Site Visit (Eisenhower and Twin Tunnels)
A tour of the Eisenhower-Johnson Memorial Tunnels will be offered on Monday, September 21, 2015. The Eisenhower-Johnson Memorial Tunnels are dual-bore, four-lane vehicular tunnels approximately 50 miles (80 km) west of Denver, Colorado. The tunnels carry Interstate 70 under the Continental Divide in the Rocky Mountains. With a maximum elevation of 11,158 feet (3,401 m) above sea level, they are one of the highest vehicular tunnels in the world. Both the Eisenhower and Johnson bores are approximately 1.7 miles (2.74 km) long, making the tunnels the longest mountain tunnels and highest point on the Interstate Highway system. Completed in 1979, the tunnels were one of the last major pieces of the Interstate Highway system to be completed. While at the tunnels, the tour group will be given a history of the construction, a tour of the control and fan rooms and an update on the current installation of the tunnel fire suppression system.
On the bus trip to the tunnels, a “windshield” tour and recent history (2013-2014) of the widening of the Veteran’s Memorial Tunnels (aka, Twin Tunnels) from two lanes in each direction to three lanes will be given. On the return trip to the hotel, we will make a stop at the Colorado School of Mines to tour its Earth Mechanics Institute (EMI).

Keynote Session: Changing the Urban Landscape
Selling urban underground alternatives to owners, politicians and the public can be a challenge. This session will highlight unique uses of underground space and take a candid look at how major tunneling projects can transform the urban environment for the better.
• Transportation Architecture: Selling the Underground Concept – Speaker TBC
• Lessons Learned in Seattle: Sound Transit’s Link Light Rail – Joe Gildner, Sound Transit

Session 2: Urban Transportation Tunnels
Urban settings provide particular challenges for transportation tunnels. The tunneling industry has several examples of how these problems of space and logistics can be overcome.

Session 3: Urban Wastewater Tunnels
As water and wastewater tunnels comprise many of the ongoing urban projects in North America today, what challenges does the industry face and how are they to be overcome?

Sponsored coffee break & exhibition
4:00pm – 5:00pm
Session 4: Question Time Panel Discussion – Fifty Shades of Green
The question before our panel of project owners and agency representatives Is, “Why are tunnels not considered to be a ‘green’ alternative?” The panel of agency representatives and project owners will discuss environmental benefits and the contrasting perception of linear underground storage and “green” infrastructure solutions on the issue of combined sewer overflows (CSOs).
