September 2, 2008: As of 2012, the south end of IA 32 in Dubuque is/was US 20’s only at-grade intersection with a signed state route east of IA 110 in Sac County.
I figure this is worth an attempt at crowdsourcing.
Completion of the Southwest Arterial was suppose to trigger the transfer of jurisdiction of highways in Dubuque — the surface streets for US 52/IA 3 heading northwest from downtown and also the Northwest Arterial, aka IA 32.
A few months later, street signs were still up, although they have since been greened-out on the US 61/151 exit signs. The Iowa DOT was also a bit busy with replacing signs all over the state that had been flattened/snapped by the derecho.
If anyone has been in the Dubuque area in the past few months, are the signs on the arterial, and also Central/White streets, still up? If not, trying to narrow to at least a month would be nice for record purposes.
