Tacoma narrow bridge.
it collapsed due to resonance excited by strong winds.
It crosses the Tacoma Narrows strait which is part of Puget Sound in Washington state.
Tacoma narrow bridge.
Galloping Gertie, officially known as the Tacoma Narrows Bridge, was built using a suspension bridge design, which was innovative at the time. Construction began in 1938, and the bridge was completed in July 1940. Its design featured a narrow roadway and a unique aerodynamic profile, which ultimately contributed to its infamous oscillations. The bridge collapsed just a few months later, on November 7, 1940, due to aeroelastic flutter caused by high winds.
The original Tacoma Narrows Bridge that was opened in 1940 collapsed due to heavy winds. The roadway twisted and vibrated violently under 40-mile-per-hour (64 km/h) winds on the day of the collapse.
Tacoma bridge fell down because it is too narrow compare to its length. So the bridge was unstable and due to strong wind it was collapsed.
A land bridge. An Isthmus.
A Narrow Bridge sign means that the bridge ahead is only wide enough to accommodate two lanes of traffic with very little room [source: A_Narrow_Bridge_sign_means_that_the_bridge_ahead_is_only_wide_enough_to_accommodate_two_lanes_of_traffic_with_very_little_room]
the Narrow Bridge
A narrow strip of land such as this is called an isthmus.
