The Twin Bridge Through Truss is located in Danville, Indiana.
This historic bridge was in very bad shape, with floor beams that were beyond repair and had to be replaced. The new floor beams were made just as the original beams were made, rather than standard I beam configuration, these beams were made of flat steel plate and steel angles all riveted together to form a very strong beam.
Besides the floor beams being built up riveted together, there were also many other rivets that had to be replaced on this structure Ross Brown, blacksmith from the Delphi, Indiana area was called on to help with this portion of the work. Blacksmithing is something of a lost art, but Ross always does a wonderful job.
Restoring a historic bridge such as this iron truss, is sometimes a challenge in just being able to access the area, and this bridge was no exception. With having all the floor material off of the steel beams, and then all the steel beams removed, it is a challenge to get all the new material out in place, sometimes requiring just hard, hand work, incorporating such tools as manual operated come a longs and block and tackle.
