Murry Morgan Bridge's Foot Traffic

There have been rumors about the city closing the Murry Morgan Bridge to foot traffic. The bridge has been closed to vehicles, even emergency vehicles, for over a year and now more changes are afoot. Current volume estimations claim the stairs on the bridge are used only 40 times per day (I think that estimate is low). Do you use the bridge to go into downtown Tacoma? How often? How much impact would it cause to close this route?
