  • Originally constructed in 1946
  • Multiple widenings
  • Temporary steel shoring in place
  • Cracks present and some cold joint damage
  • Spalled Concrete at various locations
  • Deteriorated Railings
  • Under designed for current load ratings
  • Canal prohibits changing dimensions
  • Concrete in piers, footings and deck tested strong

 

Two Preliminary Issues (with structure)
1. Effects of time (cracks, spalls and guardrail)

- Repair Structure to original design intent

2.Under designed (1950’s loads vs. 2007+)

- Increase Capacity to current loads

Additional Considerations (repair vs replace)
1. Interruption to the traveling public

(Fewer incidents and shorter duration)

2. Cost of rehabilitation versus replacement.

(Substantial cost savings)

3. Cost savings multiplied by number of structures needing upgraded.
4. C.O.P evaluation of latest technology for future structure upgrades and repairs.
Step 1: Repair structure to original design intent.
