the end of the year.
The Talbert Avenue and Magnolia Street bridges, along with the first half of the Bolsa Avenue bridge, are expected to open in the first half of 2021. Later in the year, the Heil Avenue pedestrian overcrossing, along with the Edwards Street, Bolsa Chica Road and Goldenwest Street bridges are scheduled to open.

The I-405 Improvement Project, now more than halfway complete, will add one regular lane in each direction between Euclid Street and I-605, and a second lane in each direction in the center of the freeway from SR-73 to I-605 that will combine with the existing carpool lanes to form the 405 Express Lanes.
This 16-mile segment of I-405 is one of the most heavily traveled stretches of highway in the nation, and drivers routinely face severe congestion in both the regular lanes and carpool lanes. The project is critical to accommodate expected employment, population and housing growth throughout the region.
The speed limit on I-405 has been reduced to 55 mph between SR-73 and I-605 for the safety of drivers and construction crews for the duration of the project, which is expected to be completed in 2023. Drivers are advised to slow down and proceed with caution whenever signs of highway work are present.
