U.S. 26

Aug. 2 - Aug. 9, 2014 *

*Schedules are subject to change due to weather and site conditions. 


U.S. 26 (S.W. Kelly Avenue), S.W. 1st Avenue to the Ross Island Bridge
Project Description: This project will replace the concrete pavement on the southbound Ross Island Way ramp from S.W. Arthur Street to the Ross Island Bridge, and make various bicycle and pedestrian safety improvements along S.W. Kelly Avenue on the west side of the Ross Island Bridge adjacent to the National College of Natural Medicine. The contractor is currently performing final work.
Traffic Impacts: No traffic impacts.
U.S. 26 (Sunset Highway) Brookwood Parkway/Helvetia Interchange
Project Description: The U.S. 26 Brookwood Parkway/Helvetia Interchange project will improve traffic flow and safety in the interchange area. Project elements include:
  • Constructing a new westbound U.S. 26 to southbound Brookwood Parkway exit loop ramp.
  • Reconstructing the westbound U.S. 26 entrance ramp from Helvetia Road.
  • Widening the Brookwood Parkway overcrossing to accommodate additional northbound and southbound lanes over U.S 26.
  • Extending the right-turn lane from northbound Brookwood Parkway to the eastbound U.S. 26 entrance ramp.
  • Adding sidewalks and bike lanes within the interchange area.
Traffic Impacts: The contractor will continue mobilizing their crane from the US 26 median to the south side of the highway. Note the following closure on eastbound US 26:
  • The contractor will perform a rolling slow down* on eastbound US 26 on Monday, Aug. 4 and Tuesday, Aug. 5 starting at 4 a.m. and will begin at the Jackson School Road interchange. *Note: the speed on the highway will be reduced to approximately 10 miles per hour at this time to give the crane enough time to cross from the highway.  Expect traffic delays up to 20 minutes. All work is scheduled to be complete by 5 a.m. 
The other currently scheduled work will take place during the day off of the roadway with little to no impact to the traveling public. 
Pile driving is continuing at the Brookwood/Helvetia overpass.  This is very noisy work due to the steel piling being driven into the ground with a diesel hammer on a crane.  Work will only occur between the hours of 7 a.m. and 7 p.m.  The pile driving is intermittent and will not occur continuously during the day.
Motorists should be aware of trucks entering and exiting eastbound US 26 from northbound Brookwood Parkway during the week.
The new temporary signals are now up and running at both ramp intersections.  Due to the temporary signal configuration for required construction staging, the westbound off-ramp is reduced to two lanes at the top of the ramp.  The dedicated right turn lane has been removed from service.
Please note: NW Groveland Drive is permanently closed at NW Helvetia Road.  NW Groveland Drive will be accessible from NW Groveland Road via NW West Union Road.
A speed reduction zone is currently in place on NW Helvetia Road/NW Brookwood Parkway from the NW Helvetia Road/NW West Union Road intersection to the NW Brookwood Parkway/NW Huffman Street intersection. The posted speed limit has been changed to 40 mph in the work zone.

U.S. 26 (Mt. Hood Highway), east of Kiwanis Camp Road to Oregon Highway 35
Project Description: Construction of safety improvements to prevent severe and fatal crashes on U.S. 26 from east of Kiwanis Camp Road to east of the Mirror Lake Curves and preserve the highway to Oregon Highway 35 is underway on Mt. Hood. Work on the nearly eight mile stretch of U.S. 26 includes:
  • Paving between Silent Rock and OR 35
  • Cutting back the slope along a 600 foot section at Map Curve to provide a 27 foot wide ditch for rocks to land away from the road
  • Cutting back the rock slope east of the runaway truck ramp to east of the Mirror Lake trailhead
  •  Highway widening to install a median barrier
  • Construction of a retaining wall to reduce impacts to existing trails from highway widening work
  • Extending the westbound passing lanes for a total of about 1,400 feet
Traffic Impacts: This week K&E Excavating will clear trees and begin excavation from the work area at Mirror Lake. During the week they will haul excavation materials to sites along Lolo Pass Road, Laurel Road, Trillium Lake Road and Road 31. Travelers should expect slow moving trucks on U.S. 26 entering and exiting from behind the barrier and along Lolo Pass, Trillium Lake and Laurel Roads.
Road 31 will also be closed Monday’s through Thursday’s to allow crews to place trees removed from the slope. Road 31 will be open Friday’s through Sundays.
Only one lane will remain open in each direction along U.S. 26 along a 2-mile section around-the-clock through October 31. Travelers should expect delays.
