Significance: The McCammon Bridge is the longest of the concrete tee-beam bridges built in Idaho between 1915 and 1945. It crosses the Portneaf River and the Union Pacific Railroad tracks. The bridge was originally part of U.S. 30 prior to Interstate 15. Since then, the bridge became an important link between U.S. 30 and the city of McCammon and was designated I-15 Business Loop. The bridge was listed eligible for the National Register of Historic Places in 1990.
