Weather permitting, TxDOT will be closing the various lanes of SH 121 both north and southbound between the exit from U.S. 75 to SH 121 and SH 5. Some of these lane closures will be rolling lane closures that will close the highway for short periods one direction at a time.

This closure will occur on Thursday, Jan. 15 from 9 a.m. to 4 p.m.

These closures are needed to prepare for a change in traffic configuration which will open a new direct connection ramp from southbound SH 121 to southbound U.S. 75.

Once the new traffic configuration is in place, the crossover access at the SH 121 and SH 5 intersection will be closed. The following alternate routes can be used until construction is complete on the new SH 121/U.S. 75 interchange.


U.S. 75 traffic headed to northbound SH 121 should exit at US 380, go east to SH 5, go north and travel to SH 121. From here, traffic will be able to turn right onto SH 121 to continue north.

Traffic headed to SH 121 southbound should exit from SH 121 at FM 455 and go west on FM 455. At U.S. 75, turn south.

Backups are expected and motorists are encouraged to seek alternate routes.
