Where we work across Metro Detroit

How the map is cut

Metro Detroit freight is organised by county, so this section is too. Wayne County had 1,793,561 people at the 2020 census and holds the Rouge complex, Detroit Metropolitan Airport and the river terminals. Oakland County had 1,274,395 and holds supplier headquarters and tech centres. Macomb County had 881,217 and took 65 percent of Michigan federal defense contract dollars in 2024. Detroit itself had 639,111.

Outside the three counties

Four cities sit beyond them. Ann Arbor and Ypsilanti are in Washtenaw County, whose seat is Ann Arbor and which has a university, automotive research and a vehicle emissions laboratory. Monroe is the seat of Monroe County and has Michigan's only Lake Erie port. Port Huron is the seat of St. Clair County, where the Blue Water Bridge to Ontario stands.

How to use this section

Find the place nearest your dock, then write the request with the footprint, height, wall count and bottom. If your town is not listed, the nearest county still applies, and a ZIP code is enough to work from.

Which freeways enter which county

Sources: Wikipedia, Interstate 75 in Michigan, retrieved 12 November 2026; Wikipedia, Interstate 94 in Michigan, retrieved 12 November 2026; Wikipedia, Interstate 96, retrieved 12 November 2026; Wikipedia, Interstate 696, retrieved 12 November 2026. I-696 runs from the I-96, I-275 and M-5 interchange at the Novi and Farmington Hills border to I-94 in St. Clair Shores, and meets I-75 at a four-level stack near Royal Oak and Madison Heights. A seller on one county line should read the county page it sits in; a freeway name alone does not say which county a building is in.

Three freight anchors

The Port of Detroit is the largest inland port in Michigan (Wikipedia, Port of Detroit, retrieved 12 November 2026). Detroit Metropolitan Airport at Romulus covers 4,850 acres with six concrete runways and listed 354,581,419 lb of cargo in its 2025 statistics (Wikipedia, Detroit Metropolitan Airport, retrieved 12 November 2026). The Ambassador Bridge counts more than 10,000 trucks a day (Wikipedia, Ambassador Bridge, retrieved 12 November 2026). The three sit in or beside Wayne County, which is why the Wayne County page carries the most freight context.
