NVTA Receives $25 Million to Relieve Traffic Congestion at Soscol Junction
The Soscol Junction Project is now fully funded
NAPA — Napa Valley Transportation Authority has received $25 million under the competitive Senate Bill 1 Solutions for Congested Corridor (SCC) grant to improve the intersection of Highways 29 and 221 in south Napa County, known as Soscol Junction.
Soscol Junction was ranked the second highest out of 21 projects submitted totaling $1.3 billion in requested funds. The California Transportation Commission approved 7 projects for a total of $500 million available from the SCC program on December 2. Soscol Junction scored high for its ability
to reduce vehicle hours of delay by 90% and CO2 emissions by 94,000 tons over the next 20 years.
Soscol Junction has long been NVTA’s most needed transportation improvement in south Napa County. The Project will remove the traffic signal and replace it with a north-south free flowing overpass on Highway 29 and double roundabouts at-grade allowing for turning movements in all directions for all modes. The Project will now serve as a major gateway in welcoming visitors and residents into Napa. It will also improve a critical evacuation route in the event of wildfires and other emergencies for both Napa and Sonoma Counties.
Soscol Junction will improve safety by reducing head-on collisions by 90% and all collision types by 66%. The Project will also provide safe movement through the intersection for bicyclists and pedestrians by providing a dedicated class I shared-use path around the intersection. The class I path will connect to a class II facility on Devlin Road south of the intersection, and eventually align with the planned Vine Trail class I facility that is to be constructed adjacent to Devlin Road. Vine Transit regional routes that connect to Vallejo Ferry, El Cerrito Del Norte BART and Amtrak/Capitol Corridor in Suisun City all use this intersection and the improvements will save an average of 2.6 hours in daily running times.
By eliminating a major bottleneck in south Napa County, this Project will encourage employment and economic growth. The Project will save $23.8 million in avoided fatalities, injuries and economic costs related to property damage and $411 million in travel time savings and is anticipated to create
1,050 new jobs.
NVTA’s award of $25 million in Solutions for Congested Corridor funds will match a mix of State Transportation Improvement Program, Local Partnership Program and local developer fees to fully fund the $64 million dollar project. The project is currently at 65% design with anticipated design completion by summer 2021, and is on schedule to break ground in summer 2022.
