Nevada Placer 20 CAPM Project

Nevada Placer 20 CAPM Project

The California Department of Transportation (Caltrans) proposes this Capital Preventative Maintenance (CAPM) project on State Route 20 located in both Nevada and Placer counties at three locations from East of Dow Road to Interstate 80 from Post Mile (PM) 20.00 to PM 46.12 (Figure 1–Project Vicinity Map). The three project locations are as follows: • Location 1: In Nevada County, near Nevada City and Emigrant Gap from east of Dow Road to the Placer County line (PMs 20.00 to 41.28). Work will be excluded from PMs 25.6 to 25.9, 29.7 to 30.9, 31.7 to 31.9, and 37.0 to 39.8 due to the Omega Curve Project which realigns a portion of SR 20. • Location 2: In Placer County, from the Nevada County line to east of Lake Spaulding Road (PMs 41.28 to 43.87). • Location 3: In Nevada County, from east of Lake Spaulding Road to I-80 (PMs 43.87 to 46.12). The project proposes pavement rehabilitation along the length of the project which includes cold plane and overlay of existing pavement, shoulder backing, pavement digouts, striping and rumble strips (Appendix A–Project Layouts). The project would also rehabilitate existing drainage systems and address flooding issues at the intersection of SR 20 and Scotts Flat Road (PM 23.38). Other work includes replacing non-standard Metal Beam Guardrail (MBGR) with Midwest Guardrail System (MGS) and vegetation control, upgrades to roadside signs, and upgrades to Transportation Management Systems (TMS) elements. This project would also include fire hardening to facilitate best practices for incorporating roadside fire fuel reduction. Fire hardening would create roadside fuel reduction along state owned structures.
