Oregon Route 501 (OR 501) is an Oregon state highway running from the town of Alsea south 9.49 miles where it ends and turns into Lobster Valley Road at the intersection of Hazel Glen Road near the Benton-Lane County line.

OR 501 begins at the intersection of OR 34 in the small rural town of Alsea, from there, it heads south through mostly forested, rural land, following the route of the original logging roads making it extremely curvy at its southern end where it ends and turns into county maintained Lobster Valley Road.

[citation needed] The original route of OR 501 was to connect OR 34 in Alsea to OR 36 in Deadwood, hence the name "Alsea-Deadwood Highway".

Thus, leaving the current 9.49 miles from the small community of Alsea going south as the only section still part of the Oregon state highway system, still maintained by ODOT currentley.

Because of the low traffic volume on the Highway, ODOT has never attempted to straighten, widen or upgrade it, they have also never completely resurfaced it causing it to fall somewhat in disrepair over the years.
