Yesterday evening, I drove NV 427 while keeping an eye out for any mention of the Fernley US 95 Spur, which is included in the highway browser. Not only is 95 Spur completely unsigned, I cannot find any mention of the spur route online or in the NDOT logs, where a US alternate/spur would typically take precedence over a SR. For this reason, I propose that US95SprFer be deleted in favor of NV427 and I-80BLFer.
This would not result in any reductions to mileage in the network, as the route is 100% concurrent with NV 427, which is well-signed, and the semi-signed BL 80.
