The U.S. 97: U.S. 26 Junction to NW 10th Street project is located along The Dalles-California Highway in Jefferson County. The purpose of this project is to repave 12 miles of U.S. 97 from Ford Lane just south of Madras (101.2) to NW 10th Street in Terrebonne (MP 113.6). U.S. 97 is a critical part of the State’s transportation system and is the main north-south transportation corridor through Central Oregon. This project aims to improve the overall safety and mobility for the freight industry and travelers on the east side of the Cascade Mountain Range.
Project components include:
- Repaving of U.S. 97 between NW 10th Street two miles north of Terrebonne and Ford Lane four miles south of Madras.
- Improvements to the Crooked River Gorge Bridge .
- Add or replace durable striping, rumble strips, and recessed pavement markers.
- Safety improvements of the intersection of U.S. 97 and the U.S. 26 Madras/Prineville Highway Junction.

Cost and Funding
Cost includes roughly $250,000 for project development and $5.8 million in construction.
The 2015 annual average daily traffic (AADT) ranges from 9,100 to 13,800 vehicles per day with trucks accounting for 25.5% of traffic. Between 2013 and 2015 there were a reported 116 crashes on this stretch of highway of which four were fatal or resulted in serious injury. The primary benefit of this project is to reduce fatal and serious intersection crashes by improving this section of highway. Safety upgrades like intersection upgrades and rumble strips have been shown to decrease crashes by aiding in a driver’s awareness.
The existing asphalt within the project limits has reached its design life and has quickly deteriorated with severe potholing and rutting causing safety and operational issues. These problems need to be addressed in order to minimize further deteriorating pavement structure condition. Dense cracking and rutting is also a problem on the Crooked River Gorge Bridge. A major rehab of this bridge deck is needed to prevent further deterioration and avoid possible mobility impacts.
