Construction Update: June 26, 2020

Upcoming Closures

June 28 & 29: 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 CenturyLink utility lines. Workers will also be placing falsework columns adjacent to the highway which will support the new bridge during construction. Traffic will be detoured around the work area using the I-205 on- and off-ramps at Sunnyside Road.

June 28 – July 1: Crews will be completing night work on Sunnyside Road.  Traffic will be maintained through the work areas, but there may be intermittent delays.  If you typically travel through this area during nighttime hours, we would encourage considering alternate routes during this period.

General Project Update

Over the next several weeks, construction crews will be completing south side surface improvements between 84th Avenue and I-205, including new streetlights, curbs, sidewalks, cycle track, and ADA ramps.  This work must be done in preparation for upcoming bridge widening work, which will add new pedestrian and bicycle facilities and a second eastbound left turn lane on the bridge to reduce congestion.

Safety Update

Lane closures on Sunnyside Road often change on a daily or even hourly basis and are dependent upon the needs of the construction work that is being completed that day. Because of this, it is difficult to provide real-time or even daily updates. Construction crew members strive to ensure that temporary lane configurations are clear using advance warning signage and traffic control devices such as paint, cones, and barrels. With these temporary traffic control measures in place, it is important for all drivers to pay close attention while driving and exercise additional caution around work zones. It is Clackamas County’s priority to create a safe environment for construction crews and members of the public!

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.

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

Continuing Construction Activities

Work at this time is focused on the I-205 Bridge overcrossing widening, adding pedestrian and bike improvements to the south side of Sunnyside Road, reconstructing medians, and project-wide traffic signal and street lighting improvements.

I-205 Bridge Overcrossing – Widening is underway

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 of 2020 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 is 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.
