CONSTRUCTION IS STARTING OCTOBER 2015!
Pre-construction Open House scheduled Wednesday, Oct. 14 from 4:30 - 6:30 p.m.
ODOT has completed the design of a project on TV Highway (OR 8) in Aloha to improve safety for people driving, walking, biking and taking transit between 182nd Avenue and 187th Avenue. Construction is expected to begin in October 2015 and be complete in fall 2016.
Please join the project team at an Open House on Wednesday, Oct. 14, 2015.
Drop in anytime from 4:30 - 6:30 p.m. to meet ODOT staff and learn more about the project, the construction schedule and traffic impacts.
The open house is at the International School of
Beaverton (17770 SW Blanton St, Aloha, OR 97078).

What are the construction impacts?
Road users should expect increased congestion, intermittent flagging and delays in the project area - day and night - throughout construction (from October 2015 to fall 2016). Please travel safely and follow construction signs. Daytime lane closures may occur on TV Highway and on 185th Avenue between 9 a.m. and 3 p.m. weekdays. All other lane closures will be at night. In addition:
BIKE RIDERS: The shoulders will be closed throughout construction and signs will direct bicycle riders to use the motor vehicle travel lane
PEDESTRIANS: There will be short-term sidewalk closures. A signed ADA-accessible pedestrian detour will be provided. Only one intersection corner will be closed at a time in order to maintain pedestrian circulation
TRANSIT USERS: Trimet bus stops in the project area may be temporarily closed/relocated
BUSINESS ACCESS: There will be unavoidable short-term driveway closures. ODOT will work individually with each
business to schedule the closures and ensure business access
TRUCK DETOURS: The right lane on northbound 185th Avenue approaching TV Highway will be closed for a short
period. A signed truck detour to head east from 185th Avenue will take drivers on Kinnaman Road, Farmington Road and 170th Avenue
NOISE: Residences and businesses adjacent to the project area may experience daytime and nighttime construction noise. A noise hotline - 503-646-0231 - is available 24 hours a day for reporting noise issues requiring immediate
attention. ODOT staff can be reached via the noise hotline
Why this project?
The crash rate in this section of TV Highway is very high, and is one of the top safety concerns in Washington County. Between 2009-2013, there were 156 crashes and 55% of those resulted in injuries. The most significant safety concern is the high number of rear-
end and turning crashes on TV Highway on either side of around 185th Avenue.
Although some of the crashes may be related to congestion in the intersection area, many crashes are happening outside commute hours when the intersection is not as congested. Rather than reducing congestion through expensive and impactful highway widening, ODOT plans to increase safety by minimizing vehicle conflicts.
The top safety concerns identified in the area are:
Numerous driveways on TV Highway and cross streets in close proximity to the TV Highway/185th Avenue intersection. Motorists turning left in and out of these driveways and streets create a high conflict potential
Poor visibility of roadway, traffic signals and signs due to short sight distance, lack of suitable street lighting and old, poorly placed signs
Transit stops in locations that cause backups and unpredictable driving patterns
What are the main project elements?
Install a raised traffic separator on TV Highway from 182nd to 187th Avenues. All turns will still be available at the 185th and 187th Avenue intersections. Left turns will be permitted into 182nd Avenue and the west driveway of Aloha Mall, but will be restricted to only right turns out onto TV Highway. This will help eliminate crashes due to left-turn conflicts
Install 49 new LED street lights on TV Highway from 178th Avenue to 192nd Avenue and on 185th Avenue from Alexander Street to Blanton Street which will help pedestrians see and be seen better (through a partnership with Washington County)
Move the bus stops in both directions on TV Highway to the far-side of the TV Highway/185th Avenue intersection and build bus pull-outs. This will improve signal operation & traffic flow and reduce rear-end crashes
Reconfigure the right turn from northbound 185th Avenue to eastbound TV Highway to a standard right angle intersection to lower speeds through the intersection, reduce rear-end crashes and improve safety of those walking and biking
Upgrade signs and add supplemental signal heads on TV Highway to improve driver expectation by providing clearer information
Add pedestrian countdown signals on TV Highway at 185th Avenue at all four corners so pedestrians will have more accurate information
Allow U-turns on TV Highway at 185th Avenue in both directions for motorists to safely access driveways rather than making left turns
TV Highway in the vicinity of 185th Avenue has been a top 5% Safety Priority Index System (SPIS) site for over ten years. SPIS is a tool ODOT uses to screen the state highway network and identify locations that have significant safety concerns. Locations are then ranked based on the frequency, rate and severity of crashes over a three-year period. Those locations in the top 5% are investigated further for mitigation options. The best candidates for safety projects are typically sites that rank high in terms of cost-effectiveness and mitigation options.
What’s been done so far?
ODOT conducted a Road Safety Audit (RSA)
in December 2011 on this section of TV Highway. An RSA is a formal safety evaluation by a multi-disciplinary team, considering the safety of all road users. The team spent two days on-site driving, walking and biking each movement and observing driver behavior and congestion.
The objective of the RSA is to identify potential safety issues, assess the safety risks and recommend solutions to mitigate the risks. The RSA team was composed of ODOT staff from various disciplines, Washington County staff, and emergency services. The RSA report includes detailed safety problems and solutions.
