Business Loop I-15 - Dillon

Dillon represents the main service center along the I-15 corridor between Idaho Falls, Idaho and Butte, Montana. A 3.3 mile business loop there joins the city center with Interstate 15 from Exits 62 and 63. The route zigzags through the street grid along a combination of Atlantic, Helena and Montana Streets, which collectively represent old U.S. 91. Business Loop I-15 also provides the connection between Interstate 15 and MT 41 north to Twin Bridges.

The Dillon #Montana Business Loop for I-15 is well signed with a good array of services. #roads
