Best Alternative Routes

Pro Tip: When main arteries are congested, parallel residential streets often provide faster movement, but respect neighborhood speed limits and watch for pedestrians.

North-South Alternatives to US-23

Route Start/End Points Best For Peak Time Savings
Huron Parkway Plymouth Rd to Washtenaw Ave Avoiding US-23 between exits 41-37 10-20 minutes
Dixboro Road Plymouth Rd to Geddes Rd Southbound morning commute 5-15 minutes
Maple Road Jackson Rd to Dexter Ave West side north-south movement 8-12 minutes

East-West Alternatives to Washtenaw Avenue

  • Plymouth Road: Less congested parallel route with multiple lanes
  • Miller Avenue: Connects Maple to downtown with moderate traffic
  • Eisenhower Parkway: Good alternative for Briarwood Mall area
  • Stadium Boulevard: Bypasses downtown but can be busy near Pioneer High School

Downtown Bypass Routes

To avoid downtown congestion completely:

  1. North Side: Huron Street to Broadway to Maiden Lane
  2. South Side: Stadium Boulevard to Main Street to Pauline
  3. Full Bypass: M-14 to Jackson Road to Maple Road (for west side destinations)

Special Event Routing

For University of Michigan football games and large downtown events:

  • Approach from North: Use Barton Drive to Bandemer Park area parking
  • Approach from South: Use State Street or Main Street with early arrival (3+ hours before kickoff)
  • Post-game Exit: Wait 90 minutes after game ends or use side streets like Greene or Hoover

Step-by-Step Navigation Guide

Morning Commute to Downtown (7:00-9:00 AM)

  1. Check Traffic Apps: Before departure, check Waze or Google Maps for real-time conditions
  2. From West via M-14: Exit at Main Street if traffic is moving; otherwise continue to Barton Drive exit
  3. From East via I-94: Use exit 180 (State Street) for downtown south, exit 177 (Maple Road) for downtown north
  4. Parking Strategy: If downtown structures are full, try Kerrytown area (4th Ave) or AAATA Park & Ride
  5. Final Approach: Use one-way streets (William, Liberty, Huron) for faster movement

Evening Commute from University Area (4:30-6:30 PM)

  1. Departure Timing: Leave before 4:15 PM or after 6:30 PM to avoid worst congestion
  2. Northbound from Central Campus: Use Thompson Street to Fuller Road to Huron Parkway
  3. Southbound from Medical Center: Use Observatory to Washtenaw, then switch to Stadium if congested
  4. Westbound Options: Miller Avenue to Maple Road better than Stadium to Main
  5. Highway Access: For US-23 North, access via Geddes Road rather than Washtenaw

  1. Arrive Early: Minimum 2.5 hours before event start for parking
  2. Parking Alternatives: Consider Briarwood Mall shuttle or Kerrytown area parking
  3. Post-event Exit: Plan to stay downtown for dinner or wait 90+ minutes before departing
