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, though it may temporarily close or reroute some trails when work is taking place nearby. To receive meeting notification and construction updates, visit LoopTrail.seattle.gov.
In June 2013, the Seattle City Council approved $7.8 million from the Washington State Department of Transportation 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 will improve safety for pedestrians and bicyclists visiting the arboretum and restore portions of Arboretum Creek and nearby wetlands.
