Gwinnett could get bus rapid transit for a fraction of MARTA’s cost

Though many residents would welcome a MARTA commuter rail expansion into Gwinnett County, some local officials may be warming to a mass transit alternative that could cost substantially less: bus rapid transit.

As The Atlanta Journal-Constitution has reported, a 2015 poll found half of likely Gwinnett voters would pay a 1-cent sales tax to bring MARTA to Georgia's second-largest county. It was a popular topic at some recent public meetings on the county's future transportation needs.

Gwinnett officials have been cool to recent calls for a public vote on MARTA. But they have touted bus rapid transit as an alternative – without actually endorsing it.

In her "state of the county" speech in February, County Commission Chairwoman Charlotte Nash offered a vision of Gwinnett's future that included artist renderings of a bus rapid transit system serving Infinite Energy Center, Gwinnett Place and Lilburn. On Tuesday commissioners got a briefing that showed Gwinnett could build a bus rapid transit system for a tenth of the price of a MARTA expansion.

Bus rapid transit mimics passenger rail service: Commuters board at transit stations, and the buses usually travel in dedicated lanes.

Currently, there are no bus rapid transit systems in Georgia. But Cobb County plans a $500 million BRT system along U.S. 41, and cities elsewhere – including Los Angeles, Cleveland and Raleigh – have embraced it.

At Tuesday’s briefing, Gwinnett Transportation Director Alan Chapman provided cost estimates for mass transit systems stretching from the Doraville MARTA station along I-85 to the Mall of Georgia and along Ga. 316 to Lawrenceville. A bus rapid transit system would cost about $660 million, light rail would cost nearly $3.4 billion and MARTA-style heavy rail would cost more than $7 billion.

Chapman said the estimates are very rough, based on the average cost per mile of projects elsewhere. They don’t include operating costs.

He also said building a bus rapid transit system could take five to nine years, while a rail system could take substantially longer.

Some commissioners expressed skepticism about an investment in rail at a time when transportation technology – think driverless cars – is evolving rapidly.

“You’re talking 30 years to put some of this on the ground,” said Commissioner Tommy Hunter. “You have to spend $1.7 billion to find out you didn’t need it.”

But none of the commissioners endorsed bus rapid transit, either. Even Nash has not said she’d support such a system.

“I’m holding out for teleportation,” she said Tuesday.
