Did you know? To update some of Orange County’s most vital infrastructure, the project contractor used: -172,000 cubic yards of Redi-Mix concrete -360,000 tons of asphalt -38,000,000 pounds of bridge rebar #InfraStructure #FasterFuture #405Improvement

The water is held in the basins & filtered before soaking back into the ground or is released into the storm drain system. The project team continues to monitor the basins to ensure they are working correctly.

You may have noticed that water is ponding in some ramp areas with the recent rain events. As part of the project, crews installed detention & infiltration basins, per Caltrans’s requirements, in these locations to address storm water capacity & water quality.

Check out Newland Street bridge’s NEW look! This was the last bridge on the project to be demolished for reconstruction. Newland’s bridge improvements included construction of a new northbound sidewalk, bike lanes in both directions, and two additional vehicle lanes.

McFadden Street bridge was the first on the project to receive demolition construction activities. Upon its reopening in 2020, the bridge unveiled 2 additional vehicle lanes, new bike lanes on both sides and a new eastbound sidewalk! #McFadden405 #FasterFuture #405Improvement

@SnapCasterDANK The first of these projects is anticipated to begin in early 2024. For the duration of the project, the project contractor will continue to monitor and investigate the roadways for potholes and add to their maintenance queue as needed. Thank you.

@405improvement What about the pavement in the lanes? It is so bad going north in some spots. Forget the plants already and reduce the wear on our cars.

@SnapCasterDANK Hi, Landscaping throughout the project area is a part the I-405 Improvement Project. The majority of all project paving has been completed. After the project is completed, Caltrans has several project plans including pavement rehabilitation on the I-405.

As we move towards total project completion/closeout, crews continue landscaping throughout the corridor. These shots showcase fresh landscaping in the City of Seal Beach. #Landscaping #Construction #OrangeCounty #OC #405Improvement #CaltransOC
