About the Project

I-5 Exit 124 and Exit 125 Interchange Area Management Plan (IAMP)  and Garden Valley Corridor Plan 


We're working to establish a set of transportation solutions and land use/policy actions that will help to balance and manage transportation and land use challenges over time. 

Our efforts will result in two separate, but coordinated, plans:

  • ODOT Interchange Area Management Plan
  • City of Roseburg Garden Valley Corridor Plan (GVCP)

Together, these plans will guide future development and how the corridor can manage growth over time.

​A corridor plan is a planning project that studies the conditions of a major roadway, including the adjacent land uses and current and future conditions for vehicles, pedestrians, bicycles, and transit.​

​The basic purpose of an IAMP is to establish an agreement with a local government (or governments) about what, if any, transportation solutions or land use/policy actions are needed in an interchange area and how best to balance and manage transportation and land use issues over time. It is an important tool in protecting the function and operations of state highway interchanges and the supporting local street network.​​

Locations we're studying and why


Why this location?

  • High pedestrian activity near Roseburg High School (RHS).
  • Lack of bicycle connectivity; no facilities west of I-5.
  • Need to balance the needs of residential, commercial and freight users traveling through the interchange.
  • Traffic backs up during the beginning and end of the school day around RHS.
Constraints:
  • Limited acceleration and merging distances on the northbound loop on-ramp.
  • Limited sight distance & acceleration distance along southbound on-ramp.
  • Ramp terminals connect across from public streets (Bellows and RHS).
  • Bike/Ped crossing of free-flowing on-ramp
  • Closely spaced accesses/driveways within interchange influence area (26 private and 9 public access points).

Why this location?

  • Lack of bicycle facilities over I-5.
  • Traffic backs up at northbound ramp terminal, which is also a top 10% statewide crash site.
  • Need to continue to protect and facilitate access to important community destinations, including commercial and medical facilities.

Constraints:

  • Limited acceleration and merging distances on I-5 on the northbound loop on-ramp.
  • Limited sight distance and acceleration distance along the southbound on-ramp.
  • Ramp terminal connects directly across from public street (Mulholland Dr).
  • Bike/Ped crossing of free-flowing on-ramps.
  • Closely spaced accesses/ driveways within interchange influence area (24 private and 12 public access points).

The Garden Valley Corridor Plan (GVCP) will identify strategies for the City to improve safety, mobility and connectivity so the corridor better serves our community's needs now and into the future

Why this location?

  • Limited crossing opportunities for pedestrians, particularly east of I-5.
  • Uncomfortable environment for bicycles and pedestrians.
  • Long queues in westbound outer lane during evening commute.
  • Provides access to important community destinations (commercial, government and medical).
  • Prevalence of driveways/access points creates congestion and conflict points between vehicles, bicycles and pedestrians.
  • Congested “gateway" intersections with Stewart Pkwy and Stephens St.
  • History of top 5% and top 10% statewide crash sites.
  • RR crossing can cause long delays and block accesses when a train passes through.
  • Limited right-of-way east of I-5.
