The city of Pittsburgh will close the section of Rialto Street in Troy Hill that intersects with Route 28, starting Friday and running through a March date that will be dependent on the weather.

Council President Darlene Harris said yesterday the steep street is hazardous during the winter, and previous attempts to temporarily shut it during snowy periods using wooden barriers weren't effective. The city will use concrete barriers to block both ends of the southernmost block of Rialto Friday.

"It's very unfortunate, but we just can't take a chance" on someone moving wooden barriers and sliding into an accident, said Ms. Harris.
