Norwegian County Road 255

County Road 255 (Fylkesvei 255) is a 108.4 km road in Innlandet County, Norway. It runs from Vinstra in the municipality of Nord-Fron to Lillehammer.

The road is being improved (it is being widened and a pedestrian path and bicycle path are being added) between Hovemoen and Segalstad bru and a connection is being built from Hovemoen to Storhove.

Before January 1, 2010 the route was a national road. It was reclassified as a county road in line with a reform transferring such routes to the counties.
