Crews with the Arkansas Missouri Railroad started work on Monday on the railroad trestle under Gregg Avenue by Gordon Long Park in Fayetteville.
And that means a portion of Scull Creek Trail will be temporarily closed.
The city suggests trail users take a detour on the east side of Gregg, but to use caution while crossing the street, since there's no crosswalk.
The work is expected to wrap up Tuesday evening.
