 The four DART routes will interline in the central sections to form two corridors with extremely frequent service.Along this portion of their routes, bus stops will be widely spaced to increase speed, and there will be "express" sections on each route with no stops for over a kilometre.The interlined routes 50/60 will run from Confederation Mall to The Centre via downtown and the University of Saskatchewan, and routes 70/80 will run from The Mall at Lawson Heights to the University Heights Suburban Centre via SIAST Kelsey Campus, downtown and the University.
