The Little Colorado River formed one of the most formidable obstacles to transcontinental travel across Arizona on Route 66. The Winslow Crossing of the Little Colorado River was one of the most important on the highway's length and was erected by Navajo County as the State Highway Department was in its formative years. In 1939, the Winslow Bridge was replaced with a girder bridge and one through truss span of the multi-span truss bridge was relocated to the Woodruff-Snowflake crossing to span the Little Colorado River on this local county road. The bridge is listed on the National Register of Historic Places. The bridge was rehabilitated using Federal transportation enhancement grant funds, Fedearl bridge rehabilitation funds, and Navajo County local funds.
