The St. Louis bridge, a massive structure, was completed in 1874 at a cost of over $10,000,000. It consists of three spans, the center one being 520 feet long, and the other two 500 feet each. The piers upon which these spans rest are built of limestone carried down to bed rock. The main passage for the accommodation of pedestrians is 54 feet wide, and below this are two lines of rails. The merchant's bridge, 3 miles N., was completed in 1890 at a cost of $3,000,000. The latter is used exclusively for railroad traffic.
