Selby River Ouse Swing bridge on the A63 will undergo maintenance work and its annual service during half term.
The A63 over the bridge will be closed during the works which will take place from 6pm on October 23 to 6am on November 2.
The project involves replacing the steel transition plates between the approach road and the steel bridge deck. The annual service will also be carried out.
“The transition plates had been adjusted during yearly services to minimise noise and vibration as traffic passes over,” said local member Councillor Karl Arthur. “However, due to age and general wear it is no longer possible to adjust them further and movement of the plates has become excessive. As such it is essential that we carry out these works now.”
Local member Councillor Stephanie Duckett added: “The closure is required as the bridge needs to be open so scaffolding can be erected to provide a platform to work on. The work has been timed for the school holidays to minimise disruption but we apologise for the inevitable delays.”
Advance warning signs will be in place and there will be a signed diversion during the road closure period.
Operatives working on site will be observing all Government guidelines on safe social distancing.
