The US 501 realignment in Myrtle Beach is currently estimated to be completed in fall 2026. Horry County’s project page lists “Estimated Completion Fall 2026,” while a March 2026 update said no exact completion date had been announced yet.

What that means

  • The project is already under construction and affecting traffic in downtown Myrtle Beach.
  • Earlier reporting had projected completion by 2026, and the county’s latest posted estimate narrows that to fall 2026.
  • The work is part of the broader US 501 realignment tied to the downtown roadway changes near 7th Avenue North and Oak Street.

Practical takeaway

If you’re planning around it, the safest assumption is that the realignment should open sometime in fall 2026 , but the exact day hasn’t been published yet.
