LOUISVILLE, Ky. (WDRB) – The Indiana Department of Transportation won’t disclose why its top official in charge of Ohio River bridge tolls is no longer on the job.

Clint Murphy, who was the state’s director of tolling oversight, guided Indiana through the start of tolls late last year on three spans between Clark County, Ind., and Louisville. He had been in his position since at least 2013.

But as of Thursday, “Clint Murphy no longer works for INDOT,” agency spokesman Andy Dietrick said in an email. He declined to provide details surrounding Murphy’s departure.

Dietrick said the department plans to replace Murphy. Meanwhile, he said, the vacancy will have no effect on the state's oversight role.

"We currently have a number of employees who are engaged with the Ohio River Bridges and RiverLink tolling in various capacities," he said, adding that other managers will cover Murphy's duties until a replacement is found. 

Murphy did not return a phone message left Thursday.

Through a six-member board, Kentucky and Indiana have the ultimate oversight over toll policy for the RiverLink system, which includes the Interstate 65 Kennedy and Lincoln bridges, and the upriver Lewis and Clark Bridge. But much of the decision making had fallen to two state employees – Megan McLain, assistant general counsel for the Kentucky Transportation Cabinet, and Murphy.

McLain said in an email Thursday that she is now working with Jim Stark, the deputy commissioner for innovative project delivery for the Indiana Finance Authority. Stark has been in that role, which includes work on the bridges project, since 2013.

WDRB News has submitted a request under Indiana’s public records law for correspondence and other documents related to Murphy’s departure.
