Workers building the historic Stone Arch Bridge (photo above from the late 1800s) over the Ausable River in Keeseville had a close call in 1842. The bridge of native stone, believed at the time to be the largest such bridge in the country, was being built to replace the original wooden structure erected in 1805. The men had completed the first course of stone including the keystones and had nearly finished the second course when a violent storm blew in. Just as more then 30 men fled the storm’s heavy rain to a wooden shed on the bank of the river the entire bridge collapsed into the Ausable with a thunderous crash. The tremendous crash was said to have shaken buildings as far away as Port Kent.
Delays in the construction of the bridge caused by the collapse inadvertently caused a more tragic accident that same year. On local militia “muster day,” September 13, 1842, the unfinished bridge caused the Essex County militia to cross a smaller swinging bridge (supported by chains) nearby. The bridge was filled with bystanders as they marched across in lock step. It’s believed the overloaded bridge combined with the stamping feet of the marchers caused the bridge to collapse into the churning river below. Local newspapers reported that nine people were drowned, and four later died of exposure. Two boys, Richard Pope and Richard Peabody, were swept over a nearby dam with their arms around each other and were among those drowned.
A similar accident twice befell the men building what was then longest bridge in the world (3,239 feet) over the St. Lawrence River at Quebec. As one of the enormous spans was being raised from pontoons, it gave way and crashed into the river taking with it fifty men. Observers said the central span, weighing more than 5,000 tons, buckled at the center before it fell. At least five were killed. The accident occurred in 1916, but just nine years before a similar accident on the same bridge killed 70.In the spring of 1931 the Whallonsburg bridge, which carried much of the Albany-Montreal traffic over the Bouquet River in Essex County, collapsed while Robert O’Neil of Willsboro was crossing. O’Neil’s car fell nearly twelve feet but he escaped uninjured. The bridge’s steel trusses slipped from one of its abutments. The next day four boys were sitting on the railing of the wrecked bridge when it gave way and they went into the water. Kenneth McDougall was knocked unconscious from a serious head injury but the others escaped relatively unharmed. The photo at right shows the new abutments, made of rough quartzite from Champlain Stone.The 1842 Chain Bridge Collapse ranks among the deadliest accidents ever in the Adirondack region.
