GEORGETOWN, Colo. (AP) – Most people know it as the eastbound bore of the Eisenhower Tunnel on Interstate 70.
But its official name is the Edwin C. Johnson Tunnel, and it turned 30 years old Monday.
The 1.7-mile-long tunnel at 11,112 feet opened to I-70 traffic on Dec. 21, 1979.
The tunnel takes travelers under the Continental Divide, letting them bypass a 9.5-mile drive on U.S. 6 over Loveland Pass.
Before the Johnson Tunnel opened, a single lane of traffic in each direction went through the Eisenhower bore. In 30 years, more than 125 million vehicles have traveled through the Johnson Tunnel.
It is named for Edwin C. Johnson, a former Colorado governor, lieutenant governor, state legislator and U.S. senator.
