The construction results in YRT removing its stops on both sides of Ian Macdonald at the Archives site. YRT has set up a temporary stop for buses on the north side of York Boulevard at Ian Macdonald and rerouted its buses to pick up and drop off passengers at that stop.

The construction affects these routes: Viva Orange; Viva Purple; 3 Thornhill — York University; 10 York University — Woodbridge; 20 Jane — Concord.

Southbound buses operate along their regular route to Steeles Avenue West and Founders’ Road, then continue:

eastward along Steeles;
southward along Keele Street; and then
westward along York Boulevard
to the temporary stop at Ian Macdonald Boulevard.

Northbound buses operate along their regular route.
