The High Trestle Trail Bridge was transformed from an abandoned rail line into an iconic destination bridge for pedestrians and bicyclists along the High Trestle Trail between Madrid and Slater.  The art enhancements on the bridge recollect the coal mining history of the area. 

This bridge soars 130 feet over the Des Moines River Valley.  During daytime hours, breathtaking panoramic views of the valley and rolling hills can be seen from the bridge and overlooks, which provide safe rest intervals and feature interpretive wildlife and historical exhibits.  During the night time hours, illuminated crib frames mounted along the bridge provide a stunningly different experience.  Massive monoliths, located one-half mile apart at each end of the bridge and fashioned to mimic limestone bluffs with coal seams, announce the bridge as trail users approach from either direction.
