The southbound side of Interstate 35 in Denton at Farm-to-Market Road 1173 reopened Tuesday evening after a closure of more than 13 hours.
A crash involving two semitrailers caused the shutdown early Tuesday morning.
The collision happened just after 4 a.m. Tuesday, Denton police said. Initially, both sides of the highway were closed, but the northbound side of the highway reopened at about 6:30 a.m.
The road closure had traffic backed up several exits. FM 1173 is just north of the I-35 split.
