The US state of Illinois is expected to spend $14.3bn for work on roads and bridges over the next ten years under a new bill signed by the Governor, which paves the way for $31bn of investment.

Out of the total amount planned for roads, the road repair programme will receive $10bn while $4bn will be spent on new constructions.

In addition, local road projects of the county will get $500m and $17.8m will be allocated for bicycle trails.

The state will pay the public works by selling bonds while the repayment amount will be collected from a variety of taxes and fees, plus a major gambling expansion.

The amount aimed at roadworks is the main outlay in the new capital bill.
