U.S. Route 52 Business was established in 1960, a renumbering of US 52A through downtown Mount Airy, via Main Street, Renfro Street, and Lebanon Street. Between 1963–1967, US 52 Business was split on one-way streets: northbound via Cherry and Renfro Streets, southbound via Main Street. Sometime between 1969–1972, southbound US 52 Business was removed from Main and Cherry Streets, and moved onto an extended Renfro Street.

U.S. Route 52 Spur is an unsigned 2.98-mile (4.80 km) long spur of U.S. Route 52 in Charleston, South Carolina. It extends from U.S. Route 52 (where it is named Meeting Street) to Broad Street along the northeastern side of the peninsula of downtown Charleston. The route provides access for trucks to shipping terminals of the port on the Charleston peninsula: Union Pier and Columbus Street.
The entire route is in the city of Charleston. 1.29 miles (2.08 km) of the route is named Morrison Drive and the remaining 1.69 miles (2.72 km) is named East Bay Street.
One section of the route, Morrison Drive near Jackson Street, will flood regularly during a spring tide. The eastern terminus is near the historic wharves of Charleston, including Adgers Wharf, which is now the site of a playground. It is also adjacent to the old Exchange, or Customs House, of Charleston. The current Customs House that was built around the time of the Civil War is on this route.
The section named Morrison Drive was constructed in the early 1950s. It was named for William McG. Morrison, mayor of Charleston from 1953 to 1954.
When Morrison Drive was constructed, there was still one private terminal operating near the Eastern terminus, the Clydeline Steamship Company. The Clydeline terminal burned down in 1955. In the late 80s, the land of the terminal was rebuilt as Charleston Waterfront Park.
U.S. Highway 52 Alternate (US 52 Alt.) existed in northeastern Iowa in the 1960s. The original pavement on US 52 between Dubuque and Luxemburg was in such poor condition that the Iowa State Highway Commission rerouted the highway along US 20 and Iowa Highway 136 and the alternate route was established along the old route. Once comprehensive repairs were made to the roadway, the mainline designation was restored to the routing.
U.S. Route 52 Business was established in 1960, a renumbering of US 52A through Pilot Mountain, via Main Street. It was decommissioned in 1964 when the Pilot Mountain Parkway was opened, taking US 52 onto a new alignment west of town.
