A highway worker was hit by an 18-wheeler as he worked along Interstate 35 in Lacy Lakeview early Tuesday morning.

At around 2:10 a.m. Tuesday, Manuel Rivas, 42, of Houston, was working on the highway near mile marker 342 when an 18-wheeler heading north struck him.

Other site workers said the driver of a brown Ford dually pickup pulled alongside the truck-tractor and tried to get the driver’s attention so he would stop, but failed to do so.

The Lacy Lakeview officers and police in West and Hillsboro were not able to locate the truck-tractor.

Rivas was pronounced dead at Hillcrest Baptist Medical Center. His body was transported for autopsy at the Southwest Institute of Forensic Science, in Dallas.

Rivas was employed at a construction company that is contracted to the Texas Department of Transportation.

Department of Public Safety trooper D.L. Wilson said anyone with information about the pickup truck or the 18-wheeler is asked to call the DPS communications office at (254) 759-7131.
