Preparation works for the 1.2km Howden Relief Road which will link the A614 Thorpe Road with Station Road will get underway next month with local Hull firm PBS Construction understood to be carrying out the work.
This will pave the way for full construction work to start in January 2025, with construction taking around 29 months.
The scheme was approved as part of proposals to build 1,900 homes, a school, a pub and an additional factory for Howdens Joinery.
Funding for the scheme will jointly come from contributions by local housing developers and the council.
Adam Holmes, director of infrastructure and facilities at East Riding council, said: “We need to undertake this initial work to ready the site for when the main construction begins next year.
“When it’s complete, we hope the relief road will be a huge benefit to Howden by taking some larger traffic away from the congested town centre, and will also be a help to drivers by providing a new, quicker route.”
