Parma is on Old US 12, which today is known as Michigan Avenue when it runs through Parma (and most of Southern Michigan). Today, the village has two exits on I-94, which replaced US 12 as the primary route from Detroit to Chicago when the Interstate highway system was built. The segment of I-94 that services Parma was originally part of the US 12 bypass, a freeway built prior to the Interstate system that allowed motorists to bypass Jackson and Parma. This is the oldest segment of I-94, beginning at Sargent Road in East Jackson and running west to Michigan Avenue outside of Parma. This older segment of the road is identifiable by its median, which is significantly narrower than the rest of I-94.
