Snow a major factor in 2019 state ferry ridership drop

SEATTLE – For the first time in seven years, annual ridership aboard Washington State Ferries declined in 2019, dropping by 880,000 customers – 3.2% – to 23.9 million. Severe winter weather, construction in and around ferry terminals and increased ferry and transit options, are considered the main reasons for the decrease.

SR 99 - NB Duwamish River Bridge - Select Grid Deck Replacement - Complete September 2020


During summer 2020, we replaced 14 steel panels, each one about 6 feet by 26 feet, on the roadway deck of the northbound SR 99 Duwamish River Bridge, commonly known as the 1st Avenue South bridge. This work keeps the bridge in a state of good repair. This highway is a critical route between cities like Burien, Normandy Park and SeaTac, and Sea-Tac Airport to Seattle, carrying about 62,000 vehicles each day.

How you benefit

Safety: This work increases traction on the bridge and provide a smoother, safer ride for travelers.

I-90 - SR 202 to Snoqualmie Valley Trail Bridge - Seismic Retrofit - Complete February 2021


We completed seismic retrofits that strengthened six bridges on I-90 between East Sunset Way/Highlands Drive Northeast in Issaquah and 436th Avenue Southeast in North Bend. Our contractor crews added steel “jackets” around columns that hold up the bridges that will help keep the columns from buckling in an earthquake. They also added supports to some cross beams that will keep girders from moving during an earthquake.

Needs & benefits

Expect an extra helping of passengers on state ferries over Thanksgiving weekend

SEATTLE – With nearly 350,000 people expected to ride a state ferry Wednesday, Nov. 27, through Sunday, Dec. 1, those who planned ahead will be thankful they avoided the busiest travel times this Thanksgiving weekend. Over the five-day period, up to 50,000 more people are projected aboard Washington State Ferries than a typical Wednesday through Sunday in November.

I-5 & SR 548 - Tributaries to California Creek - Fish Passage - Complete October 2020


During spring and summer 2020, we replaced four culverts in the area of I-5 and SR 548 north of Ferndale. The old culverts were narrow and kept fish from continuing to spawning grounds upstream.

To complete the work, our contractor built a bypass between the northbound and southbound lanes of I-5, then shifted traffic to have space to safely remove old culverts and install larger box culverts. The crews also replaced a culvert under Zell Road, just east of I-5. Finally, they replaced a culvert under SR 548 at Portal Way.

All done! Seattle's Alaskan Way Viaduct is history
