North Queen Anne Drive Bridge

The North Queen Anne Drive Bridge is a deck arch bridge that spans Seattle's Wolf Creek. The 238 ft (73 m) long steel and concrete structure was built in 1936 to replace the previous wood-constructed crossing. It serves as a connection between the Queen Anne neighborhood and the George Washington Memorial Bridge that carries State Route 99. The arch is unusually high and uses a minimal amount of supporting members. It was designated a city landmark on December 28, 1981, because of its unique engineering style.[1][2]
