Background on the High Trestle Trail and bridge:
The High Trestle Trail is built on a former railroad bed, previously owned by Union Pacific Railroad.
The trail is famous for its 13-story and 1/2 mile long bridge over the Des Moines River, located between Madrid and Woodward in Boone County.
There are six overlooks on the bridge with interpretive panels that highlight the region's cultural and natural history.
The trail was designed by Snyder & Associates. The bridge was designed by Snyder & Associates and Shuck-Britson, Inc.. The artistic enhancements were designed by Dahlquist Art Studios/ RDG Planning & Design
At each end of the ½ mile long bridge are four 42’ tall artistic towers. The dark bands represent geologic coal veins found in area limestone deposits
41 steel “frames” over the bridge represent support cribs within an historic coal mine
Interpretive information panels are located on the bridge and at the overlook
