I’ve been across that bridge a few times…walking it…maybe even driving it… way back in the mid-50’s when I drove my old “blue mirage” out to Ft. Monmouth, NJ, while in the army. Highway #30 has changed quite a bit over the years, going around some towns like Boone, Ralston, Scranton, Jefferson, Marshalltown, T-T, Woodbine, etc., but then businesses would spring up along the newer #30 route. RAG has travelled sections of old #30 quite often and now they have signs stating that this or some other county blacktop is the original Lincoln Highway.
Beebs, be careful out there on Lincoln Highway. Some of the older sections of it have no paved shoulder at all and I’ve biked those many years ago, but probably wouldn’t do it now~~~very dangerous…some of the newer sections might have just 18″ or so of shoulder…newer regulations to accomodate cyclists and hikers, thank goodness for that.
