HOUSTON — The Texas Department of Transportation has closed three westbound lanes on the Katy Freeway near Mason Road due to emergency repair.

The HOV lane is also impacted.

As of 6:15 a.m. Friday, the lanes had not reopened. They were supposed to open at 5 a.m.

TxDOT told KHOU 11 that they had already planned to do roadwork on this specific area starting Thursday night, but when crews started prepping on Wednesday night, they noticed cracks and a shift in the soil that were possibly dangerous. So, they decided to start the emergency repairs early.

If you're headed this way, please drive cautiously through the construction zone.

TxDOT says expect delays near Clay Road and Westpark as a result of the closure.
