There are so many reasons to preserve this beautiful structure, and I am happy that MNDOT and Washington County both recognize its historical and aesthetic value. First, the bridge is constructed of wrought iron, which fell out of fashion long before the turn of the 20th century. Wrought iron takes much longer to corrode than steel does, and in that respect, lasts much longer (which explains the low levels of rust on the bridge). However, steel is lighter, stronger, and easier to work with than wrought iron and ultimately replaced it as the material of choice by the end of the 1800's. Second, every member of this bridge is built up with either V-lacing or lattice, features that to me makes a truss bridge much more beautiful and artistic in appearance than one made up of rolled I-beams or built-up angles. This bridge has V-lacing on both the top and the bottom of the upper chord, which also was gone by the turn of the century--most bridge builders and designers had enclosed the upper chords on all but the bottom side, using V-lacing, lattice (or X-bracing), or batten plates. The bridge's silver main chords and black intermediate verticals and diagonals add to the visual appeal. Its one-lane wood deck is in excellent condition, and the wood substructure also appears to be in good shape. The substructure and steel approaches are not part of the original structure--they were added in 1937 when the bridge was moved to this very beautiful and scenic part of the state. As of now, the bridge has been removed and is in the process of being restored in preparation of its move to Washington County, where with proper care, it should stand for another 133 years!!
