The massive amount of rain that fell Monday night and through Tuesday morning caused damage to a retaining wall at South I-35 and North Loop 363.
Crews were working to stabilize the wall Tuesday afternoon and had the interstate closed at Exit 304.
TxDOT said it would take a minimum of 2-3 hours to repair the damage. They advised drivers to take the 304 exit, turn right and drive the six miles before getting back on southbound I-35.
Northbound lanes were also slow beginning at FM 1237 and Pendleton Road in Troy. The rain caused flooding over the main lanes under the overpass.
As of 2 p.m., the water had cleared but the large amount of mud and debris still made that section of the highway impassable.
TxDOT estimated it would take 1-2 hours to get the lanes reopened.
Traffic was diverted to the access road through Troy then back onto the interstate.
