This bridge was bypassed with a new alignment and bridge to East of old route in 1980's. The "Michigan Road" passed through here in the mid 1800's, allowing travelers to go from Indy and points South all the way to Michigan via Logansport, Rochester, and Michigan City. At one time the road was laid with wooden planks due to problems with mud and swampy land inhibiting early travelers of this road. Just South of the old bridge, those "corduroy" planks sprang saplings at some point, and large Sycamore trees grew along both side of the roadway. In the early days of the automobile, it wasn't a problem, but as time went by and larger vehicles began to appear, the narrow confines of this roadway became a safety issue. I can attest how many close call my family had with semi's passing us in this stretch as we neared the bridge. The state eventually made it a state historic site complete with a official plaque denoting "Sycamore Row", and the highway was made to bypass the old road. Soon after completion of the new segment to it's terminus with State Road 218 (West) which is just North of the creek, the old bridge came down. Today not even the abutments remain, but the Sycamore trees are still there to see. Funny thing is old SR 218 originally intersected with SR 29 just South of Sycamore Row, and it's Westward lane is barely noticable today as well, though I have been told there are still old road signs along that ROW that are protected by the farmer who guards his land with paranoia.
This site tells about this famous "Michigan Road" throwback and mentions the bridge as well. http://hoosierhappenings.blogspot.com/2009/04/sycamore-row.h...
