Caltrans workers will begin fixing the Hartnell Avenue over crossing next week.
The bridge was damaged last month when a big rig carrying a car crusher drug its load across the bottom of the overpass.
Work will begin Monday night and will continue from 8 p.m. to 6 a.m.. Monday through Friday.
Traffic on I-5 will be reduced to one lane in the southbound direction during those hours. East bound lanes on Hartnell will be opened to two-way traffic.
The estimated $1 million project will include removing damaged concrete and repairing structural steel. The process is expected to take between 30-45 days.
