The lower 17 miles (27 km) of the 90-mile-long (140 km) Passaic River downstream of the Dundee Dam is tidally influenced and channelized.[4] Once one of the most heavily used waterways in the Port of New York and New Jersey, it remains partially navigable for commercial marine traffic. While requests have significantly diminished since the mid-late 20th century, the bridge at MP 11.7 and those downstream from it are required by federal regulations to open. Both bridges along New Jersey Route 7 are operated by the NJDOT. The crossing of the Hackensack River, the Wittpenn Bridge, is staffed and opens on demand.[5] The Rutgers Street Bridge requires four hours' notice for opening.[6][7]
As of July 4, 2013, the bridge was formally designated the Lance Corporal Osbrany Montes de Oca Memorial Bridge to honor a North Arlington resident, a 20-year-old U.S. Marine fatally wounded February 10, 2012, while serving in Afghanistan.[13][14][15][16]
