As foreshadowed in some discussion in the old CHM forum and over at AARoads, the western bypass of Williston is now complete, and signed as a US route. It's now part of vanilla US 85, rather than Bypass US 85, with mainline US 85 traffic directed onto the new alignment. US 2 has been left alone, with US 85 signage on its route mostly but not completely removed. This avoids the problem with US 17 in Elizabeth City NC, which has business, regular, and bypass US 17s -- in Wiliston, there's business and regular US 2, and a separate regular US 85.
More perplexing is a new eastern bypass signed as "85B" within a US route shield (not with a business, bypass, or other banner). It's not really a business route, but it's not entirely a bypass either since its south end is at ND 1804 and it only connects to US 85 at its north end (where regular US 85 now rejoins US 2 north of town).
More to follow when I settle down for five nights in Regina SK, and can process details and photos I took here in Williston. I still need to travel part of US 2 north of the airport, and most of US 2 business, on my way out of town tomorrow morning.
