Gov. Mike Pence has already appointed INDOT's deputy commissioner to take over for Karl Browning.
Weather permitting, pavement repairs along State Road 37 in Martinsville will begin Friday at 7 p.m. and continue through the summer months.
The line, which has faced several threats of closure in recent months, was set to cease operation at the end of this month if a deal wasn’t reached.
State and federal authorities must reach a decision before April 30 to save the Hoosier State Line railroad.
INDOT previously said service on the line would end April 1 because of a Federal Railroad Administration decision to classify the state as a railroad carrier.
The Indiana Department of Transportation has extended the passenger rail service's contract while long-term negotiations on the Hoosier State line continue.
INDOT officials say factors have changed since the initial route along State Road 37 was selected ten years ago
INDOT Commissioner Karl Browning doesn't recommend raising the gas tax but says an increasing number of bridges and roads in the state are in poor condition.
INDOT estimates the state will need at least $150 million annually over the next 10 years to adequately maintain its roads and bridges.
The Indiana Chamber of Commerce says the state faces a $750 million funding gap to maintain its roads. Changes to the state's fuel taxes could help.
