Overcoming seasonal flooding to enable year-round access to the Fanno Creek Trail, one of THPRD’s busiest trail systems.
THPRD needed a new bridge to connect a parking area with the busy Fanno Creek Trail. Seasonal flooding made the bridge structurally unsafe for pedestrian crossing. 3J provided analysis of the floodplain and stormwater hydraulics to determine the optimal height for the bridge and location of footings. 3J also designed the paved ramps leading to the bridge.

On-grade ramps lead up to the bridge and permit universal access.
A pre-engineered bridge from Western Wood Structures was installed without direct impact to the waterway.
