For the time being, probably not for very long, the most congested stretch of highway in Texas is not in Houston.
Traffic on the West Loop has always been a mess and now it has a ranking from Texas transportation experts to match: No. 2.
Loop 610 through Uptown has lost its top spot among the state’s most congested freeway segments to Interstate 35 in downtown Austin, falling to second place according to an updated list of the 100-most clogged roadways released Tuesday by the Texas A&M Transportation Institute and Texas Department of Transportation.
It ends a four-year streak of the Loop between Interstate 10 and Interstate 69 being considered the worst in the state — a distinction the segment easily could reclaim as construction of the Loop 610 and I-69 interchange continues and slows traffic.
“Somebody has to win and somebody finishes second,” said David Schrank, senior research scientist at TTI one of the list’s authors. “It’s just math.”
This year, Schrank said, the math was razor-thin by TTI’s standards, using hours of delay per mile annually as the measurement. I-35 and Loop 610 were separated by fewer than 20,000 hours of delay, each topping 1.6 million total hours stuck behind the wheel.
Schrank and others have said COVID gives them a rare glimpse into what happens when commutes are curtailed and the effects that can have on traffic. In the Houston area, while some segments of highways are back to their pre-pandemic levels, others remain about 10 percent of the typical traffic volume compared to 2019.
The effect has been segments that came to a standstill for six or seven hours a day — three hours in the morning and evening — are at their worst instead for three or four hours. Traffic experts who look at telework and flexible times to travel to offices say that demonstrates their potential.
“We can potentially take those peak periods and whittle the shoulders off them,” Schrank said.
Still, in many cases congestion is always evolving, Schrank said. A few decades ago most trips into the office in Houston meant a trip from a suburban spot to a parking garage in the central business district. Now, tens of thousands of office jobs are in Uptown along Loop 610, at I-10 west of Houston in the Energy Corridor and sprouting up along the Grand Parkway and Sam Houston Tollway ringing the city.
“They might not have the truck traffic delays you see in the top 15, but those core commute routes are still on the list,” he said. “One can go up and one can go down, but they stay there.”
Yeah, don’t worry, Houston still dominates the list, even if the #1 spot is not ours, at least for now. I will just add that working from home and not contributing to any part of this problem for most of the year is something I will greatly miss when we go back to our office.
