Projects updated after September 20, 2017 NCTC meeting:

Safety Improvement on SR 174 Expanded from Maple Way to You Bet Road
This project proposes to realign curves, widen shoulders, add a left turn lane at Greenhorn Access Rd., and improve the clear recovery zone between Maple Way and You Bet Rd. on State Route (SR) 174 in Nevada County. The purpose of this project is to improve safety and operations for all users, including bicyclists and pedestrians. It will help reduce the number and severity of collisions on the existing highway. This project was amended into the 2014 State Highway Operations and Protection Program (SHOPP) in September 2014, with a revised total cost of $28,456,000, including Engineering, Environmental, Right-of-Way (R/W), and Construction. Circulation of the Draft Environmental Document (DED) was completed on June 2, 2016. A public meeting was held on June 9, 2016 at the Chicago Park School. During the meeting 46 people “signed-in” and the public comment period regarding the project/DED concluded on July 1, 2016. All public comments were answered and the Project Report and Environmental Document were completed on 9/2/2016 and Final Design started. Construction is scheduled summer 2019. An informational open house was held May 24, 2017 at Chicago Park School. During this meeting 95 people “signed-in” and updates on the status of the project and the R/W process were answered. The majority of those attending the meeting expressed that they were not happy with the proposed design and its impacts on their property or the general atmosphere of the “rural” feel of SR 174. The State has been getting emails expressing their dissatisfaction. We have had meetings with Nevada County Supervisor Heidi Hall regarding the project as well as a phone meeting with California Assemblyman Dahle. Ms. Hall requested more accident data which we are working on providing. Assemblyman Dahle had been contacted by several of his constituents that are opposed to the project and asked several questions regarding the project. He was appreciative of the information provided to him and was in support of this safety project. He commented that if just one life is saved by these changes the project was worth it. The State is continuing to answer people’s questions with assistance from NCTC staff. 
The “Save Hwy 174” group has organized in opposition to the project. The Nevada County Board of Supervisors has also sent a letter to the State in opposition to the project. Since the May 24, 2017 open house, Caltrans and NCTC staff have met with members of the group to discuss the design and the changes the group would like to see made to the project. A meeting was also held in Assemblyman Dahle’s office with Supervisor Hall attending by phone. In that meeting the State and the group were encouraged to find areas where compromise can be achieved. The State is planning a meeting with the Board to discuss the project, possibly at the Oct. 24, 2017 Board Meeting. We are also planning to meet with “Save Hwy 174” specific committees to further discuss possible compromises that can be made.
 
SR 174 Safety Improvement Project Fact Sheet from Caltrans Open House May 24, 2017

Widen SR 49 North of La Barr Meadows Project and Just Before McKnight Way Interchange
This project proposes to make this section of the highway a four-lane conventional access control highway with a continuous median/left turn lane, and 8-foot shoulders to be consistent with the highway to the north and to the south to improve traffic operations and safety.  The project is located south of Grass Valley in Nevada County, between PM 11.2, the north end of the SR 49/La Barr Meadows project, and PM 13.3, near the McKnight Way interchange. This project is programmed in the State Transportation Improvement Program (STIP) from the Regional Improvement Program (RIP). The Project Approval & Environmental Documentation (PA&ED) phase is programmed for $3 million, and the Plans, Specifications, and Estimates (PS&E) is also programmed for $3 million. Preliminary Engineering is taking place and field surveys are complete. An Open House was held on 8/5/15 at Grass Valley City Hall to present project information and project concept options to the public. Results from the meeting showed alternative option #4, 22-ft wide median freeway with median barrier and frontage roads, as the one the public favored most. Design is working on the preliminary preferred alternative option #4 and Right of Way is working on permits to enter for environmental field work. Environmental work has started including searching cultural survey data. A PDT meeting was held 6/19/17 to discuss the current status of the project and the large number of archeological sites that have been discovered throughout the project limits. More extensive archeological studies are going to be required to determine each site’s historical significance. This information is required to complete the environmental document. These studies are estimated to cost approx. $900,000. The PDT and NCTC staff are in agreement in moving forward with these studies so the environmental document can be completed. Caltrans will have another public meeting after the Draft Environmental Document is complete in spring of 2019 to present the alternatives to the public for comment and a preferred alternative will be selected.

Hot Mix Asphalt Overlay on SR 49 to the Yuba County Line
This project proposes to preserve and extend the life of the existing pavement and improve ride quality. The project limits extend from 1.2 miles north of the South Yuba River Bridge on SR 49 to the Yuba County line (approximately 9.4 miles).  This project proposes to Cold-in-Place Recycle (CIR) the existing pavement and the placement of a new HMA overlay.  All new HMA surfaces will also receive new striping.  This project was amended into the 2014 SHOPP on 11/07/14 for a total cost of $7,579,000, including Engineering, Environmental, R/W, and Construction.  The Project Report was completed on 3/15/16, and final design in September 2016. The Project has been awarded to Mercer Fraser Company. Construction on this project has begun.

SR 20 Safety Project from Smartsville Road to Mooney Flat Road
The purpose of this project is to reduce the number and severity of collisions along SR 20 in Nevada County from 0.1 mile east of White Cloud Campground to 0.9 miles west of Washington Road by upgrading the existing roadway to current standards. This project will realign portions of the existing highway, widening the existing highway to accommodate uniform 12 foot lanes and 8 foot shoulders. It will improve non-standard curves, improve vertical profile, increase sight distances, upgrade existing drainage facilities, and provide a 20 foot clear recovery zone. The project is in the beginning design and environmental process. Construction is estimated to begin during the summer of 2021.
The purpose of this project is to reduce the number and severity of collisions along SR 20 in Nevada County near Lowell Hill Road, approx. 2 miles east of Omega Rest Area. This project will realign portions of the existing highway, widening the existing highway to accommodate uniform 12 foot lanes and 8 foot shoulders. It will improve non-standard curves, improve vertical profile, increase sight distances, upgrade existing drainage facilities, and provide a 20 foot clear recovery zone. The project is in the beginning design and environmental process. Construction is estimated to begin during the summer of 2021.
The purpose of this project is to reduce the number and severity of collisions along SR 20 in Yuba and Nevada Counties from 0.2 mile east of Lower Smartsville Road to Mooney Flat Road by upgrading the existing roadway to current standards.  This project will realign a portion of the existing highway which includes building a new bridge, and widening the existing highway to accommodate uniform 12 foot lanes and 8 foot shoulders.  It will improve non-standard curves, improve vertical profile, increase sight distances, add turn pockets, upgrade existing drainage facilities, and provide a 20 foot clear recovery zone.  The current programmed amount is $28,780,000 which includes Engineering, Environmental, R/W, and Construction. The Project Report was completed on 1/29/2016. Final design and R/W work has started and is scheduled to be completed by spring 2018. This project is scheduled to go to construction during the fall of 2018.
