Ann Arbor Traffic & Road Conditions

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.

• 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.
