A state lawmaker is worried the money the state made from the leasing of the Indiana Toll Road could run out sooner than expected.

Republican Rep. Ed Soliday of Valparaiso tells the Times of Munster the state needs to find a way to cover more than $5 billion in transportation needs. That number is growing by $800 million a year according to a Purdue University study.

Soliday chairs the General Assembly's committee studying the state's transportation and infrastructure needs. That panel next meets on Tuesday.

In 2006, Gov. Mitch Daniels leased the Indiana Toll Road to foreign investors for 75 years in return for $3.8 billion. The money was intended to pay for transportation projects over 10 years.
