## Iowa alternate route

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 in 1964, the Iowa State Highway Commission temporarily rerouted US 52. It was rerouted along US 20 and Iowa Highway 136. As a result of this, the alternate route was then established along the old route. Once comprehensive repairs were made to the roadway by 1968, the mainline designation was restored to the routing.
The entire route was in Dubuque County.

## Ironton business loop

U.S. Route 52 Business is a special business route of U.S. Route 52 in Ironton, Ohio. U.S. Route 52 Business exits the mainline route at the village of Coal Grove, just south of Ironton then follows the original pre-1962 routing of U.S. 52 through the central business district of Ironton before rejoining the mainline near Hanging Rock. U.S. 52 mainline was moved to its current alignment in 1962, which is a controlled-access 4-lane highway which bypasses the city itself. The business route was established at that time but was poorly signed for many years until 1999 when an effort to improve signage was completed. Since then it has been sufficiently signed as U.S. Route 52 Business.

One section of the route, Morrison Drive near Jackson Street, will flood regularly during a spring tide.

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 southern terminus, the Clydeline Steamship Company. The Clydeline terminal burned down in 1955. In the late 1980s, the land of the terminal was rebuilt as Waterfront Park.
