State field guide
This release covers Detroit, Grand Rapids, Lansing, Flint, and Ann Arbor. Census Vintage 2025 whole-metro estimates establish guide order. South Bend-Mishawaka, IN-MI ranks sixth among metropolitan areas containing Michigan territory, so it falls outside this five-guide set. Metro counts do not measure city population, project demand, site access, or authority over a work area.

A short municipal runway, snow-heavy winters, and occupied research sites make aircraft fit and ground control front-end decisions.

Major airport traffic, working river terminals, and a helicopter-specific city permit put route and ground control on equal footing.

A cargo airport, active plant investment, and industrial redevelopment meet city streets where staging and oversize moves require permits.

Controlled airspace and a snow-heavy climate meet downtown projects where the safety buffer can consume public right-of-way.

Airport cargo infrastructure and mobility plants sit in a region where snow, freezing nights, and public-space permits can control the schedule.
