The Beltline Highway is located in Lane County and is functionally obsolete and cannot handle current and future traffic volumes. Following analysis, ramp meters were recommended at four locations to alleviate congestion and to improve safety on the Beltline Highway corridor through Intelligent Transportation Systems (ITS). ITS makes use of advanced communication and computer technology to improve the operation of a facility and enhance the movement of people and goods.

The project was to analyze, design, and construct ITS solutions along the Beltline Highway corridor where it could be adapted to work with a minimum of infrastructure changes and disruptions. ODOT, in collaboration with the City of Eugene and Lane County advanced the planning study recommendation of placing ramp metering at eastbound Beltline Hwy River Road and River Avenue on-ramps, and at Beltline Hwy westbound from Green Acres and Coburg Roads on-ramps. Ramp metering from northbound Delta Highway to westbound Beltline was not included due to the lack of adequate ramp length for que storage.

The ramp designs were completed in the fall of 2012 and the project work was awarded to Lantz Electric Inc. of Eugene. Construction was completed at the four recommended locations in June of 2013. A ramp meter is a traffic signal on a ramp that controls the rate vehicles enter a freeway facility. Kittelson and Associates Inc., under a separate contract, ha conducted performance evaluations of the four ramp meter locations to determine how effective they are at reducing congestion and improving safety. Since the activation of the meters, ODOT has worked through and solved unexpected challenges with the systems adaptive software. There has been a notable reduction in crashes with a 35% decrease from 2013 data.


The Beltline Highway (OR 569) carries the majority of traffic crossing the Willamette River and connecting western Lane County to Interstate 5. Traffic moving onto and off of Beltline Highway between River Road and Coburg Road is slow and congested during busy travel times. A planning study was conducted to assess deficiencies on Beltline Highway between River Road and Coburg Road and recommended long-term solutions. The complete list of new infrastructure to address deficiencies will take several years to develop and fund.The Delta interchange is functionally obsolete and cannot handle current and future traffic volumes. Its intersection with Beltline Highway is a chokepoint in the daily operation of both facilities and is a safety priority site. Improvements at the interchange include an expanded northbound Delta to westbound Beltline on-ramp along with other interchange improvements that will improve the capacity and operation of the facilities. Traffic models indicate that if the ramp from northbound Delta to westbound Beltline could be metered, it would improve travel time savings through the corridor.

Current Status

The existing ramp meter system will continue to be monitored and its operation refined, including working with the City of Eugene on the River Road signal timing to ensure performance. Real time travel data is continually collected to evaluate adaptive system performance. We are moving toward construction of a project at Beltline at Delta Interchange outlined in the Beltline Facility Plan. The Oregon Transportation Commission has approved funding of $2.5 million for preliminary engineering for the interchange design. The plan is to add a new structure on Delta Highway, reconfigure on and off ramps to and from Beltline, and add ramp metering. Another JTA project, the Beltline Interchange Unit 4 at Interstate 5, is in its last phase of construction and was re-engineered to have fewer project impacts and a reduced budget. The realized cost savings will re-programmed to address the Delta Interchange improvements. Beltline/Delta Interchange construction is anticipated in 2018.
