**An ODOT contractor will perform tree and brush removal in February and March 2012, to prepare the interchange area for major construction. As part of the final work on the U.S. 26: Glencoe Road Interchange Project, ODOT will re-plant the area densenly with native riparian trees and shrubs, and wetland species.
**The community has voted on three retaining wall treatments and the winner is...Oregon Basalt! See the Retaining Wall section below for more information.

| Project Overview |
|
ODOT (along with the City of North Plains and Washington County) previously developed a draft Interchange Area Management Plan (IAMP) for the U.S. 26/Glencoe Road interchange, which identified $80 to $90 million of interchange improvements.
The 2009 Oregon Legislature allocated $32 million in the Jobs and Transportation Act (JTA) to fund improvements to the interchange. ODOT is working with the city and county to develop a design concept that meets the $32 million budget provided. The project will prioritize safety and mobility improvements and strive to increase capacity for the most critical movements.
Project Elements:
- Replacing the Glencoe Road bridge over U.S. 26 with a new, four-lane bridge (the bridge will be built wide enough to accommodate five lanes in the future)
- Lengthening and widening the U.S. 26 westbound exit ramp
- Replacing the culvert on Glencoe Road to the north of the interchange with a new structure
- Improving pedestrian and bicycle connections on the new bridge over U.S. 26
- Improving intersection components, including traffic signals, signing, striping, drainage and water quality
Glencoe Interchange
The existing two-lane Glencoe Road over-crossing lacks adequate shoulders, turn lanes, and bicycle/pedestrian accommodations. The most significant safety issue is that the existing westbound off-ramp is not long enough to safely accommodate vehicles using the interchange, creating backups onto U.S. 26.
In addition, the interchange cannot support the projected increase in traffic volumes, both from the adjacent City of North Plains and the larger regional vicinity, which includes the Cities of Hillsboro, Cornelius, and Forest Grove. The interchange is an important access point from U.S. 26 to these cities. The U.S. 26/Glencoe Road interchange modernization project is intendend to support economic development and mobility in the region. This project is needed to support present and planned land use and industrial development in western Washington County.

| Retaining Walls |
|
As part of the project, ODOT will construct a retaining wall (approximately 450 feet long) along the westbound U.S. 26 off-ramp and a smaller retaining wall (approximately 160 feet long) that will be part of a new tributary bridge. These walls will be visible from a proposed future city trail.
There are three options for architectural treatments for these retaining walls. We invited community members to vote for which treatment they would prefer. Voting is now closed and the retaining wall treatment that received the most community votes is Oregon Basalt. This architectural treatment will be incorporated into the design and construction of the Glencoe Road Interchange Project.

| Jobs and Transportation Act (JTA) |
|
The Oregon Jobs and Transportation Act (HB 2001) is the transportation funding plan approved by the 2009 Oregon Legislature. Three core themes emerged from the legislation:
- accountability, innovation and environmental stewardship;
- highway, road and street funding; and
- multimodal funding.
Additional provisions address important elements of Oregon's transportation system and our statewide economy.
The JTA identified 37 specific highway projects (plus funding for 12 local governments in eastern Oregon). These projects and allocations total $960.3 million. In ODOT Region 1 (Portland-Metro area), there are eight JTA projects, including the U.S. 26/Glencoe Road Interchange project.

| U.S. 26 Glencoe Road Interchange Area Management Plan |
|
The U.S. 26 Glencoe Road Interchange Area Management Plan (IAMP) has been developed in conjunction with the U.S. 26: Glencoe Road Interchange Jobs and Transportation Act Project. The purpose of the IAMP is to protect the long-term function and safety of the interchange, and to minimize the need for future major interchange improvements. It is required by law for any new or significantly reconstructed interchange (OAR 734-051-0155.6).
The Draft IAMP is now available for review and public comment. Please note that the file is large and may take several minutes to download. ODOT is scheduled to present the IAMP to the Oregon Transportation Commission in December 2010 for adoption.
