Dyreson Road Bridge

This bridge has been completely restored and is once again open to traffic! The bridge received a full sandblasting and repainting, and a new timber/asphalt deck, wood guard rails inside the truss, and ARMCO railings and stop signs on either side. The bridge has been painted black. The only modification to the superstructure that I could find was that the stabilizer rods underneath were attached directly to the abutments rather than to the end floor beams. The wood guard rails are substantial, but they don't overpower the truss and allow for easy viewing of the lower chords. The bridge overall has retained its original appearance and functionality. The weight limit has been increased to 10 tons.
