longest unsigned interval between gas stations

[oscar]

While I traveled US 6 westbound a few miles west of the US 50/93 junction in Ely (to the western turnoff to the Ely business district), I didn't venture out enough to spot a similar sign on westbound US 6.  If there was one, it could've had a higher number.  If there wasn't one, that highway would likely win hands down the "unsigned interval" prize (in one direction), at least in the lower 48.

I drove through Ely again today, on my way from Oregon to Colorado.  This time I spotted a "next gas 167 miles" sign on US 6 westbound just west of the turnoff to the Ely business district.

Once I get the photo out of my camera and edit it, I'll post it in the separate "Longest signed interval between gas stations" thread.
