HOV, or carpool, lanes opened on I-5 in both directions between State Route 134 (the Ventura Freeway) and Magnolia Boulevard on April 6-7, 2021.
The newly constructed Northbound I-5 High Occupancy Vehicle (HOV) lane from SR-134 in Los Angeles to Magnolia Boulevard in Burbank — a distance of 2.7 miles — opened to traffic on the morning of April 6, 2021.
The following morning, April 7, the new Southbound I-5 HOV lane from Magnolia Boulevard to SR-134 also opened to traffic for the first time.
This milestone adds a total of 5.4 lane miles of HOV lanes in Los Angeles, Glendale and Burbank. It is part of the broader effort to widen I-5, improve interchanges and construct carpool lanes in Los Angeles County.
Each day, more than 230,000 cars and trucks travel on I-5 in this area, on average, based on recent years figures.
This project constructed an HOV lane in each direction, where I-5 had four lanes in each direction at the outset of the project. Now, motorists have access to an HOV lane in addition to four regular mixed-use lanes in each direction.
Construction of HOV lanes required crews to widen seven bridges, involving construction of concrete decks over girders.
One of the seven bridges, the I-5 bridge over the Los Angeles River, measures more than 635 feet in length along the center line. Other bridges were widened at Sonora Avenue, Western Avenue, Allen Avenue, Alameda Avenue, Providencia Avenue and Verdugo Avenue.
Another element of the project was enhancement of the sound walls along I-5.
The design phase of the project was completed in March 2009. The contract was awarded to Security Paving Co. Inc. in December 2010. The construction phase started in February 2011.
To construct this project, crews placed about 3.3 million pounds of structural steel for the bridges, more than 100,000 tons of concrete pavement, and more than 6,500 tons of asphalt.
