Caltrans is beginning vegetation removal Wednesday on State Route 20 (SR-20) in Nevada County prior to the start of major construction work on the Omega Curves Safety Improvement project.
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.
