How Washtenaw County Moves: Highways, Commutes & Freight

A driver's-eye reference to the interstates, US highways, commute corridors, and freight infrastructure that define how Ann Arbor gets where it's going.

Major Highways in Washtenaw County

Washtenaw County sits at the convergence of I-94, US-23, M-14, and west. Together these routes carry essentially every commercial truck, commuter car, and out-of-state visitor that touches Ann Arbor in a given day — which is why a single closure or rolling backup on any one of them ripples across the rest within minutes.

• I-94
  east-west, primary corridor to Detroit (45 mi east) and Chicago.
• US-23
  north-south, primary corridor to Flint (north) and Toledo/Ohio (south).
• M-14
  northwest connection toward Plymouth and Detroit metro north.
• west
  I-96 accessible via M-14 connection toward Lansing.

Freight, Inland Port & Airport Traffic

Add Detroit Metropolitan Wayne County Airport (DTW) (DTW) to the picture. It is the region's primary commercial airport, and the drive in from Ann Arbor is a short hop.

All figures sourced from state DOT traffic counts, the state Department of Public Safety fact book, the regional ports authority, and the local airport district — refreshed as new annual reports drop. Live conditions, accidents, and lane closures are above; this section explains the system those incidents move through.
