Later this month, the speed limits on a portion of Loop 1604 will change, and in some instances, frequently change throughout the day with a new system being piloted by TxDOT.
Imagine driving on loop 1604 and a new digital speed limit sign on the side of the road changes from 60 to 55. The signs are a new variable speed limit system TxDOT is deploying here in San Antonio, in Eastland County and Waco. The system is used in other states like Florida.
TxDOT spokeswoman Laura Lopez said the system is designed as a safety measure.
