Please use caution when using trails!
Be aware that rain and high water can leave trails and roads a bit of a mess with hazards like downed trees, landslides, and flooding. Portland Parks & Recreation addresses weather related impacts as soon as resources allow, but may not be able to respond immediately or forecast where the next hazard will occur. Please use extra caution on trails and roads!

Columbia Slough Trail

The city constructed the Triangle Lake Lagoon just north of the Columbia Boulevard Wastewater Treatment Plant in 1970 to store and treat solids produced during the wastewater treatment process. Environmental Services is working on a long-term lagoon reconstruction project. Phases three and four of the project have begun and will continue until the end of 2020. During construction, the Columbia Slough Trail may be intermittently closed. Trail users can detour to Columbia Boulevard south of the plant and the trail segment east of the plant. The city posts signs and maintains a recorded hotline (503-823-1993) to advise trail users of periodic closures during the lagoon reconstruction project. For more information, please visit the BES Lagoon Reconstruction and Trail Closure Alert.

A portion of the trail will be closed to all users during weekdays from 7:00am to 5:00pm beginning November 1 through 7, for paving. It will remain open on weekends and will be open from 5:00pm to 7:00am. The portion of the trail that will be closed is on the north side of the Columbia Slough on the west side of the pedestrian bridge to North Portland Road.

There may be interruptions in access to the pedestrian and bicycle bridge over the Columbia Slough between the CBWTP and the Lagoon due to the paving project.

Foley-Balmer Natural Area

The bridge across Tryon Creek in the Foley-Balmer Natural Area has been removed due to structural concerns. To detour, please use SW Broadleaf Drive to connect SW Lancaster Road and SW 18^th Place or SW Maplecrest Drive. Please follow the recommended detour. Crossing the creek is unsafe and causes streambank erosion and damage to riparian vegetation.

Forest Park 

Wildwood Trail
Parts of the Wildwood Trail are closed from March 25, 2019 through fall 2019 during the construction of the Barbara Walker Crossing, a pedestrian bridge over West Burnside Road. The Wildwood Trail is closed to the south of Burnside for about 1,000 feet within Hoyt Arboretum, and north of Burnside to Verde Vista Trail (towards Pittock Mansion). The trail closures will be in place for the duration of construction. There are no detours at this time. Click here for a map showing trail closures.

Sellwood Gap - SE Umatilla to 13th Avenue Trail Project

Located in SE Portland, the Sellwood Gap – SE Umatilla to SE 13th Avenue trail project will help close the gap between the Springwater on the Willamette Trail with the Springwater Corridor Trail by providing an off-street rail-with-trail shared-use 12-foot path parallel to the Oregon Pacific Railroad mainline track from SE Umatilla to SE 13th Avenue.

Springwater Corridor

Temporary closures starting in May 2019 - Thanks to funding from the Parks Replacement Bond, two bridges along the Springwater Corridor will be repaired or replaced this summer. This will require temporary closures of the trail at two locations. During construction, the following detour routes will be in place. If you live or work on either detour route, please drive with caution, as you will see an increase in bicycle and pedestrian traffic. Thank you for your patience while we improve your trail!

Partial trail closure at the intersection of SW 7^th Street (Gresham) for approximately 3-5 weekdays between September 11 - 25, 2019. This temporary closure will only impact the northern branch where the Trail divides at this intersection. The southern branch of the Trail at this intersection will remain open and accessible to bicyclists and pedestrians.

A detour in effect for approximately 1-2 weekdays between September 26 – October 25, 2019. This temporary closure will impact the Trail from SW Walters Drive to SW 7^th Street (Gresham). Signage and detour route will be in place so that bicyclists and pedestrians can make informed decisions about alternate routes during this temporary closure. 

Between SE 45th and 55th Avenues
Bridge #48 located near the Johnson Creek Boulevard trailhead at SE 45th Avenue and Johnson Creek Boulevard will be replaced. It is the original wooden trestle bridge from the Springwater Division Line rail developed in the early 1900s with footings in Johnson Creek. The new bridge will be constructed with steel and concrete, and its footings will allow for clearer passage of Johnson Creek, which will improve fish habitat and reduce debris accumulation. Construction is expected to start in mid-May 2019, with completion in November 2019. Read more.

Between SE 174th Avenue and Circle Avenue
Bridge #140 spans 114 feet and crosses Johnson Creek near Circle Avenue. The western half of the bridge's structure was replaced with steel in 2006 due to deterioration, and the timber decking was salvaged and reused. The decking has now reached the end of its service life and is presenting a hazardous condition to trail users. It is slippery, uneven, and has large gaps.The decking will be removed and replaced with asphalt. The handrail will be salvaged and reinstalled by the contractor. Construction is expected to start in mid-May 2019, with completion in six to eight weeks. Read more.

Willamette Park

The entrance at SW Nevada Street is currently closed at the request of ODOT Railroad Authority until federally required infrastructure improvements can be made. We urge park users to use alternate park entrances on SW Miles Street or SW Nebraska Street. Portland Parks & Recreation continues to work on improvement measures with our partners at the Portland Water Bureau, Portland Bureau of Transportation, Trolley Consortium, and will provide updates as available.
