A63 Castle Street Scheme, Hull

This £355 million improvement scheme will relieve congestion for 47,000 road users and improve access to the Port of Hull.

Beginning work on site in 2020, our works include lowering the level of the A63 at the Mytongate junction to create a split-level junction, widening the eastbound carriageway to three lanes and installing a new footbridge to create a safer route for pedestrians and cyclists crossing the A63.

Uncovering Hull’s history

To make way for the new slip road off the Mytongate Roundabout required the largest scientific excavation of a post-medieval burial ground in Northern England, with a team of 90 archaeologists sensitively excavating an estimated 10,000 bodies which were subsequently re-buried within the boundaries of the burial ground.

Due to the size, scale and significance of the archaeological works, they were featured on the BBC’s Digging for Britain series. The show's host, Professor Alice Roberts, visited the burial ground to meet the team and go behind the scenes to see our on-site laboratories and find out more about the wealth of information we had uncovered about the history of the local area.

Reducing our carbon footprint

Working towards our ambition to go beyond net zero carbon by 2040, we successfully used electric mini diggers on this project. Powered by a Prolectric ProPower Solar Generator, the electric diggers reduced our carbon output by 25 tonnes and resulted in better air quality in the tent used during the archaeological works.

A local first legacy

To create a meaningful, lasting legacy for the local community, we have been helping schools, colleges, the local university and local charities by:

  • Delivering activities for nearly 4,000 local students to encourage them to take up a career in Science, Technology, Engineering or Mathematics (STEM)
  • Participating in a Women in Manufacturing and Engineering pilot to encourage more women into STEM careers
  • Recruiting apprentices from the local area
  • Raising money for charities including Macmillan Cancer Support, Anthony Nolan and blood cancer charity DKMS
  • Donating items to a local foodbank and women’s refuge as well as materials and staff time for an episode of the BBC’s DIY SOS.
