Keep an eye on your speedometer if you are traveling in the westbound lanes of Loop 1604 this morning as the speed limit might be 70 mph, or not.

A plan from Texas Department of Transportation to enact variable speed limits along the loop between U.S. 281 and Interstate 10 goes into effect today.

As reported in the Express-News on June 25, the change is part of a pilot program where speed limits change depending on the flow of traffic.

While the current speed limit on that portion of Loop 1604 remains 70 mph, speeds could drop as low 30 mph during heavy congestion.

The testing phase of TxDOT's program will last for three months.
