Work starts on bridge near Leach garden
Construction for a replacement bridge spanning Johnson Creek at Southeast 122nd Avenue has begun, which when completed will allow for better access to Leach Botanical Garden.
The original bridge had become a headache for Portland Bureau of Transportation crews, who were constantly working to stabilize the span to limit deterioration. Heavy rains and winter weather had caused it to become unstable and dangerous.
At first the 122nd Avenue bridge was only closed to vehicular traffic, allowing pedestrians and bikers to continue using the popular crossing, but this past summer the decision was made to move forward with a complete reconstruction.
The Oregon Department of Transportation and other local agencies allocated $2.5 million in Federal Highway Bridge Funds for the project, which began in September. Five new steel girders have been put in place, and the bracing and formwork systems are being installed to support the new concrete deck.
The bridge is expected to be completed in early 2019.
