Questions
Which roads does TollCast cover?
I-66 Inside the Beltway — live price, deal verdict, and week planner. I-495 and I-395 are coming soon.
What does the deal verdict mean?
Every live price is scored EXCEPTIONAL → HORRENDOUS by comparing it to the historical average for that exact 15-minute window on the same day of week. EXCEPTIONAL means you're paying well below typical — great time to go. HORRENDOUS means you're being charged far above the usual rate for this time slot.
What does Pro add?
TollCast Pro unlocks push alerts ("tell me when I-66 drops to GOOD DEAL or better"), the week planner with actuals overlay, historical stats, widgets, and the forecast — the "should I leave now or in 20 min?" call. A single peak I-66 toll runs $12–$40. If Pro helps you skip one surge a month, it's paid for itself.
How do you know what "typical" is?
TollCast has been logging I-66 pricing every 5 minutes since late 2018 — over six years of data. The "typical" curve is the average price for that exact 15-minute window, same day of week.
Does it work on weekends?
I-66 is free on weekends — TollCast shows "Free" and won't bother you with alerts.
Is there an Android app?
Not yet, but we're working on it. Leave your email above and we'll let you know.
