In an effort to encourage the passage of a bill expanding the use of red-light cameras outside Philadelphia, state safety advocates and legislators held a news conference at the state Capitol building in Harrisburg on Tuesday afternoon.

Introduced by state Sen. Dominic Pileggi, R-9, and state Rep. Paul Costa, D-34, the bill would allow 20 cities, including Philadelphia, with a minimum population of 18,000, including Harrisburg, Erie, Allentown and Reading, to use the cameras, pending approval by the state Transportation Department. Under the bill, the maximum fine is $100. Known as the Pileggi-Costa intersection safety camera expansion bill, it has already been passed by the state Senate and is pending before the state House of Representatives.

Local state representatives did not immediately return calls Tuesday evening.
