The Collier Run Culvert (mi. 173.78) is unique because the upstream opening can be seen from Maryland Route 51. Heading from Cumberland, it comes into view just prior to reaching the Spring Gap Drive-in Camp. The stream runs pretty deep both coming into and exiting the culvert, and the structure itself is in excellent condition. I honestly didn’t plan on exploring the C&O Canal today, but coming back from Morgantown, WV, I was getting really tired of the unusually high amount of traffic on I-68. I decided to take the back way into Martinsburg, and I would like to give credit to Candee for spotting this incredible structure as I was flying down the road.
