Why Study Tolling?

The Puget Sound region’s transportation needs far exceed available funding. Increasing traffic congestion and safety concerns over aging infrastructure is calling attention to the need for new revenue sources for transportation improvements. Tolling major highways and bridges has been suggested as a possible funding source for several major corridor projects in the region and as part of a regional funding package.
