Indiana Gov. Mike Pence is set to make what his office calls a major infrastructure announcement.
The Republican governor's announcement scheduled for Tuesday afternoon comes amid recent political sparring with Democrats over state highway conditions.
Pence said in August he was considering whether some of the state's $2 billion in reserves should be spent on highway improvements. Those comments came during the month-long emergency closure of an Interstate 65 bridge near Lafayette that forced drivers to take a long detour off the highway.
Democrats have persistently criticized Pence for underfunding highway maintenance, leaving the state with many roads and bridges in poor condition.
The Pence administration has said accusations of the state's infrastructure crumbling are irresponsible scare tactics. The state has spent about $600 million on highway infrastructure improvements and raised transportation spending every year since Pence took office, the Indiana Department of Transportation said.
