Construction of Loop Trail in the Washington Park Arboretum begins

Community encouraged to visit and sign up for construction updates

Seattle Parks and Recreation and partners, University of Washington Botanic Gardens and the Arboretum Foundation, are happy to announce the beginning of construction of the Arboretum Loop Trail. The Arboretum Loop Trail is a 1.2-mile trail that will connect to Arboretum Drive, creating a 2.5-mile path through the Washington Park Arboretum and provide improved access to the flagship public garden. Seattle Parks and Recreation awarded the construction contract to Ohno Construction for the paved, multi-use Arboretum Loop Trail.

The Arboretum will remain free and open to the public throughout construction. Safety for visitors, contractors, volunteers and staff is the priority during construction of the Arboretum Loop Trail. We may temporarily close or reroute some trails when work is taking place nearby. To receive meeting notification and construction updates please visit

In June 2013, City Council approved $7.8 million from WSDOT to fund implementation of the Arboretum loop. This project, as outlined in the Arboretum’s Master Plan, is key in mitigating the effects of the upcoming replacement of the SR 520 Bridge. It fulfills the Master Plan’s three primary goals: conservation, recreation and education. It will also improve safety for pedestrians and bicyclists visiting the Arboretum. Additionally, the project restores portions of Arboretum Creek and nearby wetlands.
