To change directions, trolleys had to turn around. At this location, at the back of what had been the parade grounds of the Michigan Military Academy, the Detroit United Railway (DUR) built a “wye.” This Y-shaped track allowed trolley cars to turn to go in the opposite direction along the trolley track that paralleled the Grand Trunk Railroad track. Nestled in the undergrowth here, barely visible, is a trace of the “wye,” a concrete basin where maintenance workers climbed under the trolleys for inspections and repairs. Near the “wye” was a DUR waiting room to shelter patrons.
