Multiple lanes of highways 99 and 58 are set to take place over the next two weeks.
According to officials with the Thomas Roads Improvement Program, the two outside northbound and southbound lanes of Highway 99, between Ming Avenue and Wilson Road; the Ming southbound on-ramp; and the northbound off-ramp to Ming will be closed Sunday through Thursday nights through Sept. 28.
The closures are due to excavation activities.
There will also be closures of the two outside lanes on eastbound 58 between Chester and Union Avenues. The closures are due to wall construction.
The closures will run from 9 p.m. to 5 a.m. each night and morning.
