* April 23, 1853 – [[Rancocas Creek]], New Jersey: Engineer of the [[Camden & Amboy]]'s 2 p.m. train out of Camden, New Jersey [[Signal passed at danger|missed stop signals]] and ran his train off an open drawspan at Rancocas Creek. There were 27 fatalities.
* June 29, 1864 – [[St-Hilaire train disaster]], Mont-St-Hilaire, Quebec, Canada: A [[Grand Trunk Railway]] passenger train failed to observe a red signal and ran through an open swing bridge over the [[Richelieu River]]. Ninety-nine were killed and 100 were injured.
* November 7, 1916 – [[Summer Street Bridge Disaster]], [[Boston]], Massachusetts: a [[tram|streetcar]] loaded with passengers ran off an open drawbridge into [[Fort Point Channel]] near downtown Boston killing 46 passengers.
* September 15, 1958 – [[Newark Bay, New Jersey rail accident]], [[Elizabethport]], New Jersey: [[Central Railroad of New Jersey]] (CNJ) commuter train #3314 from [[Bay Head (NJT station)|Bay Head Junction]] to [[Central Railroad of New Jersey Terminal|Jersey City]] ran a stop signal and an open derail protecting the Newark Bay 4-span lift bridge, and the train's two diesel locomotives and two of five passenger cars went into Newark Bay through one of the open spans. Four crewmen, including the engineer and fireman, and 44 passengers died by drowning.
* September 22, 1993 – [[Mobile, Alabama]], US: In heavy fog and low visibility, a disoriented [[towboat]] pilot made a wrong turn and entered a non-navigable waterway.  Due to inexperience and improper radar training, the pilot did not realize he was off-course and [[1993 Big Bayou Canot train wreck|struck an unfinished swing bridge over the Big Bayou Canot around 2:45AM]], knocking it out of alignment by approximately three feet (one meter), although his initial supposition in the low visibility was that one of the barges had run aground.  The rails kinked but did not break, so no fault was indicated for approaching trains.  Approximately 8 minutes later, an Amtrak train carrying 220 passengers derailed at the kinked portion of the rails, killing 47 and injuring 103 more.
* November 23, 1996 – Kearny, New Jersey, US: An [[Amtrak]] passenger and mail train derailed while crossing the [[Portal Bridge]] over the [[Hackensack River]], sideswiping another passenger train in the process. Thirty-four people were injured. A broken rail joint on one pair of the bridge's movable rails at each end of the span caused a track misalignment, while still making electrical contact with the landward rails; thus signals were clear, [[derail]]s closed, and a fault indication was not displayed.
