Gov. Rick Snyder says a proposal by Republican House leaders to spend $500 million annually on roads is a good first step toward much-needed changes, but says it's less than half of his spending target.

The Republican governor says a structural funding change to improve road maintenance could save lives and money. He calls the proposal ``very constructive'' and says it needs further discussion.

Republican House Speaker Jase Bolger says he agrees with Snyder that Michigan roads need $1.2 billion annually, but the proposed changes are better than one-time funding allocations the Legislature has made.
