Safety improvements to Highway 70 in Plumas County will result in continuous one-way traffic in the Feather River Canyon causing up to five-minute delays, said Trisha Coder, a spokeswoman for the California Department of Transportation.
The project includes guardrail upgrades and installation of four earth retaining structures between Cresta Dam and the Rock Creek Bridge.
Caltrans installed a temporary traffic signal last month and expects to install a second one in July or early August, Coder said. The lights allow one-way traffic in the construction areas.
In addition to these delays, one-way traffic control may be in place near the Greenville Wye, at the intersection of Highways 70 and 89, Coder said.
The traffic signals are expected to be in place until Oct. 1.
