FOR IMMEDIATE RELEASE
AUBURN – Caltrans and its contractors have made significant progress on improving traffic flow and signal coordination on the State Route 49 (SR-49) roadway rehabilitation and complete streets project in Auburn.
Caltrans had previously identified electrical malfunctions in 12 of the 17 electrical cabinets that control coordinated traffic signal timing on SR-49 between the Interstate 80
(I-80) separation and Dry Creek Road. Over the last several weeks Caltrans, its electrical subcontractor and the electrical cabinet manufacturer have been actively working to diagnose and correct the issues to restore signal coordination to improve traffic flow.
As of Friday, all traffic signal vehicle detection camera systems have been activated, which has improved traffic flow on the highway. The Caltrans Signal Operations team is currently in the process of activating the signal interconnection system between I-80 and Dry Creek Road, and fine-tuning signal timing between the mainline and secondary streets.
Additional testing by Caltrans and its Materials Engineering and Testing Services unit has identified an electrical malfunction with the traffic signal cabinet at the Bell Road intersection. The cabinet will be replaced, but motorists may still experience intermittent timing detection issues in the meantime.
Caltrans asks for continued patience during final signal timing coordination work in Auburn. Motorists are also advised to be alert for temporary flashing red signals while diagnostic testing and signal fine-tuning is completed. The public is also reminded to treat flashing red signals as all-way stops.
Project updates will be posted on the State Route 49 Comprehensive Multimodal Corridor Plan page.. The public may also contact Public Information Officer Raquel Borrayo at raquel.borrayo@dot.ca.gov and request to receive project updates via email.
District 3 is responsible for maintaining and operating 4,385 lane miles in 11 Sacramento Valley and Northern Sierra counties.
