The Connecticut River Walk is partially constructed park and bikeway in Springfield, Massachusetts, United States, along the banks of New England's largest river, the Connecticut River. Currently, Springfield's section of this park is 3.7 miles (6 km) long, running from Chicopee, Massachusetts to the South End Bridge in Springfield, Massachusetts. Unusual features of the trail include its path alongside an active train line, making it a "rail-with-trail," and its passing in very close proximity to the Naismith Memorial Basketball Hall of Fame.[1] The longest river in New England, the Connecticut River is the Knowledge Corridor's most prominent natural asset. For centuries it has been a source of regional identity and pride; however, currently most residents are cut off from it by Interstate 91 - a 1960s-era elevated highway, which has become a major inhibitor to Springfield's economic and recreational riverfront growth, especially in recent years.[2]
