We don't know. Feasibility studies have examined the viability of $1/1.50 tolls and $2/$3 tolls for passenger vehicles. There has not been a publicly disclosed number for trucks, large or small. For comparison's sake, the Ohio River Bridges in Louisville are charging:
- With ezpass: $1 for frequent commuters, $2 for other cars, $5 for box trucks and $10 for tractor trailers.
- With registered license plate: $2 for frequent commuters, $3 for other cars, $6 for box trucks and $11 for tractor trailers.
- Without registered license plate: $3 for frequent commuters, $4 for other cars, $7 for box trucks and $12 for tractor trailers.
Louisville tolling authorities plan to raise rates a minimum of 2.5% each year:
To keep pace with inflation, the Tolling Body also approved an annual toll rate increase of 2.5 percent or the inflation rate as measured by the Consumer Price Index, whichever is greater. Once the initial rates had been in effect for at least one year, the increases would take effect July 1 each year thereafter.
