OCTA to Provide Update on the SR-55 Improvement Project

OCTA will provide a virtual presentation on Thursday, May 18, from noon to 1 p.m. on the SR-55 (I-405 to I-5) Improvement Project. This update on progress made since construction began in summer 2022 will also look ahead at activities planned for the remainder of the year. A Q&A session will follow the presentation. The meeting will be recorded and available on the Project webpage on Friday, May 19.

The SR-55 (I-405 to I-5) Improvement Project will add one regular lane and one carpool lane in each direction as well as merge lanes between interchanges. In addition, carpool lanes will be striped for continuous access, making it easier for motorists to enter and exit the lanes. SR-55 is a major north/south route connecting Orange County to Riverside and San Bernardino counties, and for accessing key business centers, John Wayne Airport and the beach cities. The $475.1 million Project is funded by OC Go (also known as Measure M), as well as state and federal funds.
