NEVADA COUNTY – Major roadway improvements to State Route 20 (SR-20) continue in Nevada County with travel delays and one-way traffic control at multiple locations anticipated through the summer and fall months.

Motorists should expect 20-minute travel delays between 6 a.m. and 6 p.m. weekdays at multiple locations along a 14-mile stretch of highway between Conservation Road and Lowell Hill. Crews are installing or rehabilitating drainage, performing earth work to widen sections of the roadway and preparing for major dirt fill work to begin.

The work is part of the $62.5 million Omega Curves project, which 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 completed in fall 2023. The schedule is subject to change due to weather, equipment availability or other unexpected events. For project updates, please visit www.OmegaCurves20.com.

Caltrans reminds motorists to “Be Work Zone Alert” and slow in construction zones for the safety of travelers and crews performing these improvements. The department will issue construction updates on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3.
