State Route 77 Aravaipa Creek Bridge Replacement Project

The Arizona Department of Transportation begins a construction project this month (April 2014) to replace the Aravaipa Creek Bridge on State Route 77, which is located about 15 miles north of Mammoth (milepost 123-124).

Construction includes removal of the existing structure in two phases and replacing it with a new concrete bridge. In addition, the project includes installing new guardrails and widening SR 77 to align with the new bridge.

What to Expect
  • Construction is anticipated to begin in April 2014 and is expected to take approximately 12 months to complete.
  • Phase I will close the northbound lane on the bridge, and Phase II will close the southbound lane, with each phase to last approximately six months.
  • Temporary traffic signals will be provided at each end of the bridge to facilitate alternating northbound and southbound traffic.
  • One travel lane will remain open at all times during construction.
  • Warning signs and flaggers for traffic will be provided.
  • Property and business access will be maintained during construction.
  • The project is anticipated to be completed in spring 2015.
