Travelers around Texas need to be observant tomorrow.
In preparation for the upcoming hurricane season, TxDOT and DPS will stage a mock contraflow traffic exercise along three stretches of highway.
The highways and areas affected include... Interstate 45 from Ennis to Conroe, US 290 from Burton to Muschke Road, and Interstate 10 from Loop 1604 in San Antonio to Brookshire.
Traffic flow will not actually be affected, changed or modified during this exercise.
Motorists will notice additional TxDOT and DPS vehicles on the affected highways, especially near entrance and exit ramps, most of the day.
