Tacoma Narrows Bridge

Tacoma Narrows Bridge spans the narrow strait in Washington State with two side-by-side suspension structures connecting Tacoma and the Kitsap Peninsula. The newer crossing from 2007 runs parallel to the older 1950 structure, both featuring tall steel towers and draped supporting cables that carry vehicle traffic above the water.

The first crossing collapsed in 1940 just four months after opening when wind pressure caused violent twisting that was captured on film and influenced bridge builders worldwide. The current twin-span arrangement was completed in two phases starting in 1950 and 2007 using aerodynamically corrected elements.

The twin spans now link two counties through a recognizable cable profile that drivers associate with crossing the Narrows waterway each day. Commuters and travelers use the bridge as a familiar gateway between the Olympic Peninsula and the cities to the east.

Tolls apply only eastbound, so the return trip to Tacoma incurs no charge. Strong winds often sweep through the Narrows, so drivers should watch for crosswind advisories especially when traveling in tall vehicles or with trailers.

Footage of the original collapse remains a standard teaching tool in engineering courses worldwide to demonstrate resonance and aerodynamic instability. The older 1950 span now carries only westbound traffic, making the roadway directionally separated across two physically distinct bridges.
