State transportation officials are rolling out several changes to Interstate 35 construction zones in Central Texas in response to a string of major wrecks and deaths.
Lower speeds, rumble strips and more warning signs will mark work zones along I-35 in the Waco area and parts of Hill, Bell and Falls counties.
Some new 60-mph speed limit signs are up in Hill County, but most of the new safety features will go live in the spring, Texas Department of Transportation spokeswoman Jodi Wheatley said.
