Indiana State Route 129 is a north-south route running from Batesville south to Vevay, in southeastern Indiana. I have no clue how a number this far east in Indiana got a number ending in "29", but Indiana too neglects to follow its own rules. The northern end is in Batesville at Indiana Route 46, just south of Interstate 74; the southern end in Vevay is at Indiana Route 56.
My photo for Indiana Route 129 is the northbound trailblazer coming off of the 4-way intersection with Indiana Route 350. This is between Milan and Osgood. I drove home from southwestern Ohio in February 2017, and that gave me the chance to take this photo.
