LOUISVILLE, Ky. (WDRB) – Thorntons has become the second retailer in the Louisville area to carry prepaid RiverLink transponders that let drivers avoid having to set up an account for the Ohio River toll-bridge network.

More than 300 Speedway stores in Kentucky and Indiana started carrying the transponders earlier this spring.

All Thorntons stores in Louisville and Jeffersonville, Ind., will sell the RiverLink “starter kits,” which include a transponder and a card that can be used to add more money to the transponders. Drivers can pay $20 to $500 for future tolls.

Besides those costs, Thorntons and Speedway charge a one-time $3 fee to get a transponder and $1.50 every time more money is added.

The effort is part of a promise Kentucky and Indiana made in 2015 to help offset the burden of bridge tolls on low-income and minority communities by placing transponders in retail outlets such as gas stations.

Tolling started in late December on three spans between Louisville and Clark County, Ind. It now costs $2 to $12 to cross the Interstate 65 Lincoln and Kennedy bridges, and the upriver Lewis and Clark Bridge that connects Indiana 265 and the Gene Snyder Freeway.
