Blennerhassett Island Bridge, with a network arch design, carries U.S. Route 50 (Appalachian Development Highway System's Corridor D) over the Ohio River and the historic Blennerhassett Island between Belpre Township, Washington County, Ohio and Washington, West Virginia in the United States. Construction of the bridge was overseen by the Walsh Construction Company of Chicago, and it opened to traffic on June 13, 2008. The completion of the span completed Corridor D between Interstate 275 east of Cincinnati to Interstate 79 at Clarksburg, West Virginia.
