Idaho State Highways 25 and 77

(1/1)

Amaury:
Where exactly do these begin/terminate over at the Interstate 84 junction at Exit 216? Wikipedia's mapping isn't entirely clear on this. Wikipedia shows Idaho State Highway 25's eastern terminus (despite the odd number, but whatever) being between the westbound and eastbound lanes of Interstate 84 at Exit 216 (basically in the median, except it's on the overpass), while Wikipedia shows Idaho State Highway 77's northern terminus being on the north side of the freeway. So, is there a super short concurrency with these or are the maps just not exact? The state highway shields in the area don't clear this up, either.

According to the Milepoint Logs, SH-77 ends at the eastbound onramp and SH-25 begins at the same junction and continues over the freeway. No overlap, though a bit messier than the normal method of beginning/ending at the centerpoint of an interchange.

Amaury:
Thank you!
