The Arizona Department of Transportation, in conjunction with the Federal Highway Administration, is initiating a rehabilitation project on the Interstate 15 Black Rock Road Bridge.

The construction project, which includes both the north- and southbound bridge structures, is located about two miles south of the Arizona-Utah state line (milepost 27) in the far northwestern part of the state. The project boundaries are between mileposts 27 -28. Construction is scheduled to begin in early 2023 and be completed in spring 2023.

The project is needed to increase the lifespan of the bridge over I-15. The work will include:

  • Placing a concrete surface along the entire bridge decks, which is the top portion of a bridge that motorists drive on.
  • Repaving  the approaches to provide a smooth transition to each bridge structure.
  • Removing and replacing the deck joints with new joints.
  • Removing and replacing the guardrails.
  • Other related work.

What to Expect During Construction

During construction, the Black Rock Road Bridge will be reduced to one lane in each direction during most of the construction. Additional traffic restrictions on north- and southbound I-15 will be in effect when work below the bridge takes place.
