On September 24, 2015, five people were killed and fifty were injured when an amphibious "duck tour" vehicle crashed into a charter bus on the bridge in a collision that also involved two smaller vehicles. According to a representative from the Chinese consulate, all of the students were foreign-born. The students all attended North Seattle College, and were on their way to Safeco Field for new student orientation. One witness reported that it appeared as though the duck boat veered into the oncoming bus, after crossing the center line. Some blame for the collision was placed on the narrowness of the bridge deck, which has lanes, and the lack of a median barrier to separate the two directions of traffic. There have also been some calls to reduce the number of lanes from six narrow lanes to four wider lanes, although early reports indicated that a mechanical failure of the duck tour vehicles' front axle may have also been a major factor in the crash.
