Due to current levels of federal funding the scheme’s projected completion date is from 2036.
The highway in West Virginia is 75% complete or under construction and will increase to 87% by 2018.
Under the Corridor H Authority’s proposals, a P3 will finance the construction on the remaining 13% of unfunded road from Kerens to Virginia. The 75-mile stretch is expected to cost approximately $700m.
In 1964, Congress authorized the Appalachian Corridor System to connect Appalachia to the rest of the world with limited access four-lane highways. In West Virginia, every Corridor but Corridor H is completed.
Stretching 130 miles from I-79 at Weston, West Virginia it runs to the Virginia border where it is designed to travel an additional 13 miles to the I-66/I-81 junction near Front Royal, Virginia.
Morris said: "We strongly believe that Corridor H can benefit from the use of P3, similar to other projects in West Virginia."
Project leaders are expecting to hear back from the government on their request this summer.
