It is estimated that there are 21.6 million truck trips made each year on Washington state highways. It is further estimated that 45% of transported freight originated from or is destined for a warehouse or distribution center within the state. The growing amount of congestion within the state of Washington has prompted concern over the state’s ability to anticipate and provide for current and future freight transportation infrastructure needs. The objective of this study was to determine freight mobility issues for the Warehouse/Distribution Center industry in Washington State. The scope of this project was primarily two-fold:, to assess the operations of Warehouse/Distribution Centers and to evaluate infrastructure adequacy, and identify deficiencies and investment needs related to transportation. The sample used for this study was compiled from local, county, state, and federal agencies.

The data collection method chosen for this study was a mail survey. The survey questionnaire and subsequent analysis were divided into four sections: Warehouse Operations, Inter-modal Systems, International Trade, and Other Transportation Related Issues.
