[edit] Route description
Interstate 115 begins at an interchange with Interstate 15 / Interstate 90. As a two-lane highway in both directions, I-115 heads east into downtown Butte. Before reaching exit 1, eastbound traffic makes a curve while westbound traffic goes to Interstate 15/90 without making such a curve, therefore that portion of I-115 contains a large median. Approximately 1 mile (1.6 km) from I-15/I-90, I-115 has its only interchange at Excelsior Avenue, which can be used to access the town of Walkerville. Excelsior Avenue is the only numbered exit along I-115, and the structure of the interchange directs motorists to stop and yield signs, as opposed to traffic signals for most exits in urban areas. I-115 ends at the overpass over Excelsior Avenue. It continues into Butte as I-15 Bus. / I-90 Bus..[2]
