US 20 at Granger and Independence Road Safety Audit

New information!!

ODOT's Region 2 Traffic Manager has responded to the Road Safety Audit Final Report.  To learn how ODOT will address issues outlined in the report, click here.

ODOT is conducting a Road Safety Audit of U.S. 20 at Granger Avenue and Independence Highway because the intersections are among the top 5% of the worst crash sites in the state.  ODOT is committed to studying these intersections to determine the best safety improvements to implement.
Each year, the Oregon Department of Transportation identifies its top 5% of high crash locations on state highways in Oregon.  The ranking is known as the Safety Priority Index System, or SPIS.
The SPIS is a method of identifying locations where safety funds may be spent to provide the highest benefit. The SPIS is prioritized based on three years of crash data and considers crash frequency, crash rate and crash severity.
 To learn more about SPIS, visit the website:

Project Need
The intersections of U.S. 20 and Granger Avenue and U.S. 20 at Independence Highway have experienced a number of vehicle crashes higher or more severe than the state average for several years.  Most of these crashes are related to turning movements at the intersections.
At the Granger Avenue intersection, there have been 41 crashes recorded in the past five years.  Many were vehicles turning left from Granger Avenue onto U.S. 20, moving across on-coming traffic (See Crash Diagram in Library).
At Independence Highway, there have been 23 crashes in the past five years.  Like at Granger Avenue, many were vehicles turning left from Independence Highway to U.S. 20, moving across on-coming traffic.
While there have been no fatalities in recent years, there have been several serious injury crashes.

Road Safety Audit
In an effort to understand more thoroughly why the crash rate is high at the intersections, ODOT is performing the U.S. 20 at Granger and Independence Road Safety Audit.
A Road Safety Audit (RSA) is a formal safety performance examination of an existing or future road or intersection by an independent, multidisciplinary team.  Our ten member RSA team will study the section of road and the two intersections from a variety of perspectives. The goal is to identify the root causes of the situation and then suggest actions.
Our team is comprised of representatives from ODOT Transportation Safety, ODOT Roadway, ODOT Maintenance, Benton County, a local citizen and an ODOT consultant.
The team will be independent and will consider all potential road users and their needs.
In addition, our stakeholder group includes representatives of ODOT, the cities of Corvallis and Albany, school districts, nearby businesses, Oregon State Police, OSU, and Benton County.
After the study is complete, a report on the findings will be issued and made public.  The RSA is an excellent tool to identify and mitigate safety concerns.  The final report will include proposed remedies to safety problems.

Field work on the U.S. 20 at Granger and Independence Road Safety Audit will take place March 19, 20 and 21, 2012.
A preliminary report on the findings and conclusions will be released March 21, 2012 and posted to this website.
Then, a contractor for ODOT, DKS and Associates, will prepare a formal report with proposed remedies.  This report will be made public in late April, 2012 and posted to this website.
