SR 89 Mousehole Truckee
SR 89 is a major artery for vehicles traveling from I-80 to Lake Tahoe and several major recreation facilities in the area. The current Union Pacific Railroad underpass structure on SR 89 in Truckee, known locally as the "Mousehole," has long been the subject of discussion regarding its inadequacies. The structure was completed in 1928 by the U.S. Bureau of Public Roads. It has become a focal point for traffic congestion and needs improvements to provide safe pedestrian and bicycle access. Pedestrians who use the route to access shopping nearby have been observed running through the Mousehole to avoid conflict with cars. Others climb up and over the 25-foot-high railroad embankment rather than risk walking through the underpass.
The Town of Truckee (as lead agency), Caltrans, and the Nevada County Transportation Commission are providing funding to develop a project to improve traffic flow and safety at the Mousehole. Caltrans assembled a Project Development Team for this project, and after looking at several alternatives, it was determined that due to the high cost of widening the existing vehicle tunnel or adding a new tunnel, the scope of work was then focused on constructing a Pedestrian/Bicycle Undercrossing Tunnel on the east side of SR 89 between West River Street and Deerfield Drive. A 12-foot-wide by 10-foot-high concrete tunnel for pedestrian and bicycle use is being constructed beneath the Union Pacific Railroad tracks east of the existing vehicle tunnel. In order to construct the project, Caltrans provided $4.4 million from the State Highway Operation and Protection Program (SHOPP) and $570,000 of toll credits to be used for federal matching purposes. NCTC programmed and the California Transportation Commission approved an allocation on June 25, 2014 for $3.132 million in State Transportation Improvement Program (STIP) funds. Truckee is providing $350,000 from its traffic impact fee fund. Based on current estimates, project construction was underfunded by $1.5 million, so Truckee submitted an application for a federal grant from the TIGER 2013 program in that amount and was awarded the amount needed. The funds were obligated on June 27, 2014. The Town received authorization to proceed with construction on June 30, 2014 and the project went out to bid in August. The Town awarded the construction contract to Gordon N. Ball, Inc. on September 23, 2014 in the amount of $7,870,230 with a contingency budget of 10% or $787,000.

Truckee River Legacy Trail
The Truckee River Legacy Trial is a series of planned trails that locals and tourists alike enjoy year-round. The Town of Truckee adopted a Trails and Bikeways Master Plan, which provides detailed guidelines for the development of over 130 miles within the Town. The Truckee River Legacy Trail is a high priority trail. When complete, this trail will connect the Donner Memorial State Park to the Glenshire neighborhood. The majority of the route will parallel the Truckee River. Phase 1 and 2 of the Truckee River Legacy Trail was completed in the summer of 2009 and Phase 3A was completed in 2010. Phase 3B opened on August 8, 2014 (see invitation below to the opening ceremony). Phase 4 and 5 are segments to be completed in the future. For more details, click on the Truckee River Legacy Trail link below.

Truckee-Capital Preventive Maintenance (CAPM)
This project proposes to preserve the pavement on SR 89 in Nevada County from PM 1.2, just north of I-80, to the Sierra County line. It will preserve the existing pavement by Cold-in-Place recycling followed by HMA overlay. New striping and replacement of existing guardrail will also take place. This project was programmed in the 2012 SHOPP for $6,185,000 including Engineering, Environmental, Right-of-Way, and Construction. Bids opened on 10/23/14, and the construction contract was awarded to Granite Construction for $3,966,966. Construction work started on 7/7/15 and was completed in November.
Operational Improvements at Smith Road and SR 49
This project will construct a right-turn pocket lane on southbound SR 49 with a standard public road approach that is tapered with 4 foot shoulders. Funding is from the SHOPP Minor B Program. Design and Environmental studies are complete. Bids opened on 10/27/15 and the contract was awarded to Patterson Taber General Engineering Inc. for $188,661. Construction is scheduled to begin by mid-June 2016. Construction Capital = $280,000.
Safety Improvement on SR 174 Expanded from Maple Way to You Bet Road
This project proposes to realign two curves, widen shoulders, add a left turn lane at Greenhorn Access Road, and improve the clear recovery zone between Maple Way and You Bet Road on 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. The project was amended into the 2014 SHOPP in September 2014, with a revised total cost of $28,456,000, including Engineering, Environmental, Right-of-Way, and Construction. Preliminary Engineering work and Environmental studies continue to take place. Re-evaluation of accidents within the vicinity of this project confirmed the existence of collision patterns to justify increasing the project limits. A Project Change Request was approved to increase the project limits to Post Miles 2.7 to 4.6 with a new total cost of $28,456,000. Circulation of the Draft Environmental Document and Draft Project Report is scheduled to begin on June 2, 2016. Construction is planned to start in FY 2018/19. An Open House was conducted by Caltrans on May 7th at the Peardale Fire Station to share information with the public about the project. A second public meeting was held on June 9, 2016 at the Chicago Park School.
Widen SR 49 North of La Barr Meadows Project and Just Before McKnight Way Interchange
This project proposes to widen SR 49 to a four-lane conventional access control highway with a continuous median/left-turn lane, and 8-foot shoulders 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 SR 49/La Barr Meadows project, and PM 13.3, near the McKnight Way interchange. The 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) phase is also programmed for $3 million. Preliminary Engineering and Environmental work is taking place and field surveys are complete. An Open House was held on August 5, 2015 at Grass Valley City Hall to present project information and project concept options to the public. Results from the meeting showed Option #4, 22-ft. wide median freeway with median barrier and frontage roads, as the one the public favored most.
