I-5: Coburg Interchange
Overview

 

Located on Interstate 5, mile points 198.39 to 200.15, adjacent to the City of Coburg, the interchange will undergo physical improvements. The project’s purpose is to improve safety and efficiency of travel on Coburg Industrial Way, Roberts Road, Pearl Street and Interstate 5 by:

  • Realigning the local road network on the south side of Pearl Street.
  • Improving Pearl Street from the ramp terminals to Coburg Industrial Way.
  • Implementing interchange access control and spacing standards on the west side of I-5, as depicted in the Interchange Area Management Plan (IAMP). 
 
Specifically, the project will;
  • Close access to Roberts Road on the south side of Pearl Street with a cul de sac.
  • Connect Roberts Road to the intersection of Coburg Industrial Way and Pearl Street by constructing a new road, Coburg Industrial Way South.
  • Widen and lengthen the I-5 southbound on-ramp to accept 2 lanes turning east to south from Pearl Street.
  • Add a free flowing slip lane for a right turn north to Coburg Industrial Way from westbound Pearl Street.
  • Add water quality facilities to allow for drainage and water treatment for run-off from the new impervious surfaces as well as existing roadway surfaces.

Construction Information

Wildish Construction of Eugene was awarded the low-bid contract for $2.234 Million.  Construction will begin in summer of 2012 and complete in 2013.

 
Future Needs
Based on the best available transportation forecasts, the need for several additional improvements to the Coburg interchange over the next 20 years has been identified in the Coburg Transportation System Plan (TSP) and ODOT’s Interchange Area Management Plan (IAMP).
 
A complete replacement of the interchange bridge over I-5 and further modifications to the interchange ramps have also been identified as future needs to safely and efficiently serve the travel demand that results from population and employment growth in the Coburg area that is anticipated over the next 20 years.

While the need for these improvements is identified in the current Coburg TSP and the IAMP, funding for these projects is not available at this time and there is no specific time frame or expectation for their construction. The need for these improvements will also be re-evaluated through the analysis being conducted to support the update to the Coburg TSP. Now underway, this TSP update process is expected to take about 19 months to complete. The IAMP may also be modified as a result of the TSP update.

 
Current Status
The project currently has $14.6 million in funding, including $12 million in federal earmarks, and the rest in Statewide Transportation Improvement Program funding. Negotiations regarding local matching funds, intergovernmental agreements and permit approvals are ongoing with Lane County. 
  
 
Public Involvement
No meetings are scheduled at this time. Opportunities for public input will be available during Coburg’s Transportation System Plan update.
