REDDING, Calif. - Caltrans announced phase two of the Dunsmuir Grade Project, which will stretch from just south of the Truck Scales to the Sacramento River Bridge on Interstate 5 in Siskiyou County.

The project's total cost is $57 million. Shea Construction, the prime contractor, completed phase one in 2018. It anticipates finishing phase two by Dec. 31, 2019.

"The roadway will be replaced in the southbound lanes only, but traffic will be affected in both directions," said Sean Shepard, Caltrans Project Manager.

Northbound and southbound daily lane closures will take place during the first four to six weeks and will be followed by long-term lane closures. Traffic will be restricted to a single lane in the southbound direction while two lanes will be available for northbound traffic.

"We understand construction may cause inconveniences to commuters and that nobody welcomes disruption," said John Hinton, Caltrans Area Construction Engineer for Siskiyou County, "but we are committed to informing the public and local stakeholders efficiently while we do our best to minimize inconveniences and disruption."

Also, long-term ramp closures with detours will include the southbound Mott Road on- and off-ramps and southbound Dunsmuir/Siskiyou Ave on- and off-ramps.

"Ramp closures will be required for the Dunsmuir Ave off-ramp as well," said Nicole Mallory, Caltrans Resident Engineer, "but these closures will be limited in duration, will be minimized to the extent feasible, and will only occur when the Dunsmuir/Siskiyou Ave ramps are open."
