Construction Update:  April 23, 2020

Friday, April 24

I-205 northbound and southbound will be closed at Sunnyside Road for night work beginning at approximately 10:00 PM and ending at 5:00 AM. The closure will allow workers to relocate overhead utility lines in preparation of widening the Sunnyside Road bridge to improve safety for cyclists and pedestrians.

Traffic will be detoured around the work area using the I-205 on- and off-ramps at Sunnyside Road. Sunnyside Road will remain open during the closure. Travelers are asked to slow down and use caution near the work zone.

Clackamas County prioritizes the health and safety of its employees, contractors, and the public during this time of public health concern. While construction is continuing for the CRC Mobility Project, know that Clackamas County has implemented social distancing requirements for all employees, including those working in the field. All employees are maintaining at least a six-foot distance to remain healthy while continuing work on this project to benefit the Clackamas Regional Center. 

If you have any questions about Clackamas County’s response to the COVID-19 pandemic, please visit for more information.  

All dates and activities are subject to change depending on weather or other variables.

Continuing Construction Activities

Work at this time is focused on preparing the I-205 Bridge overcrossing for widening, adding pedestrian and bike improvements to the south side of Sunnyside Road, and project-wide site preparation and tree removal where improvements are proposed.

Project Wide – Site preparation and tree removal to make way for new facilities

What:  Approximately 80 trees within the project area must be removed by the end of February to make room for widened roadways and multi-use paths in the coming year.

  • The trees being removed are incompatible street trees that have significantly damaged existing sidewalks
  • Existing trees and vegetation will be saved as much as possible, including the large oak tree on the east side of the overpass at Sunnyside Road
  • After roadway widening and multi-use paths are completed, new street trees will be planted throughout the project area that are more compatible with sidewalks, roads and utilities

When:  Tree removal must happen now to comply with the Migratory Bird Act, which requires all trees to be removed prior to March 1 to ensure that no nesting birds are harmed during construction.

Traffic Impacts:  None anticipated.  Flaggers may intermittently route pedestrians as trees are removed.

I-205 Bridge Overcrossing – Preparation for widening

What:  The sidewalk on the south side of I-205 Bridge overcrossing will be closed to allow for widening improvements on the south side of the structure.

When:  Beginning late January for approximately one (1) year

Traffic Impacts:  The sidewalk on the north side of the bridge will remain open.

Sunnyside Road (south side) – Construction of pedestrian and bike facilities

What:  The south side of Sunnyside Road (eastbound) between 84th Avenue and 93rd Avenue will be reduced from four to three travel lanes to provide space for pedestrian, bike, and stormwater facilities, and future landscaping and tree planting.

When:  Now through the end of the project, approximately late Fall 2021

Traffic Impacts:  Three eastbound travel lanes and accesses to businesses on the south side of Sunnyside Road will remain open.  The existing bike lane will be removed while the new bike facility is under construction. Signage will indicate “Bikes on Roadway” to alert drivers.  Temporary pedestrian routes around the work zone will be set up one block at a time to minimize out-of-direction travel for pedestrians.

84th Avenue – Partial closure for use as construction staging area

What:  The middle section of 84th Avenue between Sunnyside Road and Sunnybrook Boulevard will be closed to vehicular through traffic.

When:  Now through the end of the project, approximately late Fall 2021

Traffic Impacts:  Driveways into the Clackamas Promenade will remain open.  Sidewalks will remain open for pedestrians and available for use by cyclists.  82nd Avenue and 93rd Avenues are alternate routes for vehicular through-traffic between Sunnyside Road and Sunnybrook Boulevard.

80th Avenue– Reconstruction and repaving

What:  80th Avenue between Harmony Road and Southgate Street will be reconstructed and paved to provide better access and circulation.

When:  Now through Fall 2020

Traffic Impacts:  Access will remain open for local traffic, emergency vehicles, pedestrians, and cyclists.
