 What is now Route 19 was once planned as the Paterson spur of the Garden State Parkway , which was to run through Paterson and <unk> to County Route 504 in Wayne . The planned Paterson spur would become an extension of Route 20 in 1959 . This road , which was to be a six @-@ lane , $ 58 million freeway called the Paterson Peripheral , was to run from Clifton north to the existing Route 20 in downtown Paterson . This road was completed between the Garden State Parkway and Valley Road by 1969 and north to Interstate 80 in 1975 . Upon completion , this road received the Route 20 designation . The extension to Route 20 through Paterson was stopped in 1971 because of the designation of the Great Falls Historic District , a historical district recognizing Paterson ’ s heritage as an industrial center . By the 1990s , this portion of Route 20 was redesignated Route 19 as it did not connect with the mainline of the route . In 1992 , a project to complete the interchange with I @-@ 80 and extend the route to Main Street in downtown Paterson to ease congestion was finished . This interchange received the Prize Bridge Award in the category of Grade Separation from Modern Steel Construction magazine in 1996 .
