Read the weekly construction news for traffic impact information, updated every Friday.

Nov. 25, 2014 update:  Significant construction this year on Oak Street and Baseline Street is complete.  Double lane closures are not planned until 2015.  Intermittently through December 2014, the contractor will be adjusting manholes and inlets and performing various construction activities. There will be intermittent single lane closures on Baseline Street between 10th Avenue and 1st Avenue and on Oak Street from Dennis Avenue to 10th Avenue to complete this work.

Driveways into and out of businesses and residences on Oak Street and Baseline Street will have full access during any lane closures. The contractor will be placing “business open” signs at the driveway entrances so customers know to still patronize businesses.

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.

Project Information
ODOT, in partnership with the City of Hillsboro, began construction in June 2013 on a $14 million paving and utility project on TV Highway (OR 8) from Minter Bridge Road to SW 331st Avenue. This stretch includes 10th Avenue, Baseline Street and Oak Street through downtown Hillsboro. Work includes:

•Grinding, reconstructing, paving and restriping TV Highway from Minter Bridge Road to SW 331st Avenue [paving from Minter Bridge Road to Maple Street and from Dennis Avenue to 331st Avenue was complete in 2013]

•Significantly upgrading the City’s water and stormwater systems. Portions of the City’s water and storm pipes will be entirely replaced in downtown Hillsboro [water work is complete as of June 2014; the majority of the stormwater replacement is complete with the remaining amount completed in 2015]

•Improving more than 100 ADA ramps (accessible curb ramps), primarily in downtown Hillsboro

•Repairing and paving the Dairy Creek Bridge (complete)

•Improving signage
TV Highway in this section is in poor condition and in need of repair and reconstruction.  In addition, the City of Hillsboro is including major utility upgrades on TV Highway as part of the project. The City’s water mains buried under Oak Street and Baseline Street are at least 60 years old and predominately steel pipe.  The joints between the steel pipes are aging and causing leaks.  Approximately two miles of new waterlines will be installed on this project as part of the annual pipeline replacement program.  The new mains and meters will ensure quality water service to hundreds of commercial, industrial and residential customers along TV Highway.
By making all the improvements in one cohesive project, ODOT and the City of Hillsboro will save tax dollars and increase efficiency.

Traffic Impacts and Schedule

Road users on TV Highway will encounter significant construction during the day and night from June 2013 to fall 2015. There will be delays and detours in place throughout construction, especially in downtown Hillsboro. Read the weekly construction news for the latest traffic impacts, updated every Friday.  The following traffic impacts are planned:

  • Lane closures may occur on TV Highway during the day or night, 7 days a week
  • There will be intermittent intersection closures along Oak and Baseline streets
  • There will be unavoidable temporary business and resident driveway closures, which will be communicated individually to businesses and residents during construction
  • Access to the main entrance and emergency room of Tuality Hospital will remain open at all times. There may be short detours, but temporary signage will direct motorists to the hospital.
  • TriMet service on TV Highway will be intermittently affected during lane and intersection closures. Any TriMet detours will be communicated on www.trimet.org and at the bus stops.
  • There will be intermittent on-street parking restrictions on Oak Street and Walnut Street throughout construction
  • During double-lane and intersection closures, large trucks will be detoured from Baseline Street to Walnut Street. On-street parking on Walnut Street may be limited in some sections to allow for wider trucks. To minimize truck noise on Walnut Street, flaggers will be used to move trucks through intersections without stopping. 
This will be a disruptive project on TV Highway. Considerable effort is being made to maintain business and resident access and minimize traffic impacts. Thank you in advance for your patience and please travel slowly and carefully through the construction.
Nighttime Noise
Due to high traffic volumes on TV Highway, most of the lane closures and construction activity will occur at night.  The contractor will be required to turn off truck backup alarms during nighttime work after 10 p.m.  Flaggers will be used to move trucks through sensitive intersections without stopping, which will help reduce noise. A 24-hour noise hotline is available to be called at all hours should a noise concern arise. That number is 503-412-2356.  ODOT staff will be available to answer immediate noise concerns during nighttime work by calling the noise hotline.

TV Highway Paving Project: 331st Avenue to Quince Street

Construction finished in May 2013 on a project to grind and pave OR 8 (Baseline Street and Pacific Avenue) from 331st Avenue (just west of Hillsboro) to Quince Street (OR 47) in Forest Grove. This included the Baseline/Adair couplet in Cornelius. The eastern half of the Cornelius couplet was not paved because it was recently paved as part of a City project. In addition to grinding, paving and restriping the road, the contractor:
  • Repaired pavement
  • Upgraded sidewalk curb ramps to Americans with Disability Act (ADA) standards
  • Made improvements to the east side of the OR 8/Quince Street (OR 47) intersection including:
    • Striping a crosswalk across OR 8 at Quince Street/OR 47 on the east side of the interchange
    • Adding a pedestrian signal for the new crosswalk
    • Adding a raised pedestrian island at the south end of the new crosswalk
