Northbound Highway 99 will be shut down in Galt tonight and Wednesday for construction work.
The northbound lanes will be closed at the A and C streets overpasses from 11 p.m. to 4 a.m. on both days. A detour will be in place and motorists are advised to plan for delay in travel.
The detour is needed to perform bridge work, part of a nearly $40 million interchange replacement project at C Street, scheduled for completion late this year.
Construction closures began Monday night.
