Sherbrooke Street (officially in French: rue Sherbrooke) is a major east–west artery and at 31.3 kilometres (19.4 mi) in length, is the second longest street on the Island of Montreal. The street begins in the town of Montreal West and ends on the extreme tip of the island in Pointe-aux-Trembles, intersecting Gouin Boulevard and joining up with Notre-Dame Street. East of Cavendish Boulevard this road is part of Quebec Route 138. A separate street of the same name exists in Lachine; it does not carry the "West" suffix and repeats numbers that are used on the longer Sherbrooke Street.
