OR 217 Interchange Management Study
Study overview
The objective of the OR 217 Interchange Management Study is to identify and evaluate the types of lower cost, fundable projects that could feasibly be constructed for OR 217 today to increase reliability, mobility, and safety, primarily between U.S. 26 and Greenburg Road.  This is a partnership study with ODOT, City of Beaverton, City of Tigard, Washington County, Metro, and the State and Federal Government.  To date, two phases of the study have been completed. 
 
OR 217 connects I-5 and U.S. 26, and is approximately seven miles in length. It is the primary access for two regional centers and a town center (Washington Square Regional Center, Beaverton Regional Center, and Tigard Town Center) and carries up to 120,000 vehicles per day, yet the facility is one of the least reliable freeways in the Portland Region
 
Along OR 217 there are numerous safety and mobility problems, including recurring bottlenecks, high crash rates, and unreliable travel times. Factors that lead to these problems include morning and evening peak period demand that exceeds capacity, lack of shoulders, and short weaving areas that create erratic changes to traffic speeds due to interchange spacing. Several interchanges are less than ¼-mile apart, which does not allow adequate space for the weaving that occurs between entering and exiting vehicles. There are approximately 200 crashes a year along OR 217, which equates to a crash occurring four out of every five weekdays.
 
A previous study addressed these mobility and safety problems with costly capital projects such as widening to six lanes, braiding ramps, and adding collector-distributor roadways.   These high-cost improvements total nearly $1 billion for the corridor, and are generally over $100 million at key interchanges. Given existing and forecasted funding levels, these projects are not likely to be funded in the foreseeable future.
 
This approach is consistent with ODOT’s goal to improve transportation operations by first addressing management techniques prior to building additional capacity to a highway.
