The Plumas County Board of Supervisors raised the speed limit on Lee Road in Quincy to 35 miles per hour for its entire two-mile length.
Currently, the speed limit is 25 miles per hour from State Route 70 past Pioneer School to the Sierra Pacific sawmill. It increases to 35 miles per hour from there to Quincy Junction Road.
Rob Thorman, director of the county public works department, based the change on a recent engineering and traffic study. California Vehicle Code requires updating speed zones with such studies every five to seven years.
The study showed the average critical speed on the 0.61-mile east section of Lee Road at 34.5 miles per hour. On the 1.46-mile west section, the average critical speed reached 39.5 miles per hour, with a median speed of 34.
Thorman explained that faster driving leads to higher speed limits. Raising the limit allows law enforcement to use radar to enforce speeds on Lee Road, starting August 21.
The supervisors also limited truck weight to 14,000 pounds on Redberg Avenue, Pioneer Road, and Rogers Avenue. These narrow residential streets pose risks for large commercial vehicles.
The Public Works Department will install signs to redirect commercial traffic away from these neighborhoods. The weight restrictions took effect after the supervisors approved the ordinance on July 21.
