All of the contract work on the TV Highway Paving Project from Minter Bridge Road to 331st Avenue is complete. Remaining work includes corrective ADA ramp replacement. Expect intermittent daytime and nighttime lane closures on Oak Street, Baseline Street and 10th Avenue.   Work is expected to be complete in 2016.


We ask for your patience as we work to improve the highway. This is the final stretch of construction on TV Highway for this project.

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 [complete]

•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 was completed in 2014; stormwater replacement was completed in 2015]

•Repairing and paving the Dairy Creek Bridge [complete]

Improving more than 100 ADA ramps (accessible curb ramps), primarily in downtown Hillsboro [complete except for a few that need corrective work]
•Improving signage [complete]
•Reconstructing and repaving 1st Avenue from Baseline Street to Walnut Street[complete]
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 spring 2016. 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.
