OCTA, in cooperation with Caltrans, is improving 6.5 miles of I-5 between SR-73 and El Toro through Mission Viejo, Laguna Niguel, Laguna Hills, and Lake Forest.
The $580 million I-5 South County Improvements Project is being built in three segments and includes roadway, structural and operational improvements that will benefit mobility throughout the area.
As part of the project, crews are conducting pile driving for a retaining wall at the northbound Crown Valley Parkway on-ramp.
Pile driving is a common method of constructing structure foundations. To support the structure, steel beams, or "piles," are driven into the soil until reaching a hard layer of earth beneath the structure foundation. Crews then install rebar, pour footings and form the wall.
Once complete, the wall will be 1,328 feet long, ranging in height from 16 to 26 feet and featuring a slate stone finish.
