If Central Texas had a roller coaster for a roadway, this would be it. Steve Martin has driven the twists and turns of 2222 for the past 20 years.
A curve at Dry Creek Drive is the first drop in the roller coaster.
"During bad weather or icy weather, there's going to be some serious accidents right here on this corner,” Martin said.
Austin city crews are putting the final touches on a new traffic signal at the intersection. Extra lights are mounted high to alert drivers of what to expect.
"This curve is kind of rough, so I don't know if it will be too good for traffic," Martin said.
"People do need options to get in and out of their neighborhoods," Gary Schatz of the Austin Transportation Department said.
Schatz says as many as 140 cars an hour try to enter 2222 from the side street, but are often overwhelmed by the 2,700 cars coming from both directions on 2222, sometimes at speeds well above the 45 mile an hour speed limit.
"One of the criteria we look at is the number of crashes, the type of crash. We look at the volume of traffic going through the intersection," Schatz said.
Plans for the light pre-date a crash last February that killed KLBJ reporter Barbara McCarley, but data from the city shows this stretch of the highway is more prone to crashes than others.
Since this light is being put up on a blind curve, signs will be put up in each direction warning drivers of the new traffic signal.
"That gives people a chance to get used to, 'Oh, there's something different here,'" Schatz said.
While Schatz hopes it will warn drivers to be more cautious, Martin expects the opposite.
"I'm going to be expecting an accident. I'm going to be looking in my rearview mirror more often," Martin said.
Transportation officials expect to be done testing the light on 2222 in the next week or so. They say it will flash yellow for three days before switching to its regular cycle.
