what's the story about these people, and this bridge?
Some years ago as a student there I determined that a Volkswagen traveling at a high rate of speed could become air born at the apex of this bridge.
Forty years ago this was one of two roads that allowed one to cross the tracks when a train was present. They build a third, then closed this one. At least they preserved it in place.
A well known family in Rolla. From the city website:
"Lanning Wooden Bridge Park
The City's smallest developed park, Lanning Wooden Bridge Park is .03 acres at the corner of 4th and Main, and offers a pleasant spot to just sit in the shade, visit the historic wooden railroad bridge, or take a stroll over the bridge to the 1860's courthouse. The park was recently renamed to honor the Lanning family of Rolla, who have contributed much of the funding to develop and landscape the park."
This bridge was probably saved through their efforts.
