Crews are putting the finishing touches on a new West Dallas bridge downtown, but need one more weekend closing of a stretch of Interstate 45, set to start at 9 p.m. Friday.

Both directions of the freeway will close until 5 a.m. Monday so workers can complete the bridge and repaint lane markings on I-45 northbound, according to the Texas Department of Transportation.

“We’re getting close,” said Danny Perez, spokesman for TxDOT in Houston. “We may have lane closures here and there to get everything done.”

The original bridge was struck in September by truck carrying a piece of heavy machinery. The driver, who was cited, was the latest in a series of hits the bridge has taken over the past decade. The September strike did enough damage that engineers said the span needed to be replaced.

TxDOT changed a contract with a nearby project rebuilding the entrance ramps from Allen Parkway and Houston Avenue to southbound I-45.

The ramps, as well as the bridge, are expected to open later this month or early January, Perez said.
