The Texas Transportation Commission has approved a speed limit of 85 mph for a 41–mile toll road between two of the state's largest metropolitan areas —the Interstate 35 corridor between Austin and San Antonio. The new toll road is scheduled to open in November.
Opponents say the higher speed limit will give people leeway to drive enough faster.
“If you’re looking at an 85 mph speed limit, we could possibly see drivers going 95 to 100 miles per hour,” said Sandra Helin, president of the Southwestern Insurance Information Service, in an interview with the Los Angeles Times in June. “When you get to those speeds, your accidents are going to be a lot worse. You’re going to have a lot more fatalities,” she said.
A spokesman for the nonprofit Insurance Institute for Highway Safety agrees. “The research is clear that when speed limits go up, fatalities go up,” said Russ Rader. “You get there faster but the trade-off is more crashes and more highway deaths.”
A 2009 report in the American Journal of Public Health, cited by the AP, studied traffic fatalities in the U.S. from 1995 to 2005 and found that more than 12,500 deaths were attributable to increases in speed limits on all kinds of roads.
The study also said that rural highways showed a 9.1% increase in fatalities on roads where speed limits were raised, but did not cite specific numbers in those instances.
For most highways in the U.S., the maximum speed is 75 mph. Some highways in West Texas and Utah have 80 mph speed limits.
The Texas Legislature last year approved 85 mph limits for some new stretches of road. The strip of toll road running from Austin to Seguin, about 35 miles northeast of San Antonio, will be the first to allow that speed when it opens in November.
The Texas Transportation Commission, which is appointed by Gov. Rick Perry, approved the 85 mph speed limit at a public meeting on Aug. 30. Commissioners would not comment on their decision.
The state contract with the toll operator allows the state to collect a $67 million up-front cash payment or a percentage of the toll profits in the future if the speed limit is 80 mph or lower. At 85 mph, the cash payment balloons to $100 million or a higher percentage of toll revenues.
Texas Department of Transportation spokeswoman Veronica Beyer said, “We must continue to look for innovative ways to generate revenue and be good stewards of taxpayer dollars.”
Agency officials had previously said they would study the toll road’s topography, the speeds that most drivers were reaching, and the safety of access points and cross sections before approving the 85 mph speed limit.
“Safety is our top priority and tests have shown the designated speed is a safe one,” Beyer said.
During his daily commute from Round Rock, north of Austin, to his job in San Antonio, Steve Marcy sometimes uses another part of the toll road. The section he drives now has an 80 mph speed limit. Marcy said he'd be comfortable driving 85, but would be concerned about others driving vehicles that are not in good condition.
“A tire blowout (at 85 mph) could be a big hazard,” Marcy said.
Toll prices have not yet been set for the new section. Marcy predicted the higher speed limit would attract new drivers, but said most may not think it's worth paying the tolls.
“For most people I talk to, it’s a cost issue,” Marcy said.
