Virtual Open House

Hear from ODOT engineers and project managers about the construction of the OR 211 Dubarko Road Safety Project and the safety concerns that led to realigining Dubarko Road by visiting our virtual open house at www.OR211DubarkoSafety.org

Latest News

14-Day closure of Dubarko Road between Dahlager and OR 211 starts Monday, May 5, 2014.
Starting Monday, May 5, 2014, the contractor will close Dubarko Road btween Dahlager Court and OR 211 to realign the intersection and complete the waterline work. During the two week closure, travelers will follow a detour using Langensend Road to U.S. 26 Information regarding the dates of the closure will be available later this spring.
  
Construction Begins Feb. 10
K&E Excavating Incorporated of Salem, OR will begin construction on a safety improvement project for the Oregon Department of Transportation along OR 211 at Dubarko Road starting the week of February 10, 2014.
Work will include:
· Realigning the intersection of Dubarko Road with OR 211 to help drivers better see oncoming  traffic (see reverse)
· Replanting trees and native shrubs
· Installing radar “Your Speed” signs in the vicinity
· Replacing a city waterline

Construction Impacts

During construction you could expect up to 20-minute delays any time the contractor is working. Currently, the contractor expects to work daily from 7 a.m. to 5 p.m.
Construction impacts that will cause delays include:
· Flagging traffic through the work zone
· Lane closures
· Temporary traffic stops
Two Week Closure of Dubarko Road
Starting Monday, May 5, 2014, the contractor will close Dubarko Road btween Dahlager Court and OR 211 to realign the intersection and complete the waterline work. During the two week closure, travelers will follow a detour using Langensend Road to U.S. 26 Information regarding the dates of the closure will be available later this spring.

Schedule

· Tree felling –Feb. 10-14, 2014
· Tree felling will require traffic stops lasting up-to 20 minutes from 7 a.m. to 5 p.m. Travelers may want to consider and alternate route.
· Roadwork begins – Early March  2014
· Two-Week Closure of Dubarko Road – Monday, May 5, 2014
· Construction ends – October 2014

Construction Updates

Once construction is underway, updates to travel impacts will be available here and at www.TripCheck.com
  

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.
