OR 211 and Dubarko

Latest News

Design is progressing and construction could begin in late 2013. Starting March, 30, 2013, a contractor for ODOT will start to demolish the home on the southeast corner of OR 211 at Dubarko Road. Removing the house is necessary to allow for the new road alignment.

Thank you to the nearly 40 people who attended the public meeting in October 2012 at Sandy City Hall.

 

Project Overview

ODOT is designing a project to improve safety of OR 211 at Dubarko Road. Project elements include:

  • Improving the angle of the intersection and sight distance obstructions
  • Cutting back the embankment in the northeast quadrant of the intersection to improve the sight distance for drivers, which could help them judge gaps in traffic before turning.
  • Realign Dubarko Road to reduce the angle and maximize sight distance and improve safety.

The Problem at Dubarko Road

OR 211 at Dubarko Road is one of the top 5% high crash locations in the state. Between 2001 and 2010, 38 crashes occurred in this area. In the last four years of that period, between 2006 and 2010, 26 of those crashes occurred.

 
Crash data shows that most crashes involve vehicles crossing the intersection at Dubarko Road. In the nine year reporting period, one person died in a crash along this stretch of road and two people were seriously injured.
 
For information about crashes at OR 211 and Dubarko Road, here.
 
Of the 38 crashes, 21 were crashes where the angle of the intersection contributed to blocking the view of drivers. Police reports from the crashes on OR 211 at Dubarko Road indicate:
o         Drivers on Dubarko Road didn’t see vehicles on the highway
o         Drivers on OR 211 often report that driver on Dubarko Road “just pulled out in front of me.”
 
 

High Safety Risk Findings

ODOT along with the City of Sandy conducted a safety audit of OR 211 at Dubarko Road in October 2011 to identify potential safety risks contributing to the crashes and recommend improvements.
 
  • During the field review, vehicle speeds were consistently observed five to 10 miles-per-hour above the posted speed of 45 miles-per-hour.
     
  • The angle of the intersection at Dubarko Road and the embankment on the northeast side of the intersection contributes to limited sight of drivers turning onto OR 211.
o      Dubarko Road intersects with OR 211 at a 70 degree angle
o      When a driver from Dubarko Road commits to through or left turn movement, they almost immediately lose the ability to see the south leg of the intersection. This is because the driver’s vision is blocked by the center post of their vehicle due to the angle of the intersection
 
 
Safety Audit Findings

Safety Audit Recommendations

The recommendations to some of the high safety risk findings include:
§          Short-term solutions to be implemented before the safety project
o         Cut back vegetation from the slopes to assist with driver sight distance
o         Add speed reduction markings to decrease speed by giving drivers the impression that speed is increasing
 
ODOT maintenance crews have completed these improvements in the summer of 2012.
 
 

Safety Improvements Currently Under Design

  • Cutting back the embankment in the northeast quadrant of the intersection to improve the sight distance for drivers, which could help them judge gaps in traffic before turning.
  • Realign Dubarko Road to reduce the angle and maximize sight distance and improve safety.
 
These improvements are part of a safety project that will start construction in late 2013. Continue to check back here for more information as design progresses.
