The High Trestle Trail connects Ankeny north to Slater and then east to Woodward. The section between Woodward and Madrid is the most notable part since it has a reconstructed railroad bridge. The bridge is 18 stories high. The trestle has been reshaped into an evolving pattern of squares to give a person riding through an illusion of passing through a tunnel. With my friends Brian and Zane, we biked the majority of the trail.
