Detroit Harbor Terminal Building

The Detroit Harbor Terminal Building, also known as the Detroit Marine Terminal Building, was a ten-story warehouse in Detroit, Michigan. The warehouse was located on the Detroit River just downriver from the Ambassador Bridge between S. McKinstry and Clark Streets on West Jefferson Avenue.

On 1 May 1925, the Detroit Railway and Harbor Terminals Company issued $3.75 million in bonds towards the construction of a 12-acre terminal warehouse and related facilities. The large warehouse that would be built was intended to relieve shortage of storage space for the growing city. Construction of a ten-story, 900,000 square feet building, of reinforced concrete, was the largest on the Great Lakes when it opened on 15 March 1926. The new building was designed by Albert Kahn and his firm.

Current status
The former warehouse was acquired by Boblo Island Amusement Co., and used up until 2003 when the site was foreclosed; the Boblo Island Amusement Park had already been long abandoned since 1993. This structure quickly became a hot-spot for explorers, photographers, and vandals; due to the building's immense size, there was plenty of space to partake in these activities.

In 2016, a fire was sparked in the fourth-floor offices of the building, and the blaze was fought throughout the night.

By 2021, the former warehouse was purchased by the Moroun Company, which had plans to demolish it. In 2022, work on the building began but unexpectedly halted. It is suspected that the Detroit-Wayne County Port Authority may have been the reason why the Moroun Company hasn't proceeded with demolition, as the authority stated its objection to the plan. In late March 2023, demolition resumed, with demolition crews demolishing the Jefferson facade and a large portion of the main warehouse. As of September 2023, demolition of the building has finished, and debris is being removed from the site as of November 2023.
