Restricted Airspace

• Port Huron is near Class D airspace centered on St. Clair County International Airport (PHN), located approximately 6 NM southwest of downtown. The Class D surface area extends approximately 4.5 NM radius from PHN up to 3,000 feet AGL. Most of downtown Port Huron is outside the Class D surface area, but operators in the southwestern part of the city should check the FAA B4UFLY app for specific boundaries. The proximity to Detroit Metro Class B airspace (DTW) approximately 50 NM south affects high-altitude transit corridors.
• The Blue Water Bridge is a major international border crossing and critical infrastructure consideration. The bridge connects Port Huron to Point Edward, Ontario, Canada, and is one of the busiest commercial border crossings between the US and Canada. The $239 million Blue Water Bridge plaza expansion project is a major construction project. Operations near the bridge and the land port of entry have enhanced security considerations from U.S. Customs and Border Protection (CBP) and the Canada Border Services Agency. Drone flights near the bridge and border crossing are restricted and require coordination with CBP.
• The St. Clair River corridor is an international waterway with Coast Guard and border security considerations. The river forms the US-Canada border and has active commercial shipping traffic. Operations near the river corridor should coordinate with the U.S. Coast Guard Sector Detroit. The Black River and the Port Huron harbor have recreational and environmental considerations. The Fort Gratiot Lighthouse and the Lake Huron shoreline have tourism and environmental monitoring demand.
• The I-94 and I-69 highway corridors are major infrastructure assets. MDOT Bay Region manages state highway infrastructure in the area. The $239 million Blue Water Bridge plaza expansion includes highway interchange reconstruction and commercial vehicle inspection facility construction. The Pine Grove Avenue and Military Street corridors have ongoing commercial development. The St. Clair County Road Commission has an active construction and infrastructure inspection program.
• Port Huron is home to the McLaren Port Huron hospital campus, the St. Clair County Community College campus, and the downtown commercial district. The hospital campus has medical facility and privacy considerations. The SC4 campus includes academic buildings and residential facilities. The downtown Huron Avenue commercial district has dense retail and residential development. Operations near the campus and downtown area should coordinate with facility management and the Port Huron Downtown Development Authority.
