We looked for places where that philosophy could be implemented without jeopardizing safety, convenience or mobility, and we found plenty. It's still a large need, but it's certainly more manageable than the original figure. And it helps assure that total reconstruction projects are designed and funded only when that is truly the most appropriate treatment for a particular section of roadway. In addition to those efforts, we've identified a strategy for addressing the backlog in a fair, equitable manner. With help from a special advisory committee, composed of RTAC members from around the state, we've devised a formula to distribute available funding across the state based on the amount of travel on highways that are part of the backlog and the relative cost of improvement.
Bridges are another issue of concern.
Nearly 10 percent of Maine's 2,810 traditional bridges are over 70 years old. One hundred of them require immediate attention. As we address those needs, the Department also is refining its system for managing our bridges, assuring that the most appropriate treatment to them occurs at the best possible time to give us the highest benefit for the cost. The funding levels provided under TEA-21 offer some encouragement that we will be able to address what was a growing area of strong concern. As important as they are, highways and bridges won't get all our attention.
