 The bypass was not the first of its kind on a toll road, as the Pennsylvania Turnpike bypassed the Laurel Hill Tunnel in 1964 in similar fashion, and later bypassed two more tunnels with a single stretch of highway in 1968.The final cost for the entire modernization of the West Virginia Turnpike was $683 million, more than $300 million over original estimates.It was also one of the few Interstates that received 90% federal funding and permission to charge a toll, due to extremely high construction costs.
