Comprehensive TransNet Projects

TransNet Keeps San Diego Moving

Since 1988, TransNet, the half-cent sales tax for local transportation projects has been instrumental in expanding the transportation system, reducing traffic congestion, and bringing critical transit projects to life.

The 2015 TransNet Update brochure serves as an annual snapshot of the program's progress.

In November 2004, 67 percent of voters approved a 40-year extension of TransNet, which will generate funds for public transit, highway, and local street and road improvements. SANDAG leverages these funds with state and federal resources to improve the region’s transportation infrastructure and tackle growing traffic congestion head-on.

Partnering with Caltrans, MTS, and NCTD, SANDAG is advancing several projects. Through the aggressive Early Action Program, a variety of high-priority transportation projects have been accelerated. These major construction and infrastructure projects include I-5; I-15; I-805; SR 52 and SR 76; the Mid-Coast Corridor Transit Project (Trolley) from Old Town to the University of California, San Diego campus and the University City community; the Super Loop Transit Project, also in the University City community; the I-15 Managed Lanes and Bus Rapid Transit (BRT) service from Escondido to San Diego; and the South Bay BRT from Otay Ranch to downtown San Diego via I-805.

During the life of this 40-year extension, major highway projects along Interstates 5, 8, 15, and 805 as well as State Routes 52, 54, 56, 67, 75, 76, 78, 94, 125, and 905 will receive funding. TransNet also will support a robust public transit system. An $850 million environmental mitigation program and a $280 million smart growth incentive program make TransNet a truly comprehensive funding mechanism.

A key component of TransNet is public accountability. The revolutionary TransNet Dashboard gives residents timely information on how their tax dollars are being spent. This interactive tool is a key element of the comprehensive website — the region’s window to in-depth information on the TransNet Early Action Program.

The Independent Taxpayer Oversight Committee was created to monitor the expenditure of TransNet funds. In addition, SANDAG issues an annual report to keep the public updated on the progress of TransNet funded projects.
