A Wednesday morning collision last week just north of the intersection of U.S. Highway 287 and Walnut Grove Road has claimed the life of a Fort Worth man.

Midlothian police, fire and ambulance crews were dispatched to the 4100 block of Highway 287 at about 8:45 a.m. and found a silver Dodge Ram 1500 that had been struck in the side by a Peterbilt tractor-trailer hauling gravel.

The driver of the pickup was identified as Juan Calix, 40, of Fort Worth and he was pronounced dead at the scene by Justice of the Peace Curtis Polk.

Kevin Johnson of the Midlothian Police Department said an initial investigation has the pickup making an improper lane change in highway traffic.

“All vehicles were northbound on (Highway) 287 when the pickup attempted to make a lane change,” Johnson said. “This is based on what we see and from eyewitness reports of the accident.”

Johnson said the incident is under investigation.

Both vehicles were northbound on Highway 287 and had just gone through the intersection at Walnut Grove when the collision occurred.

The pickup was struck on the passenger side by the tractor-trailer and both vehicles came to rest more than 100-feet down the highway in the median.

“Nothing at this point indicates either vehicle was traveling at unsafe speeds,” Johnson said. “There was another 18-wheeler in traffic that was hit in the accident, but it received only minor damage.”

The Peterbilt was driven by David Reed of Fort Worth, who was driving for Sunset Transportation. Medical crews treated Reed for chest pains and emotional distress at the scene.

No one else was injured in the accident.

The accident snarled traffic on Highway 287 at the Smartstop Convenience Store for about two hours.
