The DRPA operates four toll bridges between Philadelphia and South Jersey, as well as the PATCO commuter-rail line.
"When I joined the board of commissioners last year, I said I would remain only as long as it took to return the authority to its core mission: providing safe, reliable, customer-friendly transportation to the people of Southeastern Pennsylvania and Southern New Jersey," Corbett said in a statement Wednesday. "I believe the board is reliably committed to that mission, and the time has come for me to leave it in the board's care."
During Corbett's tenure, a previously approved toll hike took effect, the DRPA doled out the last $29 million of its controversial economic-development funds, and several top managers and most of the Pennsylvania board members were replaced with Corbett selections.
The New Jersey state comptroller issued a report criticizing the DRPA for wasting millions of dollars in tollpayers' money through mismanagement and political cronyism, mostly before Corbett arrived.
And an inspector general hired on Corbett's watch issued his first report, chastising the agency for not fully implementing management reforms approved in 2010.
Simon, 59, of Gwynedd Valley, chaired Corbett's transition teams for Pennsylvania's departments of insurance and public welfare. He served in the administration of Gov. Tom Ridge as chief counsel for the Department of Insurance.
As DRPA chairman, he plans to "continue to focus our mission on transportation. We will continue to strengthen management controls and pursue management efficiencies. Most importantly, we will add value on our customers' terms, not our own."
Reilly, 49, of Middletown Township, is a former chairman of the Delaware County Council.
