Advantages: Option D – Tunnel from 24 Avenue North to 10 Avenue South
 Fastest travel time of all three options. Estimated travel time from 10 Avenue South to northern terminus at North Pointe (Country Hills Boulevard): 28-30 minutes
 Does not impact traffic capacity on Centre Street, south of 16 Avenue North, or on Centre City streets
 Reduced risk of service disruptions due to collisions, compared to Option A, B, and C. Eliminates at-grade pedestrian and vehicle crossings
 Minimal environmental impact
 Underground stations provide protection from the elements for waiting customers
 Underground station at 7 Avenue South provides good connection to existing LRT service on 7 Avenue, and future 8 Avenue subway
 Received strong community support during public engagement

Disadvantages: Option D – Tunnel from 24 Avenue North to 10 Avenue South
 Highest construction cost of all three options (approximately $1.3 billion for the segment of the route between 10 Avenue South and 24 Avenue North)
 Station on Centre Street at 9 Avenue North may not be built due to depth (50 metres/13 storeys), and ongoing operating costs to move passengers to/from track level to surface with elevators/escalators
 Station on Centre Street at 16 Avenue North is 35 metres/9 storeys deep, and station on 2 Street at 2 Avenue South is 27 metres/7 storeys deep
 2013 flood has highlighted vulnerability of public and private infrastructure in the Centre City
