Calculate Your Monthly Cost
- Pick your roads. Check mobilityauthority.com for your route.
- Count gantries. Most trips cross 2 to 4.
- Multiply by trips. Assume 20 workdays: 40 one-way passes.
- Example: 183 Toll commute (MLK + Loop 1, $1.55 + $1.46 = $3.01 round trip). 20 days: $60.20 monthly.
Frequent drivers hit higher. A 290 Toll full loop (Giles + ramps: $2.28 round trip) totals $91 monthly for 20 days.
