A corridor of the future

• Critical link between Canada and Mexico
• Estimated $40 billion in freight crosses the bridge annually
• One-of-a-kind project
Seven closely spaced interchanges

Number of crashes between 2002-20068
High crash locations - Vancouver
• Crashes 3 to 4 times more likely when bridge lift occurs
• 400 crashes/year; expected to increase to 750 by 2030

High crash locations - Portland
Number of crashes between 2002-20069
• Crash rates for 5-mile I-5 Bridge Influence Area twice as high as comparable inner-urban freeways
• Crash frequency highest in locations with non-standard features
Source: CRC Traffic Technical Report, 2011
• $40 billion in freight crosses bridge; $71 billion by 2030
• 8% of traffic was freight in 2005 (11,000 trucks); 11% by 2030
• 75% of freight trucks crossing bridge uses an interchange in project area
• Trucks traveling in project area are more likely to be involved in a crash
Freight impaired by congestion
10
• Existing bus service is subject to congestion
• Local bus service requires a transfer
• Bike and pedestrian path across bridge is substandard
– Path is only 4 feet wide, next to freeway traffic
– Discourages use
Limited travel options
11
• Aging bridges built in 1917 and 1958
• Existing bridges do not meet current seismic safety standards
• Current wooden pilings do not reach solid rock
Earthquake risk
12
Public process to develop solutions
• 2001 – 2002I-5 Transportation and Trade Partnership
• 2005 – 2008 39-member CRC Task Force
• 2008 – today Project Sponsors Council and citizen advisory groups
• More than 29,000 people engaged at over 950 events
13
• Replacement I-5 bridge
• Improvements to
closely-spaced highway
interchanges
• Light rail extension to
Vancouver
• Pedestrian and bicycle
facility improvements
Long-term, comprehensive solution to improve safety and reduce congestion
14
• Get people out of traffic
• Connection to more than 52 miles of rail network in the region
• Encourage up to 6 million transit boardings per year
Increased safety and reduced congestion by extending light rail

Project Status Update
• Researched in-water pile installation and noise reduction techniques
• Objectives:– Evaluated construction noise– Assessed techniques to reduce
effects to fish and wildlife– Evaluated pile installation
methods
• Results:– Affirmed noise and vibration
modeling– Bubble curtains effective– Fewer pile strikes needed
Test pile installation
21
• National Marine Fisheries Service– Received January 2011
– Not likely to adversely effect:salmonsteelheadsturgeoneulachonsea lionkiller whale
Biological Opinion
22
• Result of IRP findings
• 16-members of national and international bridge expertise
• Panel recommended:–Discontinue work on previous
bridge type
–Suggest three bridge types for further considerationAll less costly and less risky
• Governors’ direct project to move forward with deck truss bridge type
Bridge Review Panel
23
• Review by Oregon State Treasurer
• Recommendations:– Bond yields should be based on
low end of toll revenue range
– Bond yields should not assume annual toll rate increases
– Finance plan should employ:Pre-completion tollsUSDOT TIFIA assistance
• Treasurer recommendations have been incorporated into FEIS
State treasurer review
24
• Review period, Sept. 23 – Oct. 24– Issued on behalf of:
Federal Transit Administration, Federal Highway Administration
– Signed by local project partners:Metro, Southwest Washington
Regional Transportation Commission, C-TRAN, Tri-Met
– Record of Decision expected in December
Final Environmental Impact Statement
25
• Record of Decision allows the project to:– Complete design
– Begin property acquisition in 2012
– Break ground in 2013
• Project to start in 2012
• Purpose:– Verify load carrying capacity
of soil– Evaluate constructability
• 2 locations– 1 in WA, 1 in OR
• Noise and vibration monitoring
Drilled Shaft and Driven Pile program
26
• Responsible for:– Advising CRC project director and staff
– Representing stakeholder organizations
– Communicating routinely with constituencies
• Composed of approximately 30 members– 12-15 from each state
– Terms of 1-2 years
• Meet as large group 1-2 times a year– Vancouver and Portland subcommittees will meet
10-12 times a year
