Union Pacific Missouri River Bridge
Posted January 18, 2011, by Chris G. (cgaul73059 [at] msn [dot] com)

This bridge replaced a 1888 structure that was not strong enough to support heavier trains. American railroads were booming. The Union Pacific museum in the old headquarters building explained how this bridge was built in 1916.

Peak US track mileage was in 1916. To keep traffic interruptions to the absolute minimum this vital link had to stay open during construction.

To accomplish this, temporary wooden piers were built upstream and downstream of the 1888 stone piers. The new trusses were constructed over the Missouri on the upstream piers. When they were completed, the 1888 bridge was moved from the stone piers onto the downstream wood piers using steam driven winches. The winches were rerigged and pulled the new trusses onto the stone piers. The old span was then removed. Traffic was interrupted less than one day. An amazing piece of engineering and construction!
