Major asset categories

As part of our agency-wide asset management planning effort, we use information from the Statewide Transportation Asset Management Plan (STAMP) to communicate estimated asset replacement values and funding needs across the four major asset categories: Highways, Ferries, Intra-agency and Multimodal.

We present the information to the state Legislature as a key part of the annual State of Transportation presentation and the agency budget development process. This information represents estimated funding needed to achieve an acceptable level of performance at the lowest life cycle cost, not to achieve excellent condition.

Past versions of this information only included WSDOT’s estimated preservation needs. The 2020 update expands this data to WSDOT’s estimated preservation and maintenance needs. The maintenance numbers are based on the best information available at publication.

Highways

Highway assets include pavements, bridges and structures, hydraulics, barriers, roadside facilities and more. WSDOT manages approximately 18,700 lane miles of state highway, more than 4,000 different state-owned bridges and structures, and the world’s largest floating bridge (SR 520 floating bridge). The total replacement value of the Highways asset category is estimated at $123.4 billion.

Ferries

Ferries assets include vessels and terminals, 139 dolphins, 35 wing walls, 23 bulkheads, 40 movable bridges and more. The Ferries Division operates the largest ferry system in the country, with a fleet of 21 vessels carrying nearly 24 million passengers annually to 20 different ports. From Tacoma, Washington, to Sidney, British Columbia, Washington State Ferry routes act as a marine highway for businesses, tourists and daily travelers. The total replacement value of the Ferries asset category is estimated at $5.3 billion.

Intra-Agency

Intra-Agency assets include Information Technology (IT), the Transportation Equipment Fund (TEF), Capital Facilities and Real Estate Services (RES). Some assets include core technology service infrastructure, real estate, 108 fuel stations, 43 electric vehicle charging stations, 1,140 highway maintenance work trucks, about 980 buildings and over 600 sites. The total replacement value of the Intra-Agency asset category is estimated at $70.2 billion.

Multimodal

Multimodal assets include Rail, Freight & Ports (RFP), Aviation and Public Transportation divisions. Some assets include 129 hoppers (railroad freight cars), 297 miles of track, 15 airports, runways and runway lighting systems, 149 buses and 625 vanpools (the largest public vanpool fleet in North America). These numbers represent the assets owned or managed by WSDOT and are a part of the larger modal systems. The total replacement value of the Multimodal asset category is estimated at $685 million.
