Overview

SR 73 Post office Canyon Project Map

The Arizona Department of Transportation has started a project on State Route 73 near the community of Whiteriver on the Fort Apache Indian Reservation. The work will reconstruct the Post Office Canyon Bridge at mileposts 348-349.

What to expect during construction

The following restrictions are in place through September from 6 a.m to 6 p.m. seven days a week:

  • SR 73 is narrowed to one lane of alternating north- and southbound travel near the Post Office Canyon Bridge (mileposts 348-349).
  • A temporary traffic signal helps drivers travel through the construction area.
  • 12-foot vehicle width restriction in the work zone.
  • Reduced speed limit in the work zone.

ADOT reminds drivers to proceed through the work zone with caution, slow down and watch for construction personnel and equipment. The restrictions are needed so crews can safely demolish, remove and replace the existing bridge deck, reconstruct the roadway approach transitions, replace guardrails and other related work.
