The Texas Department of Transportation will build new ramps from Houston Avenue and Allen Parkway onto Interstate 45 southbound to improve traffic flow and safety. Construction begins the evening of July 8 and will last until the end of the year.

Ramps from Houston Avenue southbound and Allen Parkway eastbound onto I-45 southbound will close at 7:30 p.m. on July 8. All main lanes on I-45 southbound will close at Interstate 10 from July 8 at 9 p.m. until July 11 at 5 a.m.

With the new entrance ramp, cars will enter into the right lane of I-45 southbound instead of the left lane, which currently causes traffic on the highway to slow and bottleneck.

To accommodate the new entrance ramps, the connecting bridge before the Houston Avenue southbound entrance ramp also will be reconstructed. The bridge is expected to be complete in late September or early October, while the entrance ramps are expected to open in late November or early December.

Nearly a year ago, the city of Houston began construction on Allen Parkway in an effort to make the busy road safer for drivers and pedestrians. The $11 million project is adding a U-turn bridge at Waugh Drive, new stoplights and crosswalks at Gillette, Taft and Dunlavy streets, as well as 175 new parking spaces in the current westbound lanes between Montrose and I-45. Once completed, speed limits will also be reduced.
