The funeral procession for the three city police officers killed on Saturday will start at noon Thursday at the City-County Building on Grant Street and end at the University of Pittsburgh's Petersen Events Center.

There will be a total closure of Grant Street as the three hearses head to the Port Authority's East Busway at Liberty Avenue. The procession will exit the busway at Neville Street in Oakland and proceed along Neville to Fifth Avenue.

The procession will make a right on Fifth Avenue and continue until DeSoto Street, where it will make another right turn. There, the procession will make a left onto Terrace Street and then right onto Sutherland Drive, arriving at the Petersen Events Center.

Diane Richard, Pittsburgh Police spokeswoman, this afternoon said it will most likely be a miles-long procession with anywhere from 15,000 to 20,000 police officers from cities across the United States and Canada in attendance.

There will also be street closures tomorrow as the bodies of the officers are taken to the City-County Building for the public to pay its respects. There will be a total closure of Grant Street from about 1:45 to 2:30 p.m.

Both Grant Street exits from the Parkway East and West will be closed from 2 until 3:30 p.m. At the same time, there will be a closure of Grant Street northbound at the Boulevard of the Allies through Fourth Avenue and southbound from Forbes Avenue to Fourth Avenue.

And for the next 24 hours, Grant Street will open with one lane in each direction. The curb lanes of Grant Street will be signed NO PARKING from the Boulevard of the Allies to Liberty Avenue. This will permit marked police cars to park while police officers pay their respects.

There will be no parking on the Boulevard of the Allies from Grant Street to Commonwealth Place.

There will also be no parking on Second Avenue from Ross Street to the 10th Street Bridge. The same no parking restrictions will be in place on Ross Street from Second Avenue to Sixth Avenue.

A private viewing for law enforcement officials at the City-County Building will be from 3 to 4 p.m. tomorrow, after which members of the public may enter through the night and until 10 a.m. Thursday.
