The construction of the Wellington Tunnel is associated with Camilien Houde and his political program implemented following the 1929 economic crisis to combat the Depression and unemployment.

Abandoned for over 20 years, the Wellington Tunnel is a reminder of the time when Griffintown was bustling with life, before the rezoning of the 1970s and 1980s. It is part of the area around the Wellington/Murray intersection, which also includes the remains of St. Ann’s Church, the public urinals, and what was once the row of houses on de la Montagne Street. With its four lanes (pedestrian, streetcar, and two lanes for cars), it is part of the evolving transportation network of Montreal, especially in the southwest.

Today, the tunnel’s northern entrance is blocked by concrete blocks and iron bars. Meanwhile, the southern end at the Lachine Canal has been buried. In recent years, this part of the city has been under significant real estate development pressure.
