Drove Business US 24 in both Wabash and Peru last year for the purposes of clinching.
Wabash: Only signs are at the intersections with IN 15 and IN 13 indicating which direction BUS US 24 goes. No markers at all along the route nor at either connection with US 24, so I have no idea whether or not this route still exists. Nothing is signed as ALT US 24 despite what Google Maps says.
Peru: Signed only within the city limits of Peru. Not signed at either end.
Logansport: IN 435 no longer exists and hasn't for a while. IN 329 went away but came back.
