Major Scheme

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

Cost:  £129 million to £192 million


Temporary Land

We are now seeking views from affected landowners and stakeholders on proposed areas of land required temporarily to construct the scheme and the proposed route for drainage. Various plots of land in the vicinity of the scheme are being considered for site compounds, material storage or material treatment areas. The sites may be required for the full duration of the construction of the scheme, which is currently expected to be approximately four years.

Bridge consultation

A consultation on the design options for the proposed new footbridge over the A63 at Princes Quay took place between 20 January 2014 and 18 February 2014, the consultation documents are still available to view on the A63 Castle Street consultation page. We are now considering your responses as we develop the proposals further. Thank you to everyone who provided comments.

Pre-application consultation

We have previously conducted a pre-application consultation between Friday 28 June 2013 and Thursday 15 August 2013. The consultation documents are still available to view on the previous A63 Castle Street public consultation page.

We are now carefully considering your responses as we develop our proposals further. Thank you to everyone who provided comments.

What is happening?

We propose to improve a 0.9 miles (1.5km) stretch of the A63 at Castle Street by lowering the level of the road into a cutting by approximately 7.6 yards (7 metres) at Mytongate Junction. Ferensway and Commercial Road would pass over, being raised by approximately 1.09 yards (1 metre), creating a split level junction.

When and where is this happening?

This section of the A63 Castle Street is a dual carriageway which runs in an east-west direction to the south of Hull city centre, between Porter Street and Myton Bridge for a distance of approximately 0.9 miles (1.5km). The route is one of the busiest sections of road in the whole of East Yorkshire and is an important link between the M62, Humber Bridge and Port of Hull.

The A63 improvement scheme is one of six selected by the Government to have its design and development work funded now, for potential construction after the 2014/15 financial year. Start of work on the full scheme is subject to the satisfactory completion of statutory processes and the availability of funding in the next spending review.

Why is this happening and what will it cost?

On 8 May 2012, Roads Minister Mike Penning, announced that funding would be provided in this Spending Review period to develop the A63 Castle Street Improvement Scheme, "to ensure a 'pipeline' of future Highways Agency major infrastructure improvements will be maintained, contributing to future economic growth, and supporting Government's National Infrastructure Plan." By developing the scheme now, it will be in a good position to be considered for delivery in the early years of the next Spending Review period (post 2015). The estimated cost of this scheme is in the range of £129 million and £192 million.

In the meantime the scheme will be designed to a higher level of detail and consultations will continue with key stakeholders and members of the public to discuss scheme details and to ensure that the scheme benefits as many people as possible.

It is important to note that by advancing this scheme through its development phase, this does not guarantee its construction; this decision will be taken at the next spending review. For more information visit our Future Spending Review page.

How will the scheme be carried out?

We would widen the eastbound carriageway to three lanes between Princes Dock Street and Market Place, with the nearside lane being marked for local weaving traffic. The westbound carriageway would have two lanes, as at present.Provide pedestrian footbridges at Porter Street, in front of Princes Quay shopping centre and at Market Place, to allow pedestrians to cross above Castle Street. We propose to close accesses from Castle Street on safety grounds, alternative accesses would be provided.

What are the benefits?

The objectives of this scheme are to improve access to the Port of Hull, relieve congestion and improve safety. In addition, the project seeks to reduce the impact of the barrier caused by Castle Street between the city centre to the north and developments, tourist and recreational facilities to the south.

How do I find out more information ?

More information will be posted on this project page as it becomes available. You can subscribe to be alerted when updates are made.
