All northbound and southbound main lanes of I-69 at Loop 610 will be closed throughout the upcoming weekend, the Texas Department of Transportation announced Aug. 18.

From Aug. 20 at 9 p.m. until Aug. 23 at 5 a.m., the lanes will be closed as crews continue construction on the new I-69 northbound connector ramp to Loop 610 northbound, which spans over the main lanes of I-69, according to the news release. The ramp is scheduled to open later this year.

Motorists should expect delays and may want to consider an alternate route. Police will be on-site to assist with traffic control.

The closure comes as crews work on the $259 million I-69/Loop 610 interchange project, which seeks to significantly enhance safety and improve mobility by widening the connector ramps to two lanes, increasing sight distances and providing remedies to eliminate weaving.
