The Illinois Department of Transportation is replacing a 1925 bridge in Pontiac, Ill., on old Route 4, which is a precursor to Route 66. The agency took considerable pains to make sure the new bridge looks like the old one. This story here explains it nicely. The construction is estimated to be finished by winter.
The newspaper had no photo of the bridge, but I’m almost certain it’s the one on this Illinois Route 66 Association document here. It’s listed about halfway down, listed under Pontiac, Ill. Preservationists John and Lenore Weiss showed it to us one day.
