NEAR BROWNSVILLE – Along Highway 48 in Cameron County, brown pelicans spend time around flying low and often, get stuck in the lanes of traffic.

A Texas Department of Transportation engineer believes the bridge is causing a turbulence that affects the bird.

“It’s called bad air or disruptions or low pressure,” says Homer Bazan. “It kind of pushes them down toward the highway.”

KRGV’s Christian von Preysing learned the agency plans to replace the side of the bridge. They also plan to place signs to warn drivers of volunteers assisting in the area.
