PRELIMINARY DESIGN - LIGHT-RAIL SYSTEM (LRS) – HIGHWAY 10 / DOWNTOWN MONTREAL AXIS

The governments of Quebec and Canada commissioned the MTA  to develop the preliminary plans and estimates necessary for international invitations to tender for the project’s implementation as  a "turn-key" project and its possible operation for the implementation of a light rail system (LRS) at the Highway 10/ Downtown Montreal axis. This system would connect the special Brossard-Chevrier parking to Central Station in downtown Montreal, an approximate distance of 14 km, comprising 5 stations and a control center-garage-workshops complex.
