Construction on the concrete makeover of several Humble, TX, roads recently began as part of the city’s 2016 Concrete Pavement Improvement Plan. Asphalt-paved roads will be converted to 6 inches of concrete pavement. Curbs on some streets and intersections will also be converted. Construction is expected to conclude in early 2018 and provide more long-term solutions for Humble infrastructure, said Public Works Director Barry Brock. "[Asphalt] is good for 15-20 years and [concrete] is good for 40-50 years," Brock said.
