Using part of the state’s $5 billion windfall surplus on off setting toll hikes would be a “one-shot” use of the funds, something Senate Majority Leader Dean Skelos said he’s opposed to.

Skelos, in an interview, said the money gained from settlements with major financial institutions should be part toward infrastructure spending.

“That’s a one-shot deal,” Skelos said. “I think the infrastructure money should go toward exactly that — infrastructure.”

The state Thruway Authority last month approved a budget with a $36 million deficit.

Business groups are concerned that in order to make up the shortfall, the Thruway Authority will hike tolls across the system.

But at the same time, there is a concurrent push to use the billions of extra dollars the state has on construction projects, as well as shoring up roads, bridges and tunnels across the state.

“I believe the money should really be used for infrastructure because it’s a one-shot deal,” Skelos said. “It’s a one-shot and the next year people come back and ask for the money again. The infrastructure throughout the state is crumbling.”

Skelos added there have been no formal conversations yet with Gov. Andrew Cuomo as to what the money will be spent on.

Cuomo has indicated he plans to use the funds for a mix of infrastructure spending, encouraging local governments to share services and education spending with a bent toward accountability and performance.
