OCTA Crews will install pre-cast concrete girders for the Fairview Bridge over I-405, requiring full closures of 405 Freeway during early morning hours starting Saturday Aug. 29.
The girders are the main horizontal support beams, known as the superstructure, for the new bridge. They are installed across the bridge’s substructure, the abutments and center columns. Pre-cast girders are used instead of installing falsework and pouring the superstructure in place.
This work will require northbound (NB) and southbound (SB) full freeway, lane and ramp closures, as well as the closure of Fairview between McCormack Lane and South Coast Drive. Residential access will be maintained.
