The architect behind the Lincoln Road–Pine River Bridge was the Michigan State Highway Department and its builder was Walter Willets. The bridge is notable for being a large early example of an arched through girder bridge in Michigan, and for sitting on substantially skewed abutments.[2] It was listed on the National Register of Historic Places in 1999.[3] HistoryThe Michigan State Highway Department first designed an arched through girder bridge in 1921, and built the first of them over the River Raisin at Tecumseh.[4] Later versions of the design followed; among the earliest was this bridge over the Pine River. The bridge was constructed for the M-46 trunkline[2] and designated number 291402.[4] In October 1921 the state contracted Walter Willets to construct the bridge. The bridge was completed the following year at a total cost of $18,186.15.[4] The bridge eventually suffered from severe spalling, and in 2009 it was demolished and replaced.[2] DescriptionThe 1922 Lincoln Road–Pine River Bridge had a single main span stretching {{convert|90|ft}}.[4] The bridge was {{convert|26|ft}} wide with a roadway width of {{convert|20|ft}}. It was constructed using two arched concrete through girders which sat on brackets projecting from concrete abutments. Twelve concrete floor beams ran between the girders to support the roadway. The sides of the bridge featured recessed panels and five arched cutouts.[4] The bridge served in essentially unaltered condition until it was demolished.
