Roads and Freeways in Metropolitan Detroit - Irregularities in The Gridline Alignment - Mutual

Mutual

This section covers irregularities involving areas where an east–west and north–south road would otherwise intersect. All roads involved with a domino effect will be involved in a single summary.

• In eastern Washtenaw County, M-14 runs diagonally. Because of this, it causes other irregularities. From the west, Warren Road falls off the grid to run along the westbound side of the freeway and T's with Curtis Road. Ford and Plymouth roads physically cross each other near M-14. Ford Road also has an indigenous dirt road segment between Dixboro and Earhart Roads.
• 6 Mile/McNichols in Detroit is interrupted between French Road and Outer Drive/Conner Street by Coleman A. Young Airport. East of that, starting at Gunston Street, it meanders to follow the Woodward grid used throughout Detroit and ends at Gratiot Avenue near Schoenherr Street. Because of this, Sauer Street follows the same grid to Waltham Street.
• Orchard Lake Road physically continues as 9 Mile Road at the Grand River Avenue junctions just north of the M-5 freeway where it curves to have an overpass perpendicular to the freeway whose angle causes other irregularities. From the west, 9 Mile physically continues as Folsom Road (along the eastbound side of the freeway) with a slip ramp to the eastbound side (partial interchange at Farmington Road with east exit and east entrance only); and to the South of Orchard Lake has a sign that indicates the direction of 9 Mile. 9 Mile Road also has an indigenous dirt road segment between Grand River and Freedom road (along the westbound side of the freeway).
• At Shiawassee Road, Farmington Road and 10 Mile Road physically end at T-junctions (10 Mile ending at Farmington north of Shiawassee, Farmington ending at Shiawassee; north T to the west, south T to the east). East of Halsted Road, Grand River physically continues as 10 Mile. Halsted has 2 T-junctions at Grand River (north to the west, south to the east) with an overpass of M-5 between the T-junctions. South of the west T junction, Halsted has a slip ramp onto eastbound M-5; also westbound M-5 has an entrance toward northbound Halsted road.
