The Worst Traffic Corridors During Rush Hour


One of the most notorious traffic corridors during rush hour in Seattle is Interstate 5 (I-5). This major highway runs from the Canadian border all the way to the Mexican border, passing through Seattle along the way.

During morning rush hour, I-5 can become incredibly congested, with long delays and slow-moving traffic. Commuters traveling southbound from Northgate to Downtown Seattle often experience the worst of it.

According to the Washington State Department of Transportation, the average travel speed during morning rush hour on this stretch of I-5 is only 15 miles per hour.


Another congested traffic corridor during the morning rush hour is Interstate 90 (I-90). This interstate connects Seattle to the eastern suburbs and beyond. Commuters traveling westbound on I-90 from Bellevue to Seattle often face heavy traffic and delays.

The bottleneck near the I-90 and I-5 interchange is particularly problematic, causing backups and frustration for drivers. It’s not uncommon for the average travel speed on this section of I-90 during morning rush hour to drop below 20 miles per hour.


State Route 520 (SR-520) is a key route for commuters traveling between Seattle and the Eastside, including cities like Redmond and Kirkland. During morning rush hour, SR-520 experiences significant congestion, especially in the westbound direction.

The bridge that carries SR-520 across Lake Washington is a major chokepoint, causing delays and backups. According to the Washington State Department of Transportation, the average travel speed on SR-520 during morning rush hour can be as low as 25 miles per hour.

Aurora Ave N

Aurora Avenue North, also known as Highway 99, is another traffic corridor that becomes heavily congested during the morning rush hour in Seattle. This road runs parallel to I-5 and serves as a major north-south route for commuters.

The stretch of Aurora Ave N between North 85th Street and Downtown Seattle is particularly problematic, with slow-moving traffic and long delays. Commuters traveling on this section of Aurora Ave N during morning rush hour often experience frustrating stop-and-go conditions.

Mercer St

Mercer Street, located in the heart of Seattle, is notorious for its traffic congestion during morning rush hour. This east-west corridor connects Interstate 5 to Seattle’s South Lake Union neighborhood.

The combination of high volumes of commuter traffic and the presence of large employers in the area, such as Amazon, contribute to the congestion on Mercer St. Commuters traveling eastbound on Mercer St often face significant delays and slow-moving traffic.

When planning your commute in Seattle, it’s important to be aware of these notorious traffic corridors during morning rush hour. Consider alternative routes or adjust your schedule to avoid the worst of the congestion.

Tips for Navigating the Morning Commute

Allow Extra Travel Time

One of the most important tips for navigating the morning commute in Seattle is to allow extra travel time. The morning rush hours in the city can be quite hectic, with heavy traffic and congestion. It’s always a good idea to leave early and give yourself some buffer time to account for unexpected delays.

This way, you can start your day on a stress-free note.

Use Public Transportation or Carpools

Another great tip for navigating the morning commute is to consider using public transportation or carpools. Seattle has an extensive public transportation system, including buses, light rail, and ferries.

By opting for public transportation, you can avoid the hassle of driving in traffic and parking. Carpooling is another eco-friendly and cost-effective option that can help reduce congestion on the roads.

Shift Your Hours Earlier or Later if Possible

If your work schedule allows for flexibility, consider shifting your hours earlier or later to avoid the peak morning rush hours. By starting your day before or after the rush, you can experience a smoother commute with less traffic.

This can significantly reduce your stress levels and make your morning commute more enjoyable.

Avoid Aurora Ave and I-5

Avoiding Aurora Ave and I-5 during the morning rush hours can save you a lot of time. These two major highways in Seattle are notorious for heavy traffic congestion during peak hours. Consider taking alternative routes or side streets to bypass these areas and reach your destination faster.

Apps like Google Maps or Waze can help you find the best alternative routes based on real-time traffic data.

Check Traffic Reports Before Leaving

Before heading out in the morning, make it a habit to check traffic reports and updates. There are several websites and mobile apps that provide real-time traffic information for Seattle, such as the Washington State Department of Transportation’s website (www.wsdot.com) or local news stations.

By staying informed about the current traffic conditions, you can plan your route accordingly and avoid any major delays.

Have Contingency Routes Planned Out

Lastly, it’s always a good idea to have contingency routes planned out in case of unexpected traffic or road closures. Familiarize yourself with different routes to your workplace and identify alternative options that you can take if needed.

This way, you won’t feel stuck or stressed if your usual route is experiencing heavy traffic or construction delays.

How Weather, Events, and Holidays Impact Rush Hour

Rush hour in Seattle can be greatly influenced by various factors such as weather conditions, major sporting events, concerts, and holidays. Understanding how these factors impact traffic patterns can help commuters better plan their morning schedules and avoid unnecessary delays.


Seattle is notorious for its rainy weather, and this can have a significant impact on morning rush hour. When it rains, traffic tends to slow down as drivers become more cautious and road conditions become more hazardous.

The increased congestion on the roads can lead to longer commute times, particularly during peak morning hours. It is important for commuters to plan ahead and give themselves extra time during rainy days.

Major Sporting Events

Seattle is home to several professional sports teams, including the Seahawks (NFL), Mariners (MLB), and Sounders (MLS). When these teams have home games, it can lead to increased traffic congestion around the stadiums and surrounding areas.

The morning rush hour may be affected as fans travel to the games or if there are street closures in preparation for the event. Commuters should be aware of the game schedule and plan their morning commute accordingly to avoid getting caught in heavy traffic.


Seattle is a popular destination for concerts and music festivals, attracting thousands of fans from all over the region. When there is a major concert or festival happening in the city, it can impact the morning rush hour as fans travel to the venue.

The increased traffic volume near concert venues can lead to delays and longer commute times. Commuters should check the event schedule and consider alternative routes if necessary to avoid getting stuck in traffic.


Holidays, such as Thanksgiving, Christmas, and New Year’s Day, can have a significant impact on morning rush hour in Seattle. Many people have the day off work or school, leading to lighter traffic and shorter commute times.

However, there may be an increase in traffic in the days leading up to the holiday as people travel to visit family and friends. It is important for commuters to be aware of holiday schedules and plan their morning commute accordingly to avoid any unexpected delays.

For more information on traffic conditions and real-time updates, commuters can visit Washington State Department of Transportation’s website. This website provides valuable information on current traffic conditions, closures, and alternate routes, allowing commuters to make informed decisions when planning their morning commute.

Future Outlook for Rush Hours in Seattle

Population Growth

One of the key factors influencing rush hour traffic in Seattle is the city’s population growth. According to the U.S. Census Bureau, Seattle has experienced significant population growth over the past decade.

With more people moving to the city, it is expected that rush hour traffic will continue to increase in the coming years. The demand for transportation options and the strain on existing infrastructure will likely contribute to longer and more congested morning rush hours.

Transportation Infrastructure Investments

To address the growing traffic congestion in Seattle, the city has been investing in transportation infrastructure projects. These investments include the expansion of highways, the construction of new bridges, and the improvement of public transportation systems.

The hope is that these infrastructure improvements will help alleviate some of the traffic congestion during rush hour and provide commuters with more efficient and reliable transportation options.

Remote Work Trends

The COVID-19 pandemic has significantly impacted the way people work, with many companies and employees embracing remote work arrangements. As remote work becomes more common, there may be a shift in rush hour patterns in Seattle.

Instead of the traditional morning rush hour, we may see a more spread-out distribution of commuters throughout the day. This could potentially reduce congestion during the typical morning rush hours, as more people have the flexibility to start their workday at different times.

Commuting Pattern Shifts

Another factor that could influence the future of rush hours in Seattle is a shift in commuting patterns. As the city continues to grow and develop, there may be changes in where people live and work. For example, if more job opportunities become available outside the city center, we may see a shift in rush hour traffic to different areas.

Additionally, the availability of alternative modes of transportation, such as bike lanes and electric scooters, may encourage more people to choose these options instead of driving, further impacting rush hour patterns.


Morning rush hour in Seattle can be a headache for commuters. However, being aware of the peak traffic times and planning accordingly can help you have a smoother commute.

While the early morning weekday hours of 6:30-9:30 AM tend to be the most congested, the worst traffic is typically between 7:30-8:30 AM. Allowing extra time, using alternate routes, and considering public transit can help bypass the brunt of the gridlock.

Rush hours may be impacted by weather, events, holidays, and ongoing transportation projects. Staying informed and being flexible in your commute times can help reduce frustrations. With some preparation and planning, Seattle’s morning rush hour doesn’t have to be the worst part of your day.
