All northbound lanes on Interstate 5 from Carlsbad Village Drive to Vista Way will be closed overnight Monday, according to Caltrans San Diego.
The closure will take place from 11:30 p.m. Monday to 4:30 a.m. Tuesday, when crews will continue placing an overhead sign structure in the city of Carlsbad, the agency said.
Caltrans shared a graphic showing the detour route in green. According to the map, travelers will exit at Carlsbad Village Drive, go up El Camino Real and return to I-5 either from Vista Way or State Route 78.
