Burnside's Bridge
Burnside's Bridge is a three-arched stone masonry structure spanning Antietam Creek near Sharpsburg, Maryland, constructed in 1836 as part of Washington County's road improvement project to facilitate local traffic and commerce.[1][2] It achieved lasting historical significance during the Battle of Antietam on September 17, 1862, when approximately 500 Confederate soldiers under Brig. Gen. David R. Jones defended the high ground overlooking the bridge against repeated assaults by Maj. Gen. Ambrose E. Burnside's Union IX Corps, delaying the Federal advance for about three hours despite the creek's fordability elsewhere.[3][4] This action at the Lower Bridge—later renamed for Burnside—exemplified the tactical challenges of the day's fighting, which remains the bloodiest single engagement in American history with over 22,000 casualties, though the Union's eventual capture of the crossing came too late to envelop Gen. Robert E. Lee's Army of Northern Virginia before its retreat.[5][6] The bridge's defense highlighted Confederate resilience against superior numbers and has sparked debate over Burnside's decision-making, including his reluctance to probe fords more aggressively, contributing to the battle's inconclusive strategic outcome despite providing President Abraham Lincoln the political opening to issue the Emancipation Proclamation.[7] Today, preserved within Antietam National Battlefield, the site serves as a focal point for interpreting the Maryland Campaign's pivotal clash.[3]Physical Description and Engineering
Architectural Features and Design
Burnside's Bridge is a three-arched stone masonry deck arch bridge spanning Antietam Creek near Sharpsburg, Maryland.[3] Designed by master bridge builder John Weaver, it features coursed limestone construction typical of early 19th-century regional engineering, with the arches providing load-bearing support across the creek's varying water levels.[1] The structure's total length measures 107 feet, comprising three main spans of approximately 34 feet each, while the deck width is 12 feet to accommodate wagons and livestock.[8] Masonry walls encase the roadbed, originally topped with wooden coping for parapets.[1] Completed in 1836 at a cost of $2,300, the bridge exemplifies practical vernacular architecture, utilizing locally quarried limestone for durability against the creek's swift currents and seasonal floods.[1] As one of five bridges attributed to Weaver and part of 14 constructed by Washington County between 1822 and the 1860s, its segmental arches reflect standard hydraulic engineering principles of the era, prioritizing stability over ornamentation for rural crossroads.[1] The design's simplicity—lacking decorative elements—facilitated cost-effective spanning of the 80-foot-wide creek channel flanked by steep bluffs, ensuring reliable passage for agricultural traffic.[3]
