Beltline Units 3-4 Handout (pdf, 2.7 MB

The Interstate 5 at Randy Papé Beltline project is located in Lane County within the cities of Eugene and Springfield, at the intersection of Interstate 5, mile post 195.45 and Randy Papé Beltline (OR 569). The phased project will correct deficiencies to enable the interchange to safely accommodate travel demands 20 years into the future. The HB 2001 portion of the project is being accomplished by two separate projects: I-5 @ Beltline - Unit 3 and I-5 @ Beltline - Unit 4.

The modernization project was been divided into smaller sections (units) to make it easier to construct as funding became available. Unit 1 was completed in late 2009, and Unit 2 was completed in the Summer of 2011 using both federal and state funds. Units 5, 6 and 7 have been integrated within Units 3 and 4 for construction in 2013 and 2015 respectively using state funds from the Jobs and Transportation Act. Construction for Unit 3 is well underway, as is design for Unit 4. Unit 3 was awarded to K & E Excavating Inc. on January 30, 2013.

Improvements under construction in Unit 3 are:

  1. A new I-5 southbound to westbound Beltline off-ramp.
  2. A new I-5 southbound to eastbound Beltline off-ramp.
  3. A new westbound Beltline to southbound I-5 on-ramp.
  4. A new Beltline Bridge over I-5.
  5. And base construction and structures for a new multi-use path to connect south of the interchange to north of the interchange. Path is to open upon completion of Unit 4 in 2016.

The planned improvements being proposed for Unit 4 are:

  1. A new eastbound Beltline auxiliary lane from Coburg Road to southbound I-5 on ramp;
  2. A new southbound I-5 auxiliary lane from Beltline Hwy to I-105;
  3. A new eastbound Beltline to northbound I-5 on-ramp, including a structure over I-5
  4. A new Harlow Bridge (replacement)
  5. Final stages of the Multi Use path that will be partially constructed in Unit 3
  6. A soundwall south of Beltline and east of Coburg Road
  7. A soundwall west of I-5, south of Harlow Road and north of I-105
  8. Noise studies for the replacement of the Harlow Bridge and noise mitigation as warranted


The additional work to be done in Units 3 and 4 will continue to modernize the interchange, which serves interstate, regional, and local traffic to the surrounding residential and commercial centers. The units will continue to correct deficiencies to enable the interchange to safely accommodate travel demands 20 years into the future.

The interchange is located at the northern boundary of Oregon’s second largest metropolitan center. Originally constructed in 1968, where dairy farms and pastures once occupied much of the area, today the land is being developed for residential, retail commercial use, interstate traveler services and industrial centers providing regional employment. The once rural interchange cannot accommodate the increase in traffic, creating congestion, delays and safety problems.

Current Status

I-5 @ Beltline Unit 3 construction was completed in November, 2014.

At the request of elected state representatives, and in the spirit of the JTA's emphasis on Practical Design, ODOT conducted a Value Engineering study of Unit 4 to reevaluate the design elements for cost savings and reduced impacts on right of way and utilities. Traffic analysis following the Value Engineering study concludes that I-5/Beltline will have adequate capacity to handle projected traffic volumes without the need of an additional auxiliary lane on eastbound Beltline, and without one additional lane for the ramp from eastbound Beltline to southbound I-5. The new analysis also shows no need for an additional southbound auxiliary lane on I-5 from Beltline to I-105 and, therefore, the Harlow Bridge will not require lengthening (replacement) at this time. However, the west end of the bridge will be revised to allow for a southbound extension of the multi-use path. Additional subsidiary design elements associated with the southbound I-5 auxiliary lane will be affected by the elimination of auxiliary lanes as well, as is the project time line. Construction is programmed for 2016 and 2017, a delay of one year. To learn the results of the Value Engineering study, click here.
