This is at the exit for westbound Interstate 90 from Northbound Interstate 229. Note that both connections to Interstate 90 are labeled as exits; it doesn't flow smoothly into either direction. They mean it when they say "township road," as you'll see in the next couple of photos. Photos taken by Jay Maynard (01/05/02).

This picture shows the asphalt road after the Interstate 90 ramps at the end of the northbound Interstate 229 freeway. Photo taken by Jay Maynard (01/05/02).

This is the end of the asphalt road, about a quarter mile past the previous picture. The "township road" continues as a gravel road from this point forward. So in essence, Interstate 229 becomes a gravel road north of Interstate 90. Photo taken by Jay Maynard (01/05/02).
Perspective from County Road Southbound
The county road emerges as an unpaved road, gains pavement, and then changes into a divided highway. The Interstate 90 bridges are in the distance. This is the beginning of southbound Interstate 229. Photo taken by Jeff Morrison (06/26/06).
