SR-22 Safety Improvement Project

Over $20 million in improvements will be made to the Eastbound segment of the Garden Grove Freeway (State Route 22), widening the inside of the horseshoe connector to three lanes that service Northbound Interstate 5 and Northbound State Route 57, removing a half a mile of the collector-distributor road concrete barrier, and extending the concrete barrier to provide access to the horseshoe connector.


Due to a number of factors, there is a significant number of collisions on Eastbound State Route 22 between State Route 39 and Interstate 5 when compared to similar stretches of California highways. Most notably, the high volume of traffic contributes to an increase in the difficulty and delays that drivers face on this portion of infrastructure.

The SR-22 Saftety Improvement project proposes to shorten the length of the collector-sistributor road and reconfigure Eastbound SR-22 at the Horseshoe connector. This work is the most recent in Caltrans’ efforts to improve the conditions on SR-22.

In 2007, Caltrans and OCTA finished an improvement project on the Garden Grove Freeway that widened the freeway (adding HOV, general purpose, and auxiliary lanes) massively improving traffic flow and safety. They also added the collector-distributor road between The City Drive in Orange and I-5 and State Route 57. Through this new safety project, Caltrans will further optimize that collector-distributor road in specific and SR-22 in general.

Closures and Detours

As a result of closures for work, each stage of the project will require a few detours. On the detours page, you can see the currently active closures and their recomended detour routes. Additionally, when the detour routes are active, signs marking them will be placed along the roadside for your reference.
