2. Presentation Agenda
• SR 520 – focus project

12. Why is the Pontoon Project needed now?
• Constructing and storing pontoons
are key elements in catastrophic
failure planning.
• If the floating bridge failed,
available detour routes would be
overwhelmed with rerouted traffic.
• Recovering the bridge after a
catastrophic failure will require new
pontoons. We estimate it would
take approximately three years to
construct enough pontoons to
restore the SR 520 bridge.

13. Advanced Construction Methods and Engineering
• Support accelerated schedule,
reduce risk, and minimize costs
• Field test for pontoons, i.e.,
form systems, concrete mixes,
full‐scale mockups of pontoon
sections
• Advertise in Summer 2009‐‐
Posted on WSDOT Contract Ad
and Award Web site
• Located in Grays Harbor
16. How are pontoons built?
• Prepare site
– Excavate a basin, drive piles,
pour concrete slab.
– Stabilize sides of basin with
concrete walls; seal off from
open water with a gate.
– Construct support facilities.
• Construct pontoons
– Assemble forms around steel
frame.
– Pour concrete into forms to
create pontoon.
• Launch pontoons
– Fill basin with water.
– Open gate and use tugboat to
tow pontoon to moorage
location.
– Drain basin and repeat process
for other pontoons.

40. 5-mile project area in red
I‐5 Columbia River Crossing
A bridge, transit, and
highway project aimed
at improving travel
efficiency and safety on
Interstate 5
Vancouver WA Portland OR
Columbia River

41. Project Purpose and Need
• Congestion
Travel demand exceeds capacity
• Freight
Mobility through the area is impaired
• Public transit
Service is limited by congestion
• Safety
Crash rates are too high
Draft EIS document
• Bicyclists and pedestrians
Facilities and connections are inadequate
• Earthquake safety
Bridges don’t meet current seismic standards
41
42. Project Elements
• Replacement bridge for Interstate 5
across the Columbia River
• Light rail extension from Expo Center
in north Portland to Clark College in
Vancouver
• Improvements to seven closely‐
spaced highway interchanges
• Wider path for bicyclists and
pedestrians
• Electronic tolling
