Auburn – Caltrans is alerting motorists of delays in the Borland Avenue closure along State Route 49 (SR-49) in Auburn as crews continue work on the $9.9 million American Canyon Roundabout Project.

The Borland Avenue intersection with SR-49 will now remain closed until Friday, December 22. Crews have experienced delays over the last month due to weather and utility work.

Caltrans would like to remind motorists that local businesses along Borland Avenue remain open and can be accessed with a detour. Signs are in place to lead motorists northbound on SR-49 and exit left at Lincoln Way. From there, motorists will take Cherry Avenue to Brook Road and turn back onto Borland Avenue.

The project is the second of three recent Auburn-area projects to improve safety on the SR-49 corridor in Placer County. The project will realign two reversing curves to improve sight distance and safety by reducing the sharpness of each curve. Additionally, the existing traffic signal at the Lincoln Way/Borland Avenue intersection will be replaced with a roundabout to improve safety and traffic flow.
