broken piece on Rhodes St. bridge

A broken board with a rusted metal clasp is lying on the Rhodes St. Bridge.  The broken board may be commemorating a historic bridge that once spanned Rt. 50 in Rosslyn.  The broken board might have been part of a covered wagon heading from Rosslyn to Oregon via Rt. 50 and the Oregon Trail.  The board may have been part of fortifications with which Rosslyn defended our nation's capital.
