Document Description
The California Department of Transportation, in cooperation with the San Joaquin Council of Governments, proposes to install managed lanes on Interstate 205 through the City of Tracy, accommodate transit hubs, and improve interchanges between postmiles R1.7 on Interstate 580 and R13.5 on Interstate 5. The project limits extend from the Interstate 580 and the West Grant Line Road interchange in Alameda County to the Interstate 205 and the Interstate 5 interchange in San Joaquin County. Managed lanes are highway lanes that are actively managed to respond to an area’s rapid growth. Interstate 205 in the City of Tracy has been identified as an area of heavy congestion resulting from high truck volumes and commuters that travel to and from the Bay Area. Examples of managed lanes being considered for the proposed project would be high occupancy-vehicle lanes, transit lanes, and express (or toll) lanes. The project is proposing one no build alternative and four build alternatives. Alternative 1 would not build and the area would be left as is. Three of the four build alternatives would involve widening. Alternative 2 would involve partial widening. Alternative 3 would not involve widening but would convert an existing lane into a high-occupancy vehicle lane. Alternatives 4 and 5 would involve widening the length of the project area and would leave a 60-foot-wide median space open for future transit improvements. Local road overcrossings and undercrossings, and interchanges would be altered or reconfigured, if necessary, based on the alternative. Each build alternative may include detention or retention basins, access roads, and up to four transit hubs. Transit hubs features may include park-and-ride lots, electric vehicle charging stations, bus stops and train stops. Locations for transit hubs would be determined in coordination with stakeholders that include but are not limited to the following: Federal Highways Administration, Caltrans, Valley Link, San Joaquin Council of Governments, City of Tracy, Community of Mountain House, Alameda County, San Joaquin County, local transit, and the interested public to improve access to the transit facility and to avoid precluding connectivity to the local communities. The proposed project could construct facilities within the right-of-way, such as rail stops, to accommodate connection to the corridor, but may or may not construct the actual transit hubs.
