FOR IMMEDIATE RELEASE

SACRAMENTO COUNTY — In a continued effort to improve traffic flow along State Highway 99, Caltrans will install 10 Variable Speed Advisory (VSA) signs in the northbound direction from Elk Grove Boulevard to the U.S. Highway 50 interchange.

Beginning November 1 motorists will see VSA signs displaying advisory speeds that will change based on traffic conditions along the corridor. These signs will be operational during the weekday morning commute times as part of a pilot project with a study duration of six months.

Caltrans is collecting data to see if the program helps reduce stop-and-go traffic during high congestion travel times by using these signs along with the ramp meters that are already in place. 

The goal is to reduce speed fluctuations to a manageable flow, improve safety by lowering the number of rear-end collisions and reduce vehicle emissions.

Caltrans District 3 maintains more than 4,385 lanes miles of state highway in 11 Sacramento Valley and Northern Sierra counties. The department issues updates about road conditions on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3.
