The Big Walker Mountain Tunnel is a vehicular tunnel in the Appalachian Mountains of Southwest Virginia that carries Interstate 77 through and under Big Walker Mountain. It is located a few miles south of the town of Bland in Bland County and a segment of the Appalachian Trail, and about 20 miles (32 km) south of its longer cousin, the East River Mountain Tunnel.

The 4,229-foot (1,289 m) tunnel was first opened in 1972 after five years of construction labor. It carried a price tag of $50 million (equivalent to $276 million in 2023[1]), which at the time was the most expensive single project undertaken on Virginia's Interstate system.[2] The opening of the tunnel reduced the travel time from Wytheville to Bland County by 30 minutes.[3]
Preliminary engineering studies for the project were made by Brokenborough & Watkins, consulting engineers of Richmond, Virginia, and the final design of the roadway and tunnel was by Singstad & Kehart, consulting engineers of New York City.
The north tunnel approach and surrounding area can be viewed from the Big Walker Lookout, a 100-foot (30 m) observation tower built on Big Walker Mountain about five miles (8.0 km) west of the tunnel.
