Interstate 180 is an oddball Interstate corridor that is not up to full freeway standards. It is an expressway with mostly at-grade intersections between Interstate 80 and Lincolnway, although it does have some grade separations. At Lincolnway, the expressway portion transitions and diverges to a pair of one-way streets (Central Ave. and Warren Ave.). Another oddity about Interstate 180 is that is uses a standard diamond interchange with I-80 instead of an advanced 6-ramp or cloverleaf junction.
