The Monon Trail (known as the Monon Greenway in Carmel) is a rail trail located entirely within the U.S. state of Indiana. It runs along the main line of the Monon Railroad, a popular railroad line connecting the cities of Chicago and Indianapolis with stops at major locations. After the decline of railroad travel and the sale of the company in 1987,[2] the portion of the line between Indianapolis and Delphi, Indiana, was abandoned.[3][4]
In Northwest Indiana, the trail is 4.4 miles (7.1km) long, running through Lake County from Munster to Hammond. In the Indianapolis area, the trail consists of 28.5 miles (45.9km) running through Hamilton and Marion counties, connecting Indianapolis, Carmel, Westfield, and Sheridan.[5]
The first portions of the trail were created in the late 1990s, but it has been consistently extended in both of its segments since then. The trail is a shared use path complete with trailheads, park amenities and local attractions near it.[6][7]
Northwest Indiana segment
Northwest Indiana's portion of the Monon covers 4.4 miles (7.1km), starting at the Pennsy Greenway near the Illinois–Indiana border in Munster, and running north to the Erie Lackawanna Trailhead in downtown Hammond.[6]
In 2014, the trail was significantly extended, with a segment opening between Munster and Hammond.[8] The segment connected a previously existing portion of the Monon Trail located entirely within Munster. The extension required the reconstruction of the old 1909 railroad bridge across the Little Calumet River, at a cost of approximately $1.5million.[9]
The Northern Indiana Commuter Transportation District, which operates the South Shorecommuter rail service, is reconstructing a portion of the rail route along the old Monon right-of-way. The West Lake Corridor project is planned to provide service from southern Lake County communities to and from downtown Chicago;[10] it is estimated to be completed in 2025.[11]

The Monon Trail traverses Indianapolis's north side neighborhoods.
Central Indiana's portion of the Monon covers 28.5 miles (45.9km), beginning at 10th Street in Downtown Indianapolis, passing through various neighborhoods and cities, such as Carmel and Westfield before ending in Sheridan at the Hamilton-Boone county line. Plans to create a shared use trail on the former Monon right-of-way date back to the late 1980s.[12]
In the Indianapolis metro area, the Monon Trail is used by more than 1.3million people annually.[13][14] The trail has been cited as having a positive economic impact to neighborhoods adjacent to the trail, including Broad Ripple in Indianapolis and the mixed-use developments of downtown Carmel, which have experienced a large growth in population over the past decade.[15][16][17][18]
Indianapolis segment
Construction of the Indianapolis segment occurred in phases between 1995 and 2004.[19]
Within the city of Indianapolis, the trail passes through a number of neighborhoods, including Martindale's Hillside neighborhood, the Mapleton-Fall Creek, Meridian-Kessler, Broad Ripple, and Nora neighborhoods. Additionally, the Monon connects with a number of other trails, including the Central Canal Towpath along the Indiana Central Canal, the Fall Creek Greenway, and the Pogues Run Trail.[7] In March 2021, a pedestrian bridge was completed that crossed 38th Street, eliminating a dangerous crossing for trail users.[20] There are plans to build another bridge over 86th Street.[21]
Hamilton County segment
The segment of the trail in Carmel stretches 5.2-mile (8.4km) and was opened in 2002.[22] The first phase of the trail cost approximately $5.5 million to create.[23]
The trail was extended into Westfield starting in the fall of 2008, and has since then been extended north over the abandoned Monon right of way into Sheridan, Indiana, for a total of 6.7 miles (10.8km) in Westfield.[24]
In Hamilton County, the trail provides access to several other pedestrian trails, including the Midland Trace Trail, Hagan-Burke Trail, and Little Eagle Creek Trail.
The connection from 191st Street to 216th Street was completed in 2020.[25]
The final segment of the trail in Hamilton County was opened in Sheridan on October 3, 2025.[26]
