Carson Street will be closed from Cavitt Avenue to South College Avenue in Bryan on Wednesday through the end of the week.
The closure will begin at 7 a.m. Wednesday, and work is expected to continue through 6 p.m. Friday.
The closure is needed so the city's contractor can install an 8-inch water line on Echols Street and relocate the existing 18-inch water line running down Carson Street, city officials said.
City officials said drivers should avoid the area if possible. Drivers traveling down Carson Street should follow a detour route that will be marked with signs directing them to use Duncan Street, one block north.
