The West Side Line caused so many accidents between freight trains and other traffic that the nickname "Death Avenue" was given to Tenth and Eleventh Avenues. In 1929 the city, the state, and New York Central agreed on the West Side Improvement Project, a project that eliminated 105 street-level railroad crossings and cost more than US$150 million (about US$ today). A viaduct, the High Line, replaced the street-level tracks and was dedicated on June 29, 1934. The growth of interstate trucking during the 1950s led to a drop in rail traffic throughout the United States, and the viaduct was effectively abandoned in 1980.
