U.S. Highway 61 Business
Location	St. Francisville, Louisiana
Length	1.729 mi[4] (2.783 km)
Existed	c. 1959–c. 2013

U.S. Highway 61 Business (US 61 Bus.) ran 10.73 miles (17.27 km) through St. Francisville, a town in West Feliciana Parish, Louisiana.[5] The route followed a portion of former US 61 that was bypassed by the current alignment around 1959. Like several other special routes in Louisiana, the designation was unofficial, not recognized by AASHTO or printed on the official state highway maps. It was signed along portions of LA 3057 (Commerce Street) and LA 10 (Jackson Road). Signage was removed around 2013 when new highway markers were installed following the widening of mainline US 61 to four lanes and a change in several highway designations in the area.[5]

The entire highway was in St. Francisville, West Feliciana Parish.

U.S. Highway 61 Business
Location	Davenport, Iowa
Length	10.924 mi (17.580 km)
Existed	2010–present

U.S. Route 61 Business was created in 2010 when U.S. Route 61 was rerouted around Davenport on I-280 and I-80. The route begins on the southwestern end of town at the interchange with I-280. From there, it heads towards the Mississippi River along River Drive. For six blocks, US 61 Bus. is overlapped by US 67, which joins from the south at the Centennial Bridge and parts to the north when US 61 Bus. turns off. For the most of the remaining trip through Davenport, the route runs along two one-way streets: Brady Street (northbound) and Harrison Street (southbound). Near 5th Street in downtown Davenport, the Iowa Interstate Railroad crosses over Brady and Harrison streets. The vertical clearance of both bridges is only 11 feet 8 inches (3.56 m), which causes many trucks that attempt to pass beneath the bridge to hit or become stuck. This bridge was a major factor in US 61's realignment. Just south of Kimberly Road, which carries US 6, the southbound lanes of US 61 Bus. turn onto Harrison Street from Welcome Way. North of 53rd Street, the two directions rejoin as one road. The route ends at the I-80 interchange on the northern side of town.[10] The entire route is inventoried as Iowa Highway 461, but it not signed as such.[11]

This low bridge was one of reasons US 61 relocated onto the interstates around Davenport

The entire route is in Davenport, Scott County.

The business route through Maquoketa follows Main Street through the downtown business district, and Iowa Highway 64 along Platt Street. The route is unsigned, aside from a few circle "City Route 61" signs along Main Street.

Although not designated until 1998, Main Street had essentially served as a "Business 61" since at least the mid-1970s, when U.S. 61 was moved to a two-lane bypass around the south and west parts of the city. The bypass was widened to four-lane freeway in the summer of 1996, as part of a massive four-lane project of U.S. 61 between Dubuque and De Witt.

The entire route is in Maquoketa, Jackson County.
