Pennsylvania's Transportation Commission will submit an updated 12-year, $63.2 billion transportation program to federal officials, said Gov. Tom Corbett.
The Federal Highway Administration and Federal Transit Administration will review the plan. The FHA coordinates with the U.S. Environmental Protection Agency to review the plan's conformity with air quality requirements.
The new plan anticipates using the funds to improve roads, bridges, transit systems, airports and railroads, according to Corbett. The amount is up 52% from the $41.6 billion in the last update two years ago.
"Today's action represents a significant step forward to addressing all transportation modes," Corbett said Aug. 14 in Gettysburg.
Act 89, which lawmakers passed and Corbett signed last year, will add $2.3 billion a year in transportation investment by 2017.
Moody's Investors Service rates Pennsylvania's general obligation bonds Aa3. Fitch Ratings and Stabdard & Poor's assign AA ratings.
