2021 S Proof "Tunnel" American Innovation $1 - Virginia
The American Innovation $1 Coin representing Virginia recognizes the Chesapeake Bay Bridge-Tunnel. Opened in 1964, the Chesapeake Bay Bridge-Tunnel connects Southeastern Virginia to the entire Delmarva Peninsula.
Spanning more than 17 miles, the bridge tunnel complex consists of 12 miles of low-level trestle, two one-mile-long tunnels, two bridges, two miles of causeway, and four man-made islands. The unique structure is considered the world’s largest bridge-tunnel complex and was designated one of seven engineering wonders of the modern world.
