SE 122nd Ave Bridge Over Johnson Creek

Project Update - April 17, 2018

The design team and project partners have been hard at work planning, designing, and permitting the proposed bridge design. We are pleased to announce that all required project permits have been approved, the bridge design is complete, and the construction contract is in process.

 

Utility companies (Portland General Electric, CenturyLink, Portland Water Bureau, Northwest Natural Gas) will be working in the area throughout the Spring to prepare the site for removal of the bridge. Be prepared for minor traffic delays as this work gets underway.

 

The bridge construction contractor, Cascade Bridge, is anticipated to mobilize its equipment to the site on or around late June or early July.

 

 

Project Background

The bridge was damaged by heavy rains during winter storms and will remain closed to motor vehicles until a replacement bridge can be built, expected in 2019. The bridge sidewalk currently remains open for biking and walking.

“Public safety is our top priority and in this case to keep the public safe we need to limit access to the bridge until it can be replaced,” Portland Transportation Director Leah Treat said. “We understand a closure of this magnitude will be an inconvenience for the traveling public, and we will work to minimize the inconvenience in the coming weeks and during the construction period. We have made this decision after carefully considering the need for public safety. We’re thankful for funding recently approved by the state.”

Since January, PBOT crews have worked to stabilize the bridge site to limit the risk of further deterioration. In March, a committee of the Oregon Department of Transportation and local agencies allocated $2.5 million in Federal Highway Bridge Funds for replacement of the 122nd Avenue Bridge. The federal funds require a local match of $300,000, which PBOT will provide using general transportation revenue, which is mainly funded by parking revenue and the City’s share of state gas tax.

Travelers in the area should use alternate routes to travel between SE Foster Road and SE Flavel Street.

Local access will be maintained south of SE Foster Road and North of SE Flavel for residents and businesses. Access to the Leach Botanical Garden, a major destination in the area that is located next to the bridge, will also be maintained.

 

“Spring begins our busy season at Leach Botanical Garden, with weddings and events as well as casual visitors coming to enjoy the peace and beauty,” said David Porter, executive director of Leach Garden Friends, a non-profit that operates the garden for Portland Parks & Recreation. “We want people to know that our parking lot is open as normal and can be reached from the south via Flavel Street.”

 

The garden’s parking lot provides 32 spaces for visitors and is available south of the bridge. Visitors can walk across the bridge to reach the garden’s main entrance, just north of the bridge. A map with directions to the garden and the parking lot is available at the garden’s web site: leachgarden.org

 

PBOT crews have posted two detour routes during the bridge closure.
