BGCM - Orofino Creek Bridge

Street View 


This is a rare Northern Pacific designed shallow floor plate-lattice through girder of 1895. It was originally installed at Lighting Creek on the NP mainline at Clark Fork Idaho, and carried a cast plate identifying it as such, into the 1970s. Original Cooper engine rating was about E-30, but it may have been strengthened.
