Virginia's Public-Private Transportation Act (PPTA) started in 1995 to promote private-sector innovation and investment in transportation projects. Virginia has completed three PPTA projects, including Route 288 and the Pocahontas Parkway near Richmond and the Jamestown 2007 improvements near Williamsburg. The state has six projects in development, including the Downtown Tunnel-Midtown Tunnel Project in Hampton Roads, the I-495 Capital Beltway HOT Lanes in Northern Virginia, Route 58 near Hillsville, and the Coalfields Expressway in the Bristol District. Two PPTA proposals are under consideration: Route 460 and the I-95-395 HOT Lanes. The Metrorail extension to Dulles Airport also is being developed as a PPTA project. Construction has begun on the Capital Beltway with $2 billion of project financing leveraged from an initial $409 million public investment. Governor Bob McDonnell has announced plans to establish a separate multimodal PPTA program office at Virginia DOT.
