The Pennsy Greenway is currently open in three segments between Calumet City, Illinois, and Schererville, Indiana. The northern portion begins at the southern end of the Burnham Greenway in Calumet City on the eastern edge of the Forest Preserve District of Cook County’s Green Lake Woods. The trail proceeds south to Bernice Road, crosses under I-80/94 and continues southeast through residential neighborhoods to just past the Illinois-Indiana state line. At Fisher Street, the trail links directly with Lake County's Monon Trail and a local bike path.
There is a short gap in the trail from Fisher Street to where the second segment of the trail begins at Calumet Avenue and 45th Street in Munster. From here, the Pennsy Greenway runs adjacent to the sprawling Centennial Park, a new golf course and residential developments. This section ends at E. 53rd Avenue/Main Street, but local bike paths allow for longer routes north, west and east.
The large gap from Main Street to E. Joliet Street is in the process of being abandoned by Norfolk Southern Railway, and there is local interest in acquiring the property to help complete the Pennsy Greenway. For now, the next open portion of trail begins 1 block south of E. Joliet Street at E. Wilhelm Street in Schererville. The greenway passes Redar Park, travels under US 30 and runs through a mix of industrial and residential properties before terminating at Rohrman Park’s baseball fields.
In the north, parking and direct trail access can be found at Green Lake Woods on the north side of 159th Street/US 6. The Lansing Community Garden also offers limited parking on Sherman Street.
For the trail segment in Munster, park at Centennial Park off Calumet Avenue. In Schererville, park in the large parking lot between E. Joliet Street and E. Wilhelm Street or at the lot on Reiplinger Road. Redar Park also has a large parking lot off Austin Avenue on Park Street. At the trail’s southern terminus, park at Rohrman Park on Rohrman Road.
