It is named in honour of former member for the Hull electoral district, Alexandre Taché,[1] who served for 15 years with the Union Nationale when the political party was in power under the leadership of Maurice Duplessis.
The road starts at the western limits of the Hull sector with Aylmer just west of Boulevard Saint-Raymond south of the Manoir des Trembles community.
(West of that point, the roadway is known as Chemin d'Aylmer) It travels eastward through the neighbourhoods of Val-Tétrault and Saint-Jean-Bosco while it passes by the southern edge of Gatineau Park, where its parkway begins.
It is a very important route for commuters during rush hours, which frequently causes congestion, especially on the one-lane westbound section between the Université du Québec en Outaouais and Boulevard Saint-Joseph during the afternoon and near the Chaudière Bridge in the morning, as only one lane is available for regular vehicles eastbound.
The section between Boulevard Saint-Joseph and Rue Montcalm contains a feature similar to the Champlain Bridge, where the center lane (which is usually for westbound traffic) is available for buses and taxicabs heading eastbound during the morning commute.
