Ballinger CR 129 Pony Truss

Bad news;


A "suspicious" early Sunday morning fire destroyed a historic wooden and steel bridge over the Colorado River near Ballinger, fire officials said Monday.

It took the Ballinger Volunteer Fire Department five hours to extinguish the Sunday morning fire. The investigation into the cause has been turned over to the Texas Fire Marshal's office.

Firefighters from the Ballinger Volunteer Fire Department responded to a fire called in about 9:20 a.m. Sunday.

When the firefighters arrived, they realized it was the 12-Mile Bridge, an abandoned wooden and steel structure that crosses the Colorado River alongside a modern bridge at County Road 129.

Volunteer firefighter Todd Cleary said, "Smoke had been reported earlier, and when it was confirmed it was in our county, we responded. It took about five hours to extinguish the blaze."

A Ballinger firefighter on Monday said the bridge is beyond saving. All of the wood on the east side of the bridge was destroyed, he said.

The three-span bridge is about 400 feet long and 12 to 13 feet wide.

This bridge is open to pedestrian use. It also has a small county park and boat ramp next to it.

That would make sense.

With the fencing on the sides and good decking it looks as if it might be open to pedestrians?
