Abstract
When the two-lane vehicular tunnel under the Elizabeth River in Virginia was opened to traffic on May 25, 1953, the idea of providing a direct highway link between Norfolk and Portsmouth was brought to fruition. Some of the problems encountered during the construction of the fifth trench-type vehicular underwater crossing to be built in the United States are outlined, and the method of solving these problems is presented. Of particular interest is the method of constructing, floating, and placing the 300-ft, double-shelled, steel casings for the underwater part of the tunnel. It is concluded that the trench-type tunnel was the most economical to build.
