TransNet – Your Tax Dollars at Work! 

TransNet is the voter approved half-cent sales tax for San Diego region transportation projects. It is administered by the San Diego Association of Governments (SANDAG). During the 60 year life of the program, funds will be generated and distributed among highway, transit, and local road projects in approximately equal thirds.

***Please note: some project pages and links are currently experiencing technical difficulties. Thank you for your patience while we work on resolving these issues. If you need any assistance, please send a message through the Contact page.***
