A63 Castle Street Improvement

Scheme outline

Provision of a new grade separated junction on the A63 in Hull, with the aim not just of improving traffic flow, but also improving access to the port of Hull, and reconnecting Hull city centre with the river by reducing the barrier effect of the current A63.

This will be achieved by lowering the level of Castle Street by 7 metres into a cutting, as part of the grade separation of the Mytongate junction. Ferensway and Commercial Street would be raised by a metre to pass over the junction.

The scheme also includes widening of the eastbound A63 carriageway to provide three lanes between Princes Dock Street and Market Lane.

Some of the space needed to construct one of the slip roads currently forms part of the Trinity Burial Ground. It is estimated that up to 16,000 burials may be situated within this area - any remains would need to be exhumed and re-buried before any construction work could begin. The Highways Agency website states that they plan to submit the Development Consent Order in Spring 2015.
