Toll Road Costs & Savings Analysis
Miami-Dade Expressway Authority (MDX) Toll Rates
All rates shown for 2-axle vehicles with SunPass (20% higher with Toll-by-Plate):
| Road | Typical Segment | SunPass Cost | Time Saved | ROI During Peak |
|---|---|---|---|---|
| SR-836 (Dolphin) | NW 137th Ave to I-395 | $2.25 | 8-18 minutes | Good (if saving >10 min) |

*Variable pricing based on congestion - highest Friday PM.
Cost Comparison: Monthly Commuter
Scenario: Driving from Kendall to Downtown daily (20 miles each way)
- All Tolls (SR-874 + SR-836 + I-395): $9.50 daily × 22 days = $209 monthly
- Mixed (Tolls only PM): $5.25 daily = $115.50 monthly
- No Tolls (US-1/SW 40th St): $0 tolls but adds 45-60 minutes daily
Recommendation: Based on FDOT value of time studies, if your time is worth >$25/hour, peak hour tolls usually provide positive ROI.
Public Transportation Options
When Transit Beats Driving
Metrorail - Best Corridors
- Dadeland South to Government Center: 25 minutes (always) vs 25-60 minutes driving
- Cost: $2.25 each way vs $5-12 driving (gas + parking)

- Limitation: Limited coverage - only 2 lines serving specific corridors
Brightline (Miami to Fort Lauderdale/West Palm)

What is the best route from Miami to Fort Lauderdale during rush hour?
A. Use I-95 Express Lanes (tolled, but saves 20-35 minutes) or the Sawgrass Expressway (SR-869) as alternatives to regular I-95. For a free route, try US-441/FL-7 though it adds 15-20 minutes. The Brightline train (30 minutes) beats all road options during 4:00-7:00 PM.
How much are tolls on Miami highways?
A. Miami-Dade Expressway Authority tolls range from $0.50-$2.50 per segment. A full trip on the Dolphin Expressway (SR-836) costs approximately $2.25 with SunPass. The Florida Turnpike from Miami to Orlando costs about $20-25. I-95 Express Lanes use dynamic pricing from $0.50-$10.50 based on congestion.
What's the best way to avoid Miami International Airport traffic?
