Potomac Creek Bridge
The Potomac Creek Bridge (Potomac Creek Viaduct or Potomac Run Bridge) was first built in 1842 by the Richmond, Fredericksburg and Potomac Railroad across the Potomac Creek in Stafford County, Virginia.
During the Civil War, the bridge offered the only rail access between the Potomac River and the cities of Fredericksburg and Richmond, making it a vital supply line to both the Confederate and Union armies. In the spring of 1862 as Confederate forces retreated to Fredericksburg the bridge was destroyed.
In 1862, the United States Military Railroad was formed under the command of General Herman Haupt. One of the first tasks was to restore the 13-mile stretch of railroad from Aquia Creek to Falmouth that was destroyed by the retreating Confederate Army. In May 1862, Herman Haupt supervised common Union infantrymen from the Army of the Rappahannock in harvesting two billion feet of local lumber to construct the Potomac Creek Bridge, accomplishing this task in just nine working days. President Abraham Lincoln in a visit on May 28, 1862, observed "That man Haupt has built a bridge five hundred feet long and one hundred feet high, across Potomac Creek, on which loaded trains are passing every hour, and upon my word, gentlemen, there is nothing in it but cornstalks and beanpoles." 
The Haupt bridge stood until June 1863. The Union Army built as many as four railroad bridges atop the same abutment over the remaining years of the war. Around 1899, the bridge was replaced and the south abutment and its approaching right-of-way were abandoned.
