Caltrans is reminding motorists to expect intermittent one-way traffic control on several Sierra highways through March for emergency tree removal operations.

After record-breaking winter storms in December coupled with high mountain winds, hundreds of trees along Sierra highways pose a hazard and need to be removed. Caltrans initiated a $3.7 million emergency contract with Tyrrell Resources, Inc. of Truckee to do the work.

Most tree removals will occur Monday through Friday from 7 a.m. to 5 p.m. Motorists should expect delays of up to 20 minutes or up to 30 minutes for larger trees.

Work next week is scheduled on the following highways:

  • State Route 20 (SR-20) in Nevada County from Scotts Flat Road to White Cloud Campground;
  • SR-49 in Yuba County from Marysville Road to Camp Pendola Road;
  • SR-193 in El Dorado County from Penobscot Road to Bear Creek Road;
  • Interstate 80 (I-80) from the SR-174 connection to Monte Vista. The I-80 work will require the closure of the #2 eastbound lane Monday through Wednesday and the #2 westbound lane Thursday and Friday.

District 3 is responsible for maintaining and operating 4,385 lane miles in 11 Sacramento Valley and Northern Sierra counties.
