Context paragraphs:
Jay Street Bridge: The Jay Street Bridge crosses the West Branch Susquehanna River between Lock Haven on the south bank and Lockport on the north.  The original structure, completed for the Lock Haven Bridge Company by the E. Kirkbride Company in 1852, was a covered bridge about 800 ft long.  A two-story toll house, 48 ft long and 18 ft wide was later added at the foot of the bridge on the Lock Haven side.  Travelers using the bridge passed through an archway in the center of the toll house.  The bridge included a covered pedestrian walkway on the downstream side.

Putnam Street Bridge: The Putnam Street Bridge, also known as the Marietta Bridge, is a historical United States river crossing that connects Marietta, Ohio with its Fort Harmar district.

Madison Street Bridge (Portland, Oregon): The Madison Street Bridge, or Madison Bridge, refers to two different bridges that spanned the Willamette River in Portland, Oregon, from 1891 to 1900 and from 1900 to 1909.  The bridges connected Madison Street, on the river's west bank, and Hawthorne Avenue, on the east bank, on approximately the same alignment as the existing Hawthorne Bridge.  The original and later bridges are sometimes referred to as Madison Street Bridge No. 1 and Madison Street Bridge No. 2, respectively.  The second bridge, built in 1900, has alternatively been referred to as the "rebuilt" Madison Street Bridge (of 1891), rather than as a new bridge, because it was rebuilt on the same piers. Both were swing bridges, whereas their successor, the Hawthorne Bridge, is a vertical-lift-type.

Center Street Bridge: The Center Street Bridge is an automobile bridge located in Salem, Oregon, United States.  It spans the Willamette River, connecting West Salem and Oregon Route 22 to Salem.  It carries vehicle traffic eastbound from Route 22 and directly from Wallace Road.  Traffic exits onto Center Street directly, and onto Front Street via an off-ramp, which was built in 1977.  Construction of the bridge started in 1917.  The bridge was officially opened on July 30, 1918, to two-way vehicle traffic.  It was later switched to eastbound-only when the westbound-only Marion Street Bridge opened in 1954.  Center Street Bridge replaced the steel bridge that had been built in 1891, and was reconstructed in 1983 after the completion of a widening project from two to four lanes on the Marion Street Bridge.

Marion Street Bridge: The Marion Street Bridge is an automobile bridge located in Salem, Oregon, United States.  It spans the Willamette River to connect Salem and West Salem, and acts as a conduit for Oregon Route 22.  The bridge carries vehicular traffic one way westbound.  Traffic includes two lanes that flow onto the bridge from Marion Street, vehicles turning right from Commercial Street, and traffic from a quarter-loop on-ramp from Front Street that was added in 1981.  Construction began in December 1952 and the bridge opened in 1954, after taking nearly three years to complete.  The bridge was built to complement the Center Street Bridge, which switched from two-way traffic to eastbound-only, later expanding to four lanes in 1982.  At the time of its opening, the Marion Street Bridge was the longest bridge of its type west of the Mississippi River.

Grand Street Bridge (Connecticut): The Grand Street Bridge was a double-leaf deck-girder bascule bridge in Bridgeport, Connecticut, United States, that spanned the Pequonnock River and connected Grand Street and Artic Street.  It was one of three movable bridges planned by the City of Bridgeport in 1916 at the request of the War Department during World War I.  Construction was completed in 1919, but the delays surrounding the construction went to the Connecticut Supreme Court in case of "Edward DeV.  Tompkins, Inc. vs. City of Bridgeport, Connecticut".  The court ruled in favor of Tompkins and awarded damages equal to the contract.  In 1936, the bridge had excessive settling and required the replacement of its southeast pier.  As part of the repairs, a new floor and electrical system were installed.  In 1965, the floor was replaced with a steel grate on I-beam floor.  In 1984, the eastern approach span was replaced and the northwest trunnion post was reconstructed.  The bridge was closed in the 1990s and dismantled in 1999.

John Basilone Veterans Memorial Bridge: The John Basilone Veterans Memorial Bridge is a bridge in New Jersey that crosses the Raritan River.

The bridge connects First Avenue and what used to be the short one way block of Lyman Street in Raritan with River Road in Hillsborough.  After crossing into Hillsborough, the road curves to meet up with the old alignment with the Nevius Street Bridge.  The bridge is named for local World War II hero, John Basilone.  The bridge has a pedestrian tunnel underneath its northern approach, as part of the Raritan River Greenway.

Newtown Creek: Newtown Creek, a 3.5 mi long tributary of the East River, is an estuary that forms part of the border between the boroughs of Brooklyn and Queens, in New York City.  Channelization made it one of the most heavily used bodies of water in the Port of New York and New Jersey and thus one of the most polluted industrial sites in the US, containing years of discarded toxins, an estimated 30000000 USgal of spilled oil, including the Greenpoint oil spill, raw sewage from New York City’s sewer system, and other accumulation from a total of 1,491 sites.
