when was the second tacoma narrows bridge built
Tacoma Narrows Bridge By 1990, population growth and development on the Kitsap Peninsula caused traffic on the bridge to exceed its design capacity; as a result, in 1998 Washington voters approved a measure to support building a parallel bridge. After a series of protests and court battles, construction began in 2002 and the new bridge opened to carry eastbound traffic on July 15, 2007, while the 1950 bridge was reconfigured to carry westbound traffic.
Golden Gate Bridge Strauss was chief engineer in charge of overall design and construction of the bridge project.[14] However, because he had little understanding or experience with cable-suspension designs,[22] responsibility for much of the engineering and architecture fell on other experts. Strauss's initial design proposal (two double cantilever spans linked by a central suspension segment) was unacceptable from a visual standpoint. The final graceful suspension design was conceived and championed by Leon Moisseiff, the engineer of the Manhattan Bridge in New York City.[23]
