The North Shore riverfront trail has been closed at the construction site of the $450 million Majestic Star casino.

Bob Oltmanns, a spokesman for casino owner Don Barden, said the trail would reopen and there would be full access to it once the casino opens in 2009.

City transportation planner Sidney Kaikai said he is working with Bike Pittsburgh and Friends of the Riverfront to try to devise a safe detour for trail users around the casino site during construction.
