Changes in Intermodal Transportation in Washington and Impacts on Road Infrastructure

This study evaluated the changes occurring in intermodal (piggyback) transportation and the impacts of these changes on the infrastructure system. Past and present structures of the intermodal system were documented both nationally and in the state of Washington. An on-site review of the remaining "hub" centers was conducted. It was found the impact of these changes is mixed. Traffic is up in some areas and down in the others. Ninety-two percent of the traffic is in western Washington locations but most of the infrastructure damage is at eastern or central Washington locations. Continued monitoring will be useful.
