To ease traffic flow on southbound I-45, TxDOT is moving the Allen Parkway entrance ramp from the left side to the right. It's also redesigning the Houston Avenue ramp. Construction starts this weekend, and TxDOT's Danny Perez says some downtown commuters will have to change their familiar routes.

"So we're going to shut down the Allen Parkway entrance ramp to 45 southbound and also the Houston Avenue southbound entrance ramp to 45 southbound,” says Perez. “In addition to the bridge structure that ties in from Houston Avenue to the ramp."

To facilitate that work, the I-45 southbound lanes will be closed this weekend from I-10 to U.S. 59. As for construction, Perez says it will take a few months.

"The bridge itself will be done, we're looking at late September,” adds Perez. “The new structures will be open in late November or early December."

The price for the new ramps is $3.6 million, and Perez emphasizes the project is not part of TxDOT's bigger plan to totally remake I-45.

That project is expected to cost about $7 billion. It hasn't been funded yet and officials say it's still a few years away.
