  1. Slide-in of I-75 Bridge over US-6 Tim Keller, PE, Ohio DOT Bob Beasley, PE, ARCADIS US, Inc.

  2. AGENDA • Tim • Accelerated Bridge Construction (ABC) in Ohio • Bob • Project Description • ABC Approach for I-75 over US-6 • Bridge and ABC Details • Construction

  3. Accelerated Bridge Construction in Ohio • ABC is not a new concept in Ohio. • How long will it take to build this bridge? • How much disruption to traffic? • Years, Months, Weeks, Days

  4. Accelerated Bridge Construction in Ohio • Why Slide-in construction? • NOT New. • Why Pilot Program? • Why I-75 over US-6? • Public Outreach

  5. Project Description • Location • Timeline • Structure Type • Project Changes

  6. Location Insert Location Map

  7. Timeline • Programmatic Selection - September 2011 • Structure Type Study Approved – November 2012 • Use Accelerated Bridge Construction – December 2012 • Incorporate Project into 3rd Land Widening Project – February 2013 • Revised Structure Type Study Approved – March 2013 • Final Plan Package Submitted – December 2013 • Project Awarded – May 2014 • Bridge Slide – June 2015

  8. Structure Type • Existing Twin Structures: • 4-Span Rolled Steel Beam & Concrete Deck • Spill-through Stub Abutment on H-piles • Cap & Column Piers on Spread Footings • Proposed Structures: • 2-99’ Span Prestressed Concrete I-beam & Concrete Deck • Widen Roadway from 41’-4” to 60’-0” • Stub Abutment on H-piles behind MSE Wall • Cap & Column Pier on H-piles

  9. Project Changes • Profile Adjustment to Facilitate Bridge Slide • Revise I-75 profile to match existing • Lower US-6 profile to provide vertical clearance • Maintenance of Traffic for Bridge Closure • Contraflow and use of ramp

  10. ABC Approach for I-75 over US-6 • ABC Homework • Attend FHWA ABC Workshops • General Approach to Slide-in

  11. ABC Homework • How to slide: • Push, pull • Sliding surface – PTFE, rollers, etc. • Similar projects: • Iowa’s DOT SR 92 over small stream • 120’ Single Span Precast I-Beams • Slid on PTFE coated elastomeric bearings • Utah DOT I-80 over Echo Dam road • 78’ Single Span Precast I-Beams • Slid on PTFE coated elastomeric bearings • Superstructure supported on temporary steel bents • Approach Slabs moved with superstructure • FHWA: • Website • Webinars • Workshops

  12. Attend FHWA ABC Workshops • Utah: I-84 over Echo Frontage Road • Single span precast box beams & no approach slab • August, 2013 • Bridge Slide • Pulled using 2 cranes with cable placed through diaphragm • Slid on PTFE coated elastomeric bearings

  13. Attend FHWA ABC Workshops • Utah: I-84 over Echo Frontage Road

  14. Attend FHWA ABC Workshops • Utah: I-84 over Echo Frontage Road • Lessons Learned • Pulling with cranes • Tension in cable difficult to control • Sliding force is variable at each end • Bridge tended to “rack” • Sliding on PTFE coated elastomeric bearings • Bearings are very “slippery” • Did not take much force to move bridge • Kinetic friction much less than static friction • “Racking” of bridge difficult to control

  15. Attend FHWA ABC Workshops • New York: I-84 over Dingle Ridge Road • Single span precast double tee NEXT beams & precast approach slab • October, 2013 • Bridge Slide • Pushed with hydraulic ram on steel guide rail • Slid on PTFE coated elastomeric bearings

  16. Attend FHWA ABC Workshops • New York: I-84 over Dingle Ridge Road

  17. Attend FHWA ABC Workshops • New York: I-84 over Dingle Ridge Road • Lesson Learned • Sliding on PTFE coated elastomeric bearings • Rain during move increases coefficient of friction • Measure movements during slide to control racking • Pushing with hydraulic ram effective way to slide • Construction of temporary supports most time consuming portion of building bridge

  28. Bridge and ABC Details • Abutment & Approach Slab • Pier • Superstructure & Approach Slab • Slide-in Restrictions/Liberties

  29. Abutment & Approach Slab Before Closure

  30. Abutment & Approach Slab During Closure

  31. Pier • Proposed pier in same location as existing • Temporary support required • Load rating of existing beams with new span arrangement • Seismic pedestal • Pedestal conflicts with bridge slide • Cheekwall designed as seismic pedestal

  38. Slide-in Restrictions/Liberties • How to move bridge • Slide Only

  39. Slide-in Restrictions/Liberties • Temporary supports

  40. Slide-in Restrictions/Liberties • Geometry Control • Limit translation: • 1” between supports • 2” between abutments

  41. Slide-in Restrictions/Liberties • Test Move

  42. Slide-in Restrictions/Liberties • Schedule

  43. Construction • I-75 3rd Lane Widening - $71,178,816 • I-75 Bridges over US-6: $7,790,879 (includes MSE Walls) • Slide Cost: $2,000,000 (25.7%) • Temporary Support of Existing Bridge: $450,000 (5.8%) • 3rd Lane Project Schedule • Summer 2014 to Summer 2016 • Slide-in Schedule • Early Summer 2015
