Crews will close the northbound (NB) I-405 loop off-ramp to westbound (WB) Westminster Boulevard and the southbound (SB) loop off-ramp to eastbound Westminster during the day to pour concrete for the new portion of the Westminster bridge.
This work will also require WB Westminster to be reduced to one lane between Willow Lane and Springdale Street.
The closures are anticipated for 5 a.m. to 5 p.m. Wednesday, March 30.
