 According to plans filed by the state with US DOT, the project is scheduled to run from 2009 through 2016, with work starting at the Massachusetts line and moving northward to Manchester.The project is designed with an intermodal transit bent; new or improved park and ride facilities deployed at exits 1, 3 and 5 and a widened median strip that is designed to accommodate a planned commuter rail service between Boston and Manchester.As a way to help defray the costs of the expansion, in early 2010 the NHDOT made a formal request to the Federal Highway Administration to add tolls to I-93 at the Massachusetts-New Hampshire border.
