OCTA, in cooperation with Caltrans, is improving 4 miles of SR-55 between I-405 and I-5. The project will improve traffic flow and reduce travel time by adding one regular lane and one carpool lane in each direction. Also, the project will add merge lanes between several interchanges and stripe carpool lanes for continuous access, augmenting safety on the freeway by making merging easier. These enhancements are expected to create a better, smoother driving experience for motorists.
