For close to three decades, "Ol'" Bill Taylor has been selling cars at the intersection of Hopkins and San Antonio streets.
From the beginning, he realized that the intersection had problems.
"It's a dangerous intersection still and that's why when they first talked to me about the possibility of changing things up, I was in agreement," he said.
Taylor says the city originally proposed adding a third lane and realigning San Antonio street. City planners say those changes would create the need for another traffic light.
Now the city's plans call for a roundabout.
"The roundabout addresses the signal and also slows traffic down coming in from a commercial area," Richard Reynosa, senior project engineer, said.
The city is in the process of putting the finishing touches on two roundabouts on Cheatham Street. City leaders say they haven't had any issues at those intersections so far.
"It's also safer for pedestrians and bicyclists," Reynosa said.
But neighbors don't believe it will work at Hopkins and San Antonio and opponents are taking their fight to City Hall.
"I just don't see the logic here for a roundabout,” Taylor said. "We're trying as a last ditch effort to see if City Council will reconsider the roundabout idea."
San Marcos isn't the only Hays County city looking to roundabouts to solve their traffic problems. The City of Kyle and the Texas Department of Transportation will host a meeting this Wednesday to discuss a potential roundabout at the intersection of Farm to Market 1626 and Kohlers Crossing.
