Interstate 64 and 57 will merge just before Exit 95 to Mt. Vernon.
Take exit 95 toward Mt. Vernon and turn East onto IL-15/Broadway.
Continue to follow IL-15/Broadway for approximately 3.5 miles.
Towards the outskirts of town, you will cross over two sets of railroad tracks. After the second set, merge into the left lane.

The road will then fork, with IL/15 continuing straight from the right lane and Fairfield Road slightly turning off to the left. Once you are on Fairfield Road, continue for approximately 3 miles and Green Hills will be located on the right side of the road.
