Mass-Concrete Mix Helps Speed St. Louis Bridge Project

摘要

The new Mississippi River Bridge, running to and through St. Louis, Mo., will provide a landmark structure with a 1,500-ft main span. The $346-million structure (including approaches) will become the third longest cable-stayed bridge in the U.S. when completed in 2014. The design calls for two lanes in each direction of I-70 with the option to re-stripe for three lanes in both directions in the future.
