TYLER, Texas — The city’s newest subcontractor is stuck. Flynn is surveying more than 90 miles of sidewalks across Tyler to assess their compliance with the Americans with Disabilities Act. Perhaps that perfect solution never will, but in Tyler, Texas, a city of 113,000 people in the state’s northeastern corner, city officials have stopped chasing perfect. Those pedestrians, Howell says, are often pushed into the streets because of a lack of safe, accessible sidewalks. That’s relatively smooth sailing, “until I run into the old sidewalk,” he says.
