Between August 19 – August 30, 2019, you may observe additional noise and vibration near the bridge site at SE 45th Avenue and Johnson Creek Boulevard. The construction crew will be pile driving steel foundations into the bank of Johnson Creek for the new bridge’s footings. All work will be done during the City of Portland’s Noise Code’s allowable hours of 8am-6pm, Monday-Friday.
We thank you in advance for your patience during this important work.
Bridge #48 (SE 45th Avenue)
Thanks to funding from the Parks Replacement Bond, Bridge #48 on the Springwater Corridor will be replaced, and that portion of trail will be stabilized. This bridge is located near the Johnson Creek Boulevard trailhead at SE 45th Avenue and Johnson Creek Boulevard. It is the original wooden trestle bridge from the Springwater Division Line rail developed in the early 1900s, with footings in Johnson Creek, and needs complete replacement. 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.
Update on construction start (07-11-19): Construction mobilization will start July 16, 2019, with expected completion in early December 2019. We had originally anticipated a mid-May start date. However, there is a lengthy timeline for the bridge fabricator delivery, so the contractor has chosen not to close off the trail and have no work happening. Mobilization will begin July 16 to remove the old bridge and prepare the site for the new delivery.
Much of the work directly in Johnson Creek is limited due to permit requirements on when in-water work can occur, which is why this work must occur during the summer months. We thank all the cyclists and pedestrians for their patience while we improve this segment of the Corridor.
Bridge #140 (SE Circle Avenue)
Bridge #140 decking replacement is a Phase 2 project of the Parks Replacement Bond. The bridge 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. The decking had reached the end of its service life and was presenting a hazardous condition to users. It was slippery, uneven, and had large gaps.
The decking was removed and replaced with asphalt. The rail was salvaged and reinstalled by the contractor. Construction started in June 2019 and was completed on August 1, 2019. The trail is now open for use again.
