Adelaide Road between the Quinsborough Road and Florence Road in Bray will be closed to traffic for four days from tomorrow.
The County Council says the closure is to facilitate the connection of services to the public water main and sewer system.
Pedestrian traffic will be facilitated as much as possible.
The closure will run until Friday.
Diversion for traffic in both directions is along the Quinsborough Road, Wyndham Park and Florence Road.
