The blocking of the Mercier Bridge resulted in sometimes violent confrontations between the Mohawk and non-Indigenous commuters. On August 28, as Mohawk elders, women and children attempted to leave the Bridge following a negotiated deal between the Mohawk and police officials, members of the LaSalle community threw rocks at their vehicles. Mohawk elder Joe Armstrong, 71, was struck in the chest by a large rock, and suffered a fatal heart attack the following day. At the peak of the crisis, the Mercier Bridge and routes 132, 138 and 207 were all blocked, creating substantial disruption to traffic.
