The Pennsylvania Department of Transportation (PennDOT) oversees transportation issues in the Commonwealth of Pennsylvania. The administrator of PennDOT is the Pennsylvania Secretary of Transportation, currently Leslie Richards. Presently, PennDOT supports over 40,500 miles (65,200 km) of state roads and highways, about 25,000 bridges, as well as new roadway construction, the exception being the Pennsylvania Turnpike Commission, although they currently follow PennDOT policies and procedures. In addition, other modes of transportation are supervised or supported by PennDOT. These include aviation, rail traffic, mass transit, intrastate highway shipping traffic, motor vehicle safety & licensing, and driver licensing. PennDOT also supports the Ports of Philadelphia, Pittsburgh, and Erie. The current budget is approximately $3.8 billion in federal and state funds. The state budget is supported by the motor vehicle fuels tax which is dedicated solely to transportation issues.
