Illinois Route 173 is an east-west state road that runs from Illinois Route 251 in Machesney Park east to Illinois Route 137 (Sheridan Road) in Zion near the Illinois-Wisconsin border. This is a distance of 79 miles (127 km).[2] On Interstate 94 (Tri-State Tollway) traveling south from Wisconsin, it is the second road seen which has an interchange at that location.
[edit] Route description
Illinois 173 travels across relatively hilly northern Illinois from the Rockford area to Zion. This area is more densely populated than other portions of rural Illinois. Illinois 173 is known as Rosecrans Road for a portion of the road.
As of 2006, an interchange is being constructed at Illinois 173 and Interstates 39/90 (Northwest Tollway). Completion is scheduled for Summer 2007.[3]
[edit] History
SBI Route 173 originally ran from Machesney Park to Zion, and remains so to this day. From 1972 to 1994 it also assumed a portion of what is now Illinois Route 137 north to the Wisconsin border.[1]
