Some $2.1 billion will be invested in the state's highways and bridges this year, Corbett said, about $600 million more than would have been spent without the transportation bill.
The extra work will lead to about 18,000 new jobs this year, the Governor's Office said.
More than 900 road projects will be started this year, Corbett said.
Among the projects Corbett mentioned Thursday are:
- Rehabilitating the Birmingham Bridge in Pittsburgh.
- Rehabilitating the Spring Garden Street Bridge over the Schuylkill River in Philadelphia.
- Resurfacing the Trexlertown bypass in Lehigh County.
- Resurfacing more than 145 miles of roads in northeastern Pennsylvania Resurfacing and bridge preservation on the Lock Haven Bypass, in Clinton County.
- Resurfacing more than 142 miles of roads in northwestern Pennsylvania.
“PennDOT is looking intently at its own operations and this review has so far resulted in $100 million a year in recurring savings,” Corbett said. “PennDOT looked internally to ensure that each and every available dollar is invested wisely and that fits my goal of delivering core services to Pennsylvania’s taxpayers in the most efficient way possible.”
