AUBURN – Caltrans is alerting State Route 49 motorists to expect travel delays Thursday evening and overnight for traffic signal work at the Bell Road intersection in Auburn.

During the recent activation of new traffic signal vehicle detection cameras throughout the corridor, a malfunctioning electrical cabinet was diagnosed at the Bell Road intersection. Electrical crews will be replacing the cabinet with a new one, requiring overnight signal work and testing.

Motorists should expect travel delays and lane reductions between 6 p.m. Thursday, Nov. 18 and 5 a.m. Friday, Nov. 19 at the intersection.

During electrical cabinet replacement, the Bell Road intersection signals will remain in flashing red mode. Caltrans will have traffic control flaggers on site for safety, however, motorists are reminded to treat flashing red signals as all-way stops. Motorists are also advised to use alternate routes to avoid travel delays during signal work.

The Caltrans Signal Operations team has continued activation of the signal interconnection system this week between I-80 and Dry Creek Road, along with fine-tuning signal timing between the mainline and secondary streets. Caltrans asks for continued patience during final signal timing coordination work in Auburn.

Project updates will be posted online at The public may also contact Public Information Officer Raquel Borrayo at and request to receive project updates via email.
