History of Conowingo Bridge
  Several incarnations of the Conowingo Bridge crossed the Susquehanna River at the original location of Conowingo, Maryland, about two miles upstream of the Conowingo Dam, which replaced it. The original Conowingo Bridge was a seven-span, 1,334-foot (407 m), covered bridge built between 1818 and 1820 by Louis Wernwag, who also worked on the Rock Run Bridge. (Another source lists 1844.) that bridge was destroyed, in 1846 or 1847, by a flood. A new wooden covered bridge opened in 1859. This crossing was an important link between Maryland and northern states in the 19th century. During the American Civil Was it was guarded on its southern approach and some of the bridge decking removed to prevent surreptitious crossing. On 6 June 1907, "firebugs" set fire to the 1859 bridge using kerosene. About three-quarters of a mile of it buried. The bridge was rebuilt as a steel structure in 1909. In 1911 the state of Maryland bought the bridge and ended the tolls. With the completion of the dam in 1928 both the town and the crossing were relocated due to the rising waters impounded by the dam. The road crosing moved to the top of the dam. The bridge was destroyed be dynamite.

Looking toward the town of Conowingo. Behind the town you can see the new railroad bridge. The railroad needed to move 6 miles of track to higher ground to get above the new lake level. Both the town of Conowingo and the destroyed bridge are now covered by the lake.
