Interstate 115 (I-115) is a 1.19-mile-long (1.92 km) interstate in Butte, Montana that connects Interstate 15 and Interstate 90 to Business 15/90 in downtown Butte. It is a short spur that directs motorists into downtown Butte and continues as Iron Street. Unlike Interstate 315 in Great Falls which is signed as Business Loop 15 cosigning with U.S. Route 89, Interstate 115 is actually signed as such. It is co-signed with Business 15/90 eastbound and Interstate 15 and Interstate 90 westbound.
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]
