital that we first carry out a number of ground investigations and archaeological surveys. These will help us to plan our construction activities in the best possible way. Once we’ve carried out the investigations and detailed planning, we will share more details on this web page about our planned work.

What are the benefits?

Completion of the scheme will provide:

  • improved access to the Port of Hull
  • congestion relief
  • improved safety
  • improved connections between the city centre to the north and developments, and tourist and recreational facilities to the south
