Business routes of Interstate 90

Interstate 90 Business may refer to several business routes of the Interstate Highway System that connects Interstate 90 with the central business district of various cities bypassed by I-90. Each business route can be either a business loop or a business spur, depending on whether both ends connect to I-90. The business route in each community is considered a unique route. In many cases, these routes are a former section of a U.S. Route.

Eventually, I-90 replaced US 10 in Idaho. When the I-90 freeway opened in 1991, the US 10 alignment became I-90 Business. The intersection of Bank Street (US 10, I-90) and Seventh Street was the last traffic light located on a coast-to-coast Interstate highway. It was one of the last, if not the last, removed from an primary Interstate highway. It is the only traffic signal in Wallace and was put into flash mode when the new I-90 viaduct opened.47°28′17.8″N 115°55′20.7″W / 47.471611°N 115.922417°W / 47.471611; -115.922417 ^[2]

I-90 Business passes through the Wallace Historic District. In 1979, several blocks of downtown Wallace were listed on the National Register of Historic Places as a historic district.^[3] City leaders organized the effort to recognize the historic district to prevent the Federal Highway Administration (FHWA) and Idaho Department of Transportation (IDOT) from condemning and demolishing the city's core to build an at-grade freeway. The FHWA and IDOT designed and built an elevated viaduct to finish the interstate freeway.
