129th Avenue Road & Safety Improvements

Update – April 27, 2022

Paving slated for first week of May

Final paving along SE 129th is anticipated to be carried out the first week of May. Provided weather holds, crews will continue to keep the roadway closed between SE Mountain Gate Rd. north to SE Scott Creek Lane and vehicles will continue to be routed via detour to accommodate the work. Please note, scheduling may change in the event of inclement weather by way of heavy rain.

One of the few major thoroughfares leading into an established area of the City, this project serves to increase travel safety for all modes of transport along this particular roadway.

Paving planned for SE 129th Avenue

 

The stretch of roadway between SE Mountain Gate Rd. north to SE Scott Creek Lane is slated to temporarily close this month beginning Monday, Apr. 4 to accommodate paving efforts that could not be completed during the project’s initial work. A traffic detour will be enacted to redirect vehicles during this time. Once paving is carried out, only a handful of additional safety improvements for this long-awaited project will remain, including adding a concrete median at the new pedestrian crossing at Scott Creek Trail. The road is anticipated to remain open at that time with flaggers utilized to direct traffic.

The upcoming closure is anticipated to last several weeks with any remaining tasks slated to be substantially complete by May 1.

It’s been quite the process, but SE 129th is open! Crews began letting traffic through in the late afternoon of Feb. 14. Mayor Tom Ellis (second from right), Council President David Golobay (center), and Public Works Director Chris Randall (far left), met up with the lead engineers and design team to commemorate the occasion. This project has been an important one as it serves to increase visibility and travel safety for motorists, pedestrians, and bicyclists. Though initially slated to be completed by end of Fall 2021, the project faced several delays due to supply chain challenges and bouts of inclement weather. Residents are asked to please keep in mind this stretch of roadway is still an active construction site and there may be intermittent delays due to construction flagging as some additional work is completed in the months ahead.


The stretch of roadway from Mountain Gate Road to Scott Creek Lane is a narrow winding roadway with limited visibility and lacks roadway shoulders causing additional safety concerns for pedestrians, bicycles, and vehicles. Because of this, the City was awarded a grant by Metro in March of 2014 to come up with a plan to address these issues. It has been a very complicated and lengthy process.  Along with the design of the roadway, retaining walls, pathways and utility undergrounding, time was required for property acquisition, tree removal and public involvement.

Fast forward to Spring of 2021 and that has all be completed, Elting Northwest, Inc. has been awarded the contract, and project construction is tentatively scheduled to begin.

CONSTRUCTION/ROAD CLOSURE SCHEDULE: June 3, 2021 through December 2021

PROJECT UPDATES

Road Closure & Detour


The proposed project will involve street widening and re-striping to allow for the creation of bike lanes on both sides of 129th Avenue. A retaining wall of varying height up to 10 feet will be constructed behind the proposed sidewalk as an added safety measure.  Additionally, a pedestrian crossing signal will be installed at the intersection of 129th Avenue and Scott Creek Lane.

More specifically, this project will consist of the following improvements:

  • Shared use path on the east side of the roadway for bike and pedestrians
  • New southbound bike lane
  • Retaining walls and fencing
  • New asphalt pavement overlay
  • Undergrounding of overhead utility lines
  • Installation of additional streetlights along the roadway
  • Stormwater system improvements including water quality treatment of surface runoff with green street planters
  • Pedestrian crossing using a rectangular rapid flashing beacon (RFFB) at Scott Creek Lane
  • Bike lane and crosswalk striping and symbolization

Although there are a lot of us who don’t like to see trees cut down, it is important to note that the City has a robust tree replacement requirement and tree permits are required for any type of tree removal. As a recognized Tree City USA, Happy Valley is truly committed to ensuring the City’s tree canopy remains healthy and strong. To this end, the City has worked closely with the City Arborist to ensure these removal efforts were carried out carefully and complied with the federal regulations of the Migratory Bird Treaty Act (MBTA), which requires any removal be completed prior to Mar. 1.

Roadway improvements on 129th Avenue are being funded by a grant issued by Metro. Securing these funds was a united effort made possible by not only the City, but by residents from the area, teachers, and business owners, who advocated strongly for these increased safety measures.
