The Q54 will be re-routed to by bypass a portion of Metropolitan Ave to stop at Atlas Park. I'm not sure the effective date, but it's soon.
On the map above, the route in red is the new route. The route in blue is the old route.
Don't know how much this affects the car-less in Forest Hills, since most live closer to Austin - which is a hike from Metropolitan when you're carrying bags from Atlas Park. Yes, you can transfer to the Q23, but nobody's going to spend an entire Saturday on buses to go to California Pizza Kitchen. I guess this move is for other neighborhoods (Kew Gardens, etc) which have higher concentrations of residences near Metropolitan.
