Road improvement work will start next month as part of the final stages of the Cottingham and Orchard Park Flood Alleviation Scheme.
East Riding of Yorkshire Council's £20m project is designed to reduce the risk of flooding to around 4,000 homes and businesses, and is due to be completed later this year.
As part of the scheme, works were previously carried out to install new drainage underneath Westfield Road and Eppleworth Road, west of Cottingham.
As that work has been completed, resurfacing work needs to be carried out on both Westfield Road and Eppleworth Road to improve the road surface.
The work is due to begin on Monday 3 August, starting on Westfield Road opposite Hessle Golf Club and working east towards Cottingham. It is expected to take two weeks to complete,
During this time, it will be necessary to close Westfield Road and Eppleworth Road to enable the work to be carried out safely for both the public and the workforce.
A traffic diversion will be in place. Access will be maintained at all times for residents and the emergency services.
The work will be carried out by ESH Construction on behalf of the council.
Dave Waudby, head of infrastructure and facilities at East Riding of Yorkshire Council, said: "We'd like to thank residents and motorists in advance for their patience while we carry out this essential work to upgrade the road surface."
The Cottingham and Orchard Park Flood Alleviation Scheme has been designed to collect 300,000 cubic metres of flood water at times of heavy rainfall - the same amount of water it would take to fill 120 Olympic-sized swimming pools - to prevent the water from reaching homes and businesses in Cottingham and Hull.
