PITTSBURGH — The Steelers and the Pirates filed an appeal Thursday with the state Supreme Court over the master plan for a proposed slots casino, saying the planning commission failed to give adequate consideration to traffic concerns.

Meanwhile, Carnegie Science Center, which previously had traffic and lighting concerns, said it reached a tentative agreement with the casino and does not plan to appeal.

The Steelers believe the city's planning commission made significant legal errors in its May 29 approval, Steelers President Art Rooney II said in a statement.

A spokesman for Detroit businessman Don Barden, whose casino plan was selected last year, said they intend to move forward with plans despite the teams' appeals.

A state panel chose Barden's Majestic Star casino over two other applicants for the sole Pittsburgh gambling license. The two losing bidders have appealed to the court as well.
