Diamond Lake Boulevard/OR 138E Design Concept Plan

The City of Roseburg and the Oregon Department of Transportation (ODOT) are planning improvements to Diamond Lake Boulevard/OR 138E to provide safer and more convenient travel options along the corridor. With new housing and future growth planned along OR 138E, ODOT and the City are taking action now to design improvements so the corridor better serves all of Roseburg’s residents and visitors, including people walking, biking, rolling and driving.

Upcoming Events and Opportunities

Focus Groups and Subcommittees

ODOT seeks community representatives who reside, work or travel in the study area to participate in two focus group-style subcommittees (identified below) to identify transportation barriers and future opportunities. You may qualify for a financial stipend for your volunteer participation.

  • Youth, seniors or people with disabilities, low-income and working families, people of an ethnic or racial minority: Intended for people who live along and rely on the corridor for their primary transportation needs.
  • Business owners, property owners, developers: Intended for people who own property or a business within the study area.

Please contact Thomas Guevara Jr., ODOT Senior Transportation Planner/Agency Project Manager at 541-957-3692 or thomas.guevara@odot.oregon.gov for more information and required forms to see if you qualify for a stipend through ODOT’s Equitable Engagement Compensation Program (EECP).

The Plan’s Purpose and Benefits

We’re creating an actionable plan to better serve the people who live, visit and travel along the OR 138E corridor. The Plan will:

  • Identify safety and mobility improvements for the 3.5-mile stretch of Diamond Lake Boulevard, including the highway, connecting routes and parallel roadways
  • Create a blueprint for planning future growth consistent with safe and reliable travel options for the corridor’s residents
  • Provide safe, comfortable, and accessible travel options for people who walk, bike, roll and drive along the corridor to downtown Roseburg and other areas
  • Improve connections to popular destinations and paths, such as the Umpqua River Trail

Project Area

The project area along Diamond Lake Boulevard/OR 138E stretches from SE Douglas Avenue east to Roseburg’s eastern urban growth boundary (UGB) near Sunshine Park.

Note: Diamond Lake Boulevard becomes North Umpqua Highway east of NE Patterson Street; both “Diamond Lake Boulevard” and “North Umpqua Highway” refer to OR 138E.
