The Grand Street Bridge, over the east branch of Newtown Creek and a six mile round trip ride from our starting point, was our 13th bridge. It was our first 'swing' - type bridge and the most poorly maintained deck to date.
From the New York City Department of Transportation:
Grand Street is a two-lane local City street in Queens and Kings Counties. Grand Street runs northeast and extends from the Brooklyn Queens Expressway in Brooklyn to Queens Boulevard in Queens. The road is known as Grand Street west of the bridge and Grand Avenue east of the bridge. The bridge is located between Gardner Avenue in Brooklyn and 47th Street in Queens. The Grand Street Bridge is a 69.2m long swing type bridge with a steel truss superstructure. The general appearance of the bridge remains the same as when it was opened in 1903. The bridge provides a channel with a horizontal clearance of 17.7m and a vertical clearance, in the closed position, of 3.0m at MHW and 4.6m at MLW. The bridge structure carries a two-lane two-way vehicular roadway with sidewalks on either side. The roadway width on the bridge is 6.0m and the sidewalks are 1.8m wide. The height restriction is 4.1m. The approach roadways are wider than the bridge roadway. For example, the width of Grand Avenue at the east approach to the bridge (near 47th Street) is 15.11m.
The first bridge on this site, opened in 1875, quickly became dilapidated due to improper maintenance. Its replacement, opened in 1890, was declared by the War Department in 1898 to be "an obstruction to navigation." Following a thorough study, a plan was adopted in 1899 to improve the bridge and its approaches. The current bridge was opened on February 5, 1903 at a cost of $174,937.
