The State Road and Tollway Authority (SRTA) is a government agency of the U.S. state of Georgia. It is responsible for financing transportation initiatives and operating the state's toll roads.

A proposal to merge SRTA and GRTA, and most of GDOT's functions into a new State Transportation Authority was presented in the 150th Georgia General Assembly, however later in the legislative session a much more moderate plan was passed in March 2009, instead.
