  1. 2011 Road Design Conference November 2, 2011 Casey Liles CRC Highway Engineering Manager

  2. 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 2

  3. CRC project area 3

  4. CRC project area 4

  5. Seven closely spaced interchanges 0.6 mi 0.5 mi 0.9 mi 0.6 mi 0.8 mi 0.5 mi Standard Spacing: Desirable = 2 Miles Minimum = 1 Mile 5

  6. 75% of southbound traffic to/from 7 interchanges Source: CRC Traffic Technical Report, 2011 6

  7. Vertical constraints

  8. 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 Number of crashes between 2002-2006 8 Source: CRC Traffic Technical Report, 2011

  9. High crash locations - Portland • 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 Number of crashes between 2002-2006 9 Source: CRC Traffic Technical Report, 2011

  10. Freight impaired by congestion • $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 10

  11. Limited travel options • 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 11

  12. Earthquake risk • Aging bridges built in 1917 and 1958 • Existing bridges do not meet current seismic safety standards • Current wooden pilings do not reach solid rock 12

  13. Public process to develop solutions 2001 – 2002 I-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

  14. Long-term, comprehensive solution to improve safety and reduce congestion Replacement I-5 bridge Improvements to closely-spaced highway interchanges Light rail extension to Vancouver Pedestrian and bicycle facility improvements 14

  15. Increased safety and reduced congestion by replacing the I-5 bridge 15

  16. Interchange improvements - WA

  17. Interchange improvements-OR

  18. Roadway improvements

  19. Increased safety and reduced congestion by extending light rail • 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 19

  20. Project Status Update

  21. Test pile installation • 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 21

  22. Biological Opinion • National Marine Fisheries Service • Received January 2011 • Not likely to adversely effect: • salmon • steelhead • sturgeon • eulachon • sea lion • killer whale 22

  23. Bridge Review Panel • 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 consideration • All less costly and less risky • Governors’ direct project to move forward with deck truss bridge type 23

  24. State treasurer review • 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 tolls • USDOT TIFIA assistance • Treasurer recommendations have been incorporated into FEIS 24

  25. Final Environmental Impact Statement • 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 • Record of Decision allows the project to: • Complete design • Begin property acquisition in 2012 • Break ground in 2013 25

  26. Drilled Shaft and Driven Pile program • 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 26

  27. Bi-State Citizen Advisory Committee • 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 27

  28. Project development schedule 28
