Update: All lanes have been reopened, reports TxDOT.
Original Post: The Texas Department of Transportation says all southbound lanes of North Interstate 35 are closed just south of the U.S. 183 exit because of a major crash.
Traffic is being detoured to the access road.
Austin Police are not sure how long it will take to reopen the lanes.
