Description 

This large steel trestle was built in 1913 and served into the 1970s, before the Saylorville Reservoir project necessitated its removal ca. 1973. The bridge's concrete footing pads and steel towers were not designed for submergence, which would happen when high waters backed up the channel. The Iowa Corps of Engineers constructed a new DPG bridge atop large, modern concrete piers designed to allow for inundation. One of the original bridge's concrete abutments was left in place, and today it functions as a lookout platform for viewing the current day High Trestle Trail Bridge.
