February 1929. The Washington Toll Bridge Authority was created in March 1937 to construct and maintain toll bridges throughout the state, beginning with the Tacoma Narrows Bridge from Tacoma to Gig Harbor and the Lake Washington Floating Bridge from Seattle to Mercer Island. The bridge, designed by American suspension bridge engineer Leon Moisseiff, began construction on November 23, 1938, by the Pacific-General-Columbia Company, a partnership between three companies that received a $2.88 million grant from the Public Works Administration and a $3.52 million loan from the Reconstruction Finance Corporation, to be repaid through tolls. The Tacoma Narrows Bridge opened on July 1, 1940, and included ceremonies attended by an estimated 10,000 people, including Governor of Washington Clarence D. Martin. The bridge, christened the name "Galloping Gertie" by its construction workers, cost $6.4 million to build and became the third longest suspension span in the world after its completion. The following day, the art deco MV Kalakala was chosen to make the commemorative final ferry crossing of the Tacoma Narrows. The original toll for the bridge cost 55 cents per car, 15 cents per extra passenger, and 15 cents for pedestrians. The bridge, which was prone to movement during windstorms, collapsed at approximately 11:00 am on November 7, 1940, because of winds in excess of . The only fatality during the collapse was a dog trapped in a car belonging to local reporter Leonard Coatsworth of Tacoma. A second, Tacoma Narrows Bridge was constructed between 1948 and 1951, officially opening to traffic on October 14, 1950. The bridge was designed to let wind pass through the structure with perforated girders and open grating in the deck. Traffic on the four-lane bridge began increasing from 6,000 vehicles in 1960 to nearly 67,000 vehicles by 1990, according to WSDOT AADT data. The increased traffic prompted the Washington State Legislature to approve the construction of a tolled eastbound bridge in 1999, to be finished during the early 2000s. The eastbound bridge was constructed between 2002 and 2007, opening on July 15, 2007, during ceremonies attended by 60,000 people, including Governor Christine Gregoire. The newer eastbound bridge provided the debut for the Good to Go RFID pass from WSDOT, which allows frequent users to bypass the toll booths by way of a prepaid transponder placed on the inside of the windshield and reducing the toll.
