Bridge L7075 is a historic arch bridge in Hartford Township, Minnesota, United States. It was initially built around 1940 by the Works Progress Administration with a modular corrugated iron product called Multi Plate for the arches and a masonry façade. The bridge was expanded with a third arch around 1942. It was listed on the National Register of Historic Places as Bridge No. L7075 in 2016 for having local significance in the theme of engineering. It was nominated for being a distinctive example of the era's Multi Plate arch bridges and for the fine workmanship embodied in its WPA rustic architecture with Neoclassical detailing.
