PLACER/NEVADA COUNTIES – Caltrans is alerting motorists to expect travel delays and one-way traffic control on State Route 193 (SR-193) in Placer County and State Route 20 (SR-20) in Nevada County for the next few weeks for various construction activities.

On Thursday, April 28 and Friday, April 29, work will continue to construct a westbound turnout on SR-193 just east of Whittington Drive. Construction crews will be clearing vegetation in shoulder areas and relocating fencing. Motorists should expect one-way traffic control and 20-minute travel delays between 6 a.m. and 6 p.m.

On SR-20, turnout construction will resume Monday, May 2 and Tuesday, May 3. The east- and westbound turnouts located just west of Conservation Road/Pine Needle Lane are scheduled to be repaved, with one-way traffic control and 20-minute travel delays expected between 6 a.m. and 6 p.m. Work is dependent on whether ground has sufficiently dried from recent storms.

The $2.8 million project is installing turnouts on SR-20 in Nevada County just west of Conservation Road/Pine Needle Lane and two turnouts on SR-193 in Placer County between Whittington Drive and Skyview Drive. Teichert Construction of Roseville is the prime contractor for the project with completion expected this summer.

In addition to turnout work on SR-20, one-way traffic control will be in effect weekdays from 6 a.m. to 6 p.m. in the Washington Road area for the Omega Curves Safety Improvement project. Grading work is expected to resume May 2 and continue for several weeks in this area. Motorists should expect 20-minute travel delays.

The $62.5 million Omega Curves project aims to improve safety and reduce collisions on SR-20 by realigning curves on two non-contiguous segments near White Cloud and Lowell Hill, widening shoulders, improving the highway’s sight distance and adding designated left-turn lanes near Conservation Road and Washington Road. In addition, three turnouts will be added where slow-moving vehicles can allow motorists to safely pass, while also serving as traffic-enforcement locations for the California Highway Patrol.

Granite Construction, Inc. of Sacramento is the prime contractor for the Omega Curves safety project, which is expected to be finished in fall 2023. Weather or other unexpected events may prolong construction activities.

Caltrans reminds motorists to “Be Work Zone Alert” and slow in construction zones for the safety of travelers and crews performing these improvements.
