Fact check: What was the total construction cost of Alligator Alley in Florida?

Checked on July 17, 2025

1. Summary of the results

Based on the available analyses, the total original construction cost of Alligator Alley in Florida is not provided in any of the sources examined. The analyses reveal only information about recent improvement and maintenance projects, not the historical construction costs of the original highway.

The sources contain the following specific cost information:

  • An SR 93 (I-75 Alligator Alley) RRR Improvements Project with an estimated cost of $64.1 million [1]
  • A separate Resurfacing, Restoration, and Rehabilitation (RRR) Project that cost $27,933,983 [2]
  • Wildlife fence extension estimates ranging from $950,000 to $2,698,578 depending on the length of fence installed [3]

2. Missing context/alternative viewpoints

The analyses reveal a significant gap in available information regarding the original construction cost of Alligator Alley. The sources focus exclusively on modern improvement and maintenance projects rather than the historical construction data from when the highway was originally built.

Key missing context includes:

  • The original construction timeline and costs from when Alligator Alley was first built
  • Inflation-adjusted comparisons between original costs and current improvement projects
  • Comprehensive project scope - whether the costs mentioned represent partial segments or the entire highway system
  • Different project types - the distinction between new construction, resurfacing, restoration, and wildlife mitigation projects

The Florida Department of Transportation (FDOT) would benefit from having comprehensive historical cost data readily available, as this information supports budget planning and public transparency regarding infrastructure investments.

3. Potential misinformation/bias in the original statement

The original question itself does not contain misinformation or bias - it is a straightforward factual inquiry about construction costs. However, the lack of available data in the sources suggests potential issues with:

  • Information accessibility - critical historical infrastructure cost data may not be readily available to the public
  • Documentation practices - there may be gaps in how historical construction costs were recorded or preserved
  • Source limitations - the analyses may have been drawn from sources focused on current projects rather than historical records

The question assumes that total construction cost data exists and is accessible, which the analyses suggest may not be the case, at least in readily available public sources.
