This picturesque little viaduct is just about a half mile from Rowlesburg on Salt Lick Road toward Terra Alta on the West End Run of the B&O Railroad.
"Cranberry Grade is located between M&K Junction and Terra Alta, West Virginia, with a maximum ruling grade of 2.84 % against eastbound trains as the Mountain Subdivision climbs Backbone Mountain. At the east end of the M&K yard is the McMillian interlocking where the yard tracks reconnect with the main two tracks through a system of crossovers. The grade begins to steepen a mile east of McMillian as the railroad begins to climb out of the bottom of the Salt Lick Creek valley towards Amblersburg. At Amblersburg the Mountain Subdivision crosses Salt Lick Creek on a single arch stone viaduct where it turns northeast leaving the Salt Lick Valley to follow Spruce Run to Rodemer. Between Amblersburg and Rodemer the line is almost constantly twisting through curves as the Mountain rapidly gains altitude towards the summit at Terra Alta." from http://www.wvrail.railfan.net/cranberry.html
