Talk:U.S. Route 12 in Illinois

History additions
This article (and U.S. Route 41 in Illinois, U.S. Route 20 in Illinois) would be greatly helped by a general evaluation of the Chicagoland area in 1928, and especially 1938 when all of the U.S. Routes were kicked out of the immediate city area.

I can't imagine that Mannheim Road, La Grange Road, 95th Street, etc. were all that populated when the routes were moved to these roads, but why were they chosen? &mdash; Rob (  talk  ) 07:28, 6 June 2006 (UTC)

There are pedestrian underpasses under Route 12 just south of the intersection with Route 120 in Volo, just north of the south intersection with Old Rand Road at the south end of Wauconda, and in Lake Zurich, just south of the north intersection with Old Rand Road there. Would this information be useful in this article? Does anyone have any history as to why they were built? Does anyone know who "owns"/maintains the underpasses? DAW0001 (talk) 13:35, 6 May 2013 (UTC)
