The state is putting a big rush on fixing up the pavement on the I-30 Trinity River Bridge where a couple of big potholes have slowed traffic in the past two weeks. Tex-DOT will get contracts out immediately and hopes to have crews on the job within two weeks. Traffic engineers insist the steel and columns supporting the 50-year-old span are fine. But the pavement is old and really needs to be replaced, so crews will do that in stages. Tex-DOT expects there will be overnight closures of one lane at a time. These are just stop-gap measures, though, because long-planned work a replacement bridge is expected to begin by late next year or early 2010.
