Best Alternative Routes & Navigation Strategies
East-West Corridor Alternatives
| Primary Road | Best Alternative | Distance Difference | Time Saved During Rush Hour |
|---|---|---|---|
| I-10 (Central Tucson) | Grant Road or Speedway Boulevard | +1.2 miles average | 12-18 minutes |
| Broadway Boulevard | 22nd Street or Glenn Street | +0.5 miles average | 8-15 minutes |
| Speedway Boulevard | Ft. Lowell Road or Glenn Street | +0.8 miles average | 5-10 minutes |
North-South Corridor Alternatives
| Primary Road | Best Alternative | When to Use | Special Notes |
|---|---|---|---|
| Oracle Road | Stone Avenue or La Cholla Boulevard | Weekdays 4:00-6:30 PM | Stone has fewer traffic signals north of Grant |
| Campbell Avenue | Country Club Road or Tucson Boulevard | University peak hours (7:30-9:00 AM) | Country Club has dedicated turn lanes |
| Kolb Road | Harrison Road or Pantano Road | When Kolb has construction | Pantano has better traffic light synchronization |
Specific Route Recommendations
- Airport to Downtown: Use I-10 → 22nd Street exit (not Broadway) during peak hours
- Northwest to Southeast Tucson: Ina Road → La Cholla → 22nd Street avoids I-10 entirely
- University Area: Use 6th Street instead of Speedway during school hours
- Rush Hour Bypass: The Aviation Parkway connector between Broadway and 22nd Street is often underutilized
Real-time traffic monitoring is available through the Arizona 511 system, which provides camera views and incident reports for major Tucson roads.

Frequently Asked Questions
What are Tucson's absolute worst traffic times?
A. Weekday mornings 7:00-9:00 AM and afternoons 4:30-6:30 PM are Tucson's peak traffic hours. Interstate 10 and Broadway Boulevard experience the most significant delays during these times, with speeds sometimes dropping to 15-25 mph on normally 45 mph roads.
What's the best alternative route to I-10 during rush hour?
A. The most reliable alternative is taking surface streets like Grant Road or Speedway Boulevard for east-west travel, or Stone Avenue and Country Club Road for north-south movement. For longer north-south trips, Oracle Road to the west and Kolb Road to the east often have better flow than I-10 during peak congestion.
How much time should I add for Tucson rush hour commutes?
A. Add 20-40 minutes to normal travel times during peak hours. A 15-minute midday drive can take 35-55 minutes during weekday rush hours, depending on your route. Cross-town commutes (e.g., Oro Valley to eastside) may require 60-90 minutes during peak times versus 35-45 minutes off-peak.
Which Tucson roads have the highest accident rates?
A. According to Tucson Police Department data, Broadway Boulevard between Kolb Road and Craycroft Road, Grant Road near Oracle Road, and I-10 near 22nd Street have the highest accident frequencies. These corridors average 150+ accidents annually, primarily rear-end collisions during peak hours.

A. Tucson has limited HOV lanes. The main one is on I-10 between 22nd Street and Prince Road, operating weekdays 6:00-9:00 AM and 3:00-6:00 PM for vehicles with 2+ occupants. Some on-ramps have bypass lanes for HOV vehicles during peak hours.
