One of Georgia’s top transportation officials is leaving to take a job in the private sector.

Chris Tomlinson is executive director of three Georgia transportation agencies – the State Road and Tollway Authority (SRTA), the Georgia Regional Transportation Authority (GRTA) and the Atlanta-Region Transit Link Authority (the ATL Board). He’s leaving after 24 years in state government, including nine in his current position.

Tomlinson will leave in May. The agencies did not announce where he will be working next.

“Serving as the executive director for the state of Georgia’s mobility authorities has been the most challenging and fulfilling experience of my professional career,” Tomlinson said in announcing his departure.

Tomlinson has had the unusual task of managing three agencies simultaneously through a time of substantial change.

For years GRTA operated the state’s Xpress commuter bus network, and Tomlinson oversaw the replacement or refurbishment of nearly 60% of the original bus fleet. He later managed the transition of the Xpress bus network from GRTA to SRTA and then to the ATL Board. GRTA also reviews proposals for large regional commercial and residential developments, analyzing their impact on traffic.

SRTA operates metro Atlanta’s growing network of toll lanes. Tomlinson oversaw the addition of three new tolled lanes, and SRTA expanded to more than one million customers with Peach Passes. Under his leadership, the agency also negotiated agreements with Florida and North Carolina to allow Georgia residents with Peach Passes to use those states’ toll lanes, and vice versa.

Tomlinson’s responsibilities expanded in 2018, when the General Assembly created the ATL Board to oversee transit planning and funding in metro Atlanta. Among other things, the agency has created an evolving regional transit plan and is creating a mobile app that would allow passengers to plan trips across multiple transit operators. The agency’s ultimate goal is to create a more seamless metro transit system.

Gov. Brian Kemp will appoint the next director of the agencies.

“Chris has been a valued member of the team and a key leader in the transportation sector within Georgia and nationally,” Kemp said.
