From Detroit RiverFront Conservancy:
The Dequindre Cut Greenway, an urban recreational path, officially opened to the public in May of 2009. The 1.2-mile greenway, developed through a public, nonprofit and private partnership, offers a pedestrian link between the Riverfront, Eastern Market and many of the residential neighborhoods in between.
Formerly a Grand Truck Railroad line, the Dequindre Cut is a below-street level path that runs parallel to St. Aubin Street, between Mack Avenue and Woodbridge Street just north of the Riverfront. Well-known for its urban artwork and graffiti, the first completed section of the Dequindre Cut is between Woodbridge Street and Gratiot Avenue. The greenway features a 20-foot-wide paved pathway, which includes separate lanes for pedestrian and bicycle traffic. Entrance ramps to the Cut are located at Lafayette Street, Gratiot Avenue and at Woodbridge Street.
The Dequindre Trail Extension, which will connect the first section of the Dequindre Cut from Woodbridge Street south to Atwater Street near Tri-Centennial State Park and the RiverWalk, is under construction and will be completed by the end of 2009. Further north, beginning conceptual plans are underway for phase II of the Dequindre Cut, which would extend the pathway north from Gratiot Avenue to Mack Avenue.
