Macro Sites

in reference to blog entry: Autoroute System, 1.

macro sections:


1. At rue St. Laurent, riviere St. Pierre flows North-South. Division the the city East-West. Touchs Champs de Mars. Four Braid Bars, river sand and gravel. (surficial geology - Soils of Montreal analysis data)

2. ?m wall between Place d'Armes Station tunnel and Ville-Marie Expressway autoroute 720

3. rue Bleury and rue Viger intersection: sewage system and aquaduct system intersections : meter chamber, access chambre for principal aquaduct, man-hole sump pump.

4. Rue University at Square Victoria metro station tunnel : rivière St. Pierre leaves behind three point bars. (surficial geology - Soils of Montreal analysis data)
Although these change over time - the 1970's map is indicative the river was braided here. Here was a stream braiding off from the riviere St. Pierre, which crossed over the now Square Victoria station, and flowed South. This is the end of the parallel flow of the metro tunnel and the Ville-Marie Expressway.

Metro System

The orange line (2) metro tunnel which runs parallel to the Ville-Marie Expressway was constructed with cut and cover construction technique, 1964. The bedrock was excavated underneath Rue de Vitre (Rue Viger). They used a wooden framework to form a cast in place concrete tunnel. The tunnel was covered and Rue Viger re-opened.

There exists a section "North" of Place-d'Armes where the tunnel and the Ville-Marie expressway are seperated only by a thick concrete wall.

Hydrology System

Before sewage systems are built, rivers are used as a natural force to carry waste away from the city into a larger bodies of water. Riviere St. Pierre flowed into Lachine Canal. Riviere St. Pierre exists directly under my project site, the Ville-Marie Expressway, where now is a 7' (84") in diametre, reinforced concrete, primary aquaduct built in 1972.

The surficial geology data from two maps (1)(2) reveals the flow of the St. Pierre river. It comes down North- South from where Rue St. Laurent is now. This North-South section is what marks West Montreal from East Montreal. Rue St. Laurent, a Montreal taxi driver told me, is the division between West and East.

The river then turns West, where the Champs de Mars metro station is now, and braids into three or four streams, flowing south west along where the Ville-Marie Expressway is now.

It becomes deeper south of where the Place d'Arme metro station is now, and meanders around two point bars of river sand and gravel and boulder clay (boulder clay is glacial stream desposits which forms underneath glaciers and ice-sheets).

Where the Square Victoria metro station is now, Riviere St.Pierre turns and flows South and eventually flows into the Lachine Canal.
