Maryland has tapped Transurban (USA) Operations, Inc., and Macquarie Infrastructure Developments LLC to lead the development phase of its progressive public-private partnership (P3) plan that will add tolled express lanes to sections of the I-495/Capital Beltway and I-270 corridor. It will also entail building a new Potomac River crossing to Virginia.

Pending state approvals and environmental reviews, the team will negotiate a 50-year agreement to design, construct, and operate the improvements in two of metropolitan Washington’s most congested corridors.
