Public-Private Partnerships

In 1995, Virginia enacted the Public Private Transportation Act (PPTA), allowing private firms to propose, both solicited and unsolicited, innovative project delivery solutions that, in addition to the elements of a traditional design-build project, may include financing, operations, and maintenance. Recognizing the public benefit this law enables, Shirley submitted the first unsolicited PPTA project in Northern Virginia, the Route 28 Corridor Improvements Project. Proposed prior to the start of VDOT’s design-build program, Shirley was awarded the $480 million turn-key Project in 2002 after an extensive competitive process that spanned the terrorists’ attacks of September 11, 2001. With private and public funding provided by a combination of Route 28 commercial landowners VDOT, Shirley implemented a design-build approach to complete ten (10) interchanges, over 14 miles of widening from 6 to 8 lanes, and numerous secondary road improvements. In all, over 15 traffic signals were removed to greatly improve safety and traffic operations in the corridor, years earlier than planned.

Following our success on the Route 28 PPTA Project, Shirley submitted a second unsolicited PPTA proposal to Spotsylvania County, VA. While smaller in scale, the Project successfully developed several intersections and secondary road improvements throughout the County under a design-build delivery.

Through our design-build capabilities, reputation, and financial strength, Shirley is constantly developing and analyzing new PPTA opportunities. Please reach out to our Business Development group to discuss creative ways to develop your project.
