First Bridge Across the Missouri River
One of the most impressive of its day, the Union Pacific Railroad Bridge was built at a cost of nearly $2.9 million. The Grenville Dodge design was a half-mile long and featured 11 spans, each 250 feet long and 60 feet above water. Tubular-iron piers were planted in bedrock and supported with concrete and masonry. Severe winds damaged the structure in 1877. The bridge was repaired in 1887 and rebuilt twice, in 1888 and 1916. The completion of this bridge marked the true completion of the Transcontinental Railroad.
