Oregon Highway 8
Sept. 27 - Oct. 4, 2014 *
*Schedules are subject to change due to weather and site conditions.
Oregon Highway 8 (Tualatin Valley Highway), Minter Bridge Road to 331st Avenue
Project Description: ODOT and the City of Hillsboro are partnering on a paving and utility improvement project on Tualatin Valley (TV) Highway (OR 8) between Minter Bridge Road and 331st Avenue. Work on TV Highway involves grinding, reconstructing, paving and restriping; significantly upgrading the City’s water and storm water systems; improving more than 100 ADA ramps (accessible curb ramps); and repairing and paving the Dairy Creek Bridge.
The contractor has added crews over this summer and plans to complete a significant amount of work by October 2014. On TV Highway and some side streets, road users should plan for congestion, delays and uneven road surfaces. There is increased traffic enforcement in the area.  
Traffic Impacts: Baseline Street: Reconstructing and repaving work is underway on nearly all three lanes of Baseline Street from 10th Avenue to 1st Avenue. This work will take place day and night, Monday through Saturday, with two lanes in a 2-block section closed on Baseline Street 24/7.  At night from 5 p.m. to 6 a.m., the side streets in the 2-block lane closure area may be closed at Baseline Street. This means that road users (at night) may not be able to turn onto or off of the side streets from/to Baseline Street.
  • The left lane of Baseline Street from 2nd Avenue to 1st Avenue will remain closed through the weekend as the contractor completes sidewalk and curb work.
  • Beginning Monday, Sept. 29, and continuing until Saturday morning, Oct. 4, the left and center lanes on Baseline Street between 2nd Avenue and 1st Avenue will be closed 24/7. Paving of this section is scheduled for Friday night, Oct. 3 (weather permitting). 
  • Also during the week of Sept. 29, the signals on Baseline Street at both 2nd Avenue and 1st Avenue will be disabled and flaggers will be controlling all directions of travel in those intersections.  Additionally, nighttime closures of 1st Avenue at Baseline Street in both directions are planned Tuesday night Sept. 30 or Wednesday night, Oct. 1 AND Friday night, Oct 3.  These closures will begin at 8 p.m. and continue until 5 a.m. the following morning.  A signed detour will be in place directing road users around the closures.
Access to the main entrance and emergency room of Tuality Hospital will remain open at all times, with the possibility of clearly marked detours. TriMet service on Baseline Street will be intermittently affected during this reconstruction work. Driveways into and out of businesses and residences on Baseline Street will have access during the lane closures, with the possibility of short closures.
Oak Street:  The contractor completed grinding and paving the left and center lane of Oak Street from Dennis Avenue to 3rd Avenue earlier this week.  The left and center lane of Oak Street from 3rd Avenue to 10th Avenue will be ground and paved beginning 5 a.m. Friday morning, Sept. 26. The work is weather-dependent and will be rescheduled if there’s rain.
Here are the specifics:
  • Friday morning, Sept. 26 at 5 a.m., the left and center lane of Oak Street from 3rd Avenue to 10th Avenue will be closed.  These two lanes will be closed continuously until 6 a.m. Saturday morning, Sept. 27, with the contractor working around the clock to finish the work.  The double lane closure will stop prior to 10th Avenue, allowing traffic to make all turning movements at 10th Avenue.
  • During these lane closures, the traffic on the cross streets from the north will not be permitted to turn onto Oak Street or continue straight across Oak Street.  Traffic on the cross streets from the south will be permitted to turn right onto Oak Street, but not continue straight.  Flaggers will be controlling traffic at all intersections.
  • On-street parking on the south side of Oak Street will not be permitted between 3rd Avenue and 10th Avenue during the paving.  Signs will be displayed indicating the no-parking zones.  Please do not park vehicles on Oak Street on Friday
  • Access to the main entrance and emergency room of Tuality Hospital will remain open at all times.  If a detour is necessary to the emergency room, the new route will be clearly marked
  • Driveways into and out of businesses and residences on Oak Street will have intermittent access during the lane closures.  There may be delays getting into/out of driveways if the contractor is actively working in front of the driveway. The contractor will be placing “business open” signs at the driveway entrances so customers know to still patronize businesses.
  • Over the next week, the left and center lane of Oak Street will be intermittently closed from Dennis Avenue to 10th Avenue as driveways are reconnected to the new pavement.
After October 2014, the contractor plans to take a winter break and return in spring 2015 to complete the remaining work by the end of 2015. The contractor and ODOT are working hard to minimize disruption as much as possible, but many impacts are unavoidable. There is increased traffic enforcement in the area.  Please drive cautiously and follow construction signage.
