WY 336:
"WilRd_W" is CR 84 and is off to the east. "PraDogRd" is CR1209/1211 and is off to the south. "WilRd_E" is CR 84 and is slightly to the north. "CR42" should be at the Y-intersection and is also where CR 161 intersects.
WY 338:
"I-90BL" is slightly to the north. "WY339" is slightly to the north. "X01" is slightly to the south. "X02" is slightly to the northwest. "TerRd" is slightly to the north. "BeaSpurRd" is CR 108. "AshCreRd" is CR 1237. I think "WY/MT" is about as close as we can get; maybe it should be centered on the road.
WY 339:
"I-90" is slightly to the north.
WY 340:
"CR2" is off to the south.
WY 341:
"US14/16" is off to the southeast. "CR271" is off to the northeast. WY 241 actually ends at Arvada city limits, right where the road goes gravel (RaiSt_S?)
