What's left of Illinois 129 runs along an old alignment of US 66. An old bridge spanning the Mazon River and railroad tracks was demolished due to poor condition and never replaced. So IL129's southern end was pulled back to IL113.
Intersections from North to South:
IL129 begins at I-55...
and ends at IL113 in Braidwood.
It passes through these towns: Braidwood.
Notable places: Not much. It's still nice to know while you're driving on it that it was once the famed Route 66.
Northbound traffic on IL129 can't access I-55 southbound.
