The U.S. 97: U.S. 26 Junction to NW 10th Street project was 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 was a critical part of the State’s transportation system and is the main north-south transportation corridor through Central Oregon. This project aimed to improve the overall safety and mobility for the freight industry and travelers on the east side of the Cascade Mountain Range.
Project components included:
- 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 was 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 former asphalt within the project limits had reached its design life and was quickly deteriorating with severe potholing and rutting causing safety and operational issues. These problems needed to be addressed in order to minimize further deteriorating pavement structure condition. Dense cracking and rutting was also a problem on the Crooked River Gorge Bridge. A major rehab of the bridge deck was needed to prevent further deterioration and avoid possible mobility impacts.
