A Bertha Sized Update
Presented by Taylor Hodges (Alaskan Way Viaduct Consultant)
The Alaskan Way Viaduct, an elevated section of State Route 99 in Seattle, was built in the 1950s, and decades of daily wear and tear have taken their toll on the structure. Because of the viaduct’s age and vulnerability to earthquakes, replacing it is critical to public safety.
Major elements of the program include:
- A two-mile-long tunnel beneath downtown Seattle.
- A mile-long stretch of new highway that connects to the south entrance of the tunnel, near Seattle’s stadiums.
- A new overpass at the south end of downtown that allows traffic to bypass train blockages near Seattle’s busiest port terminal.
- Demolition of the viaduct’s downtown waterfront section.
- A new Alaskan Way surface street along the waterfront that connects SR 99 to downtown.
Location: Building 3, room 102
Students wishing to register for Science Seminar may take it for credit as Ge Sc 190/1 (items 6080 and 6082 respectively).
Science Seminar is a weekly set of presentations by Highline faculty about an area in their field of expertise. Designed to illustrate the cutting edge of science, technology and medicine for a general audience, the series is open to the public but also can be taken for college credit. In some cases faculty from outside the sciences illustrate how science and technology impact their field.
