Corridor H Highway: The Billion Dollar Boondoggle

Saving pristine areas from highway construction was one of the West Virginia Highlands Conservancy’s organizing principles. As the major four-lane highway project known as Corridor H, designed to link I-79 at Weston with I-66 in Virginia, continues construction through the Monongahela and George Washington National Forests, the Highlands Conservancy continues to mobilize and engage its members to advocate for thorough environmental review and compliance, and a route that ensures the least impact on these environmentally sensitive and unique areas of the Highlands.


The West Virginia Highlands Conservancy supports an alternate northern route for the Parsons-to-Davis section of the Corridor H Highway project. The West Virginia Division of Highway’s current preferred route between the towns of Parsons and Davis climbs Backbone Mountain—made of the notoriously unstable Mauch Chunk formation in the Monongahela National Forest—passes adjacent to the National Natural Landmark Big Run Bog and numerous native trout streams before making its way across the historic Blackwater Canyon towards the booming tourist destination of Blackwater Water Falls State Park and the towns of Thomas and Davis.

The northern route goes north of the towns of Thomas and Davis and preserves the unique mountain culture that people from all over come to enjoy.

Take Action

On April 16, 2024, American Rivers—a prominent national environmental advocacy organization—named the Blackwater River as one of the Most Endangered Rivers of 2024. American Rivers cited the threat of the currently State-preferred (but not yet adopted) southern route for Corridor H—that would cross all of the Blackwater’s headwater streams and potentially unearth acid mine drainage—as a major threat to the beloved river.

Take action by sending a letter to the Federal Highway Administration to mandate an alternate northern route.

Sign the citizen led Go North petition to route Corridor H north of the towns of Davis and Thomas and stay away from the Blackwater Canyon, Blackwater State Park, historic coke ovens, and rail trail. Read the long list of supporting comments here.
