Nestled under Seattle’s I-5 freeway, the Colonnade Mountain Bike Park has a rich history as the country's first urban mountain bike skills park. Since its inception in the early 2000s, and with its ups and downs, its transformation from a wasted space into an awesome resource for Seattle mountain bikers is still unfolding. Evergreen Mountain Bike Alliance just broke ground on a new asphalt pump track, including a small track for adaptive bikes and mobility devices.

In the 1980s and 90s, mountain biking faced significant restrictions in Western Washington. Advocates, led by Evergreen, known then as Backcountry Bicycle Trails Club, pushed for change. By the early 2000s, pro rider Simon Lawton identified the neglected land under I-5 as an opportunity for a legal, purpose-built mountain biking space. The vision took shape when we collaborated with Seattle Parks, WSDOT, and the Eastlake Community Council.

Construction began in 2005, and by 2007-2008, Colonnade featured trails with rock gardens, skinnies, jumps, and technical challenges. It provided a crucial training ground for bigger destinations like Whistler and Bellingham. Its popularity spiked, attracting riders and volunteers who helped maintain and improve the park.

As larger bike parks like Duthie Hill and Raging River emerged, Colonnade saw a decline in use. Meanwhile, challenges like increased homelessness and deteriorating features signaled the need for a refresh. In 2015, Evergreen partnered with the Eastlake Community Council to reimagine the park, shifting the focus to a local urban-friendly space with more accessible trails.

The future of the Colonnade revitalization focuses on inclusivity and sustainability, creating a space that welcomes riders of all skill levels and abilities. A large asphalt pump track will provide a low-maintenance, accessible riding experience, while beginner and family-friendly trails will offer a lower-risk environment for those new to the sport. An adaptive mountain bike (aMTB) track is designed to accommodate mobility devices, ensuring access for all riders. Kid-friendly dirt jumps will foster progression and build confidence in young riders. Beyond biking, the community-oriented design will integrate additional activities such as parkour, playgrounds, and bouldering, making the Colonnade a dynamic and engaging space for all.

Thanks to renewed interest, work parties, and grants, the next phase of construction is underway. Groundbreaking on the pump track will begin in March 2025.

Colonnade remains a vital part of Seattle’s mountain biking history. It is now evolving into a modern, community-focused recreation space for the next generation of riders. Stay tuned and get involved!
