Traveling I-90 in Washington State offers some of the most breathtaking views in the Pacific Northwest, from the lush landscapes of the Snoqualmie Pass to the urban vistas of Seattle. However, beauty often comes with danger, especially on this vital interstate that crosses the state. 

Awareness of the I-90’s hazardous areas is essential for every traveler aiming to ensure their journey is as safe as it is scenic.

Snoqualmie Pass

The Snoqualmie Pass is notorious for its rapidly changing weather conditions. One moment the sun could be shining; the next, a thick fog could reduce visibility to near zero. Winter months are perilous, with snow and ice making the pass treacherous. Travelers need to be wary of not just the slick roads but also the risk of avalanches. Ensuring your vehicle is equipped for winter conditions and staying updated on weather forecasts is crucial when traversing this section.

Spokane Valley

The stretch of I-90 through the Spokane Valley is known for its frequent lane shifts and merging traffic, especially near construction zones. These areas can be confusing and lead to sudden stops or lane changes, increasing collision risks. Paying close attention to road signs and signals and anticipating the actions of other drivers can help mitigate these dangers.

East of Snoqualmie

As you descend eastward from the Snoqualmie Pass, you enter a region abundant in wildlife. Deer, elk, and other animals frequently cross the interstate, posing significant risks, especially during dawn and dusk when visibility is low, and animals are most active. High-speed encounters with wildlife can be deadly, so it’s vital to stay alert, reduce speed, and heed wildlife crossing signs.

The Vantage Bridge

Crossing the Columbia River, the Vantage Bridge is a critical point on I-90 known for its high winds. These winds can surprise drivers, particularly those in high-profile vehicles like trucks and RVs. The bridge's narrow lanes offer little room for error, making it essential to maintain a steady speed and keep both hands on the wheel while crossing.

Downtown Seattle

Navigating I-90 through downtown Seattle presents a different set of challenges. Heavy traffic congestion, frequent lane changes, and ongoing construction work increase the risk of collisions. The complex network of exits and merges requires drivers to be extra vigilant and anticipate the movements of other road users to navigate safely.

Issaquah to Bellevue

The section from Issaquah to Bellevue is heavily trafficked, with urban sprawl contributing to a high volume of vehicles at almost all hours. The mix of commuter traffic, frequent on and off-ramps, and variable speed limits requires constant attention. Adapting to the flow of traffic and being prepared for abrupt changes is key to safe passage through this bustling corridor.

The Floating Bridges

The I-90 includes two floating bridges—the Lacey V. Murrow and Homer M. Hadley bridges—that carry traffic across Lake Washington. While these engineering marvels are stable, they present unique challenges, such as vulnerability to strong winds and limited escape routes in emergencies. Ensuring your vehicle is in good condition and being mindful of weather conditions is essential when crossing these iconic structures.
