Cost and Funding

​Estimated at $25.7 million.

​This project rehabilitates and rebuilds the concrete road surface, which is rutted and in poor condition.

What Problem Will This Improve?

The concrete pavement is in poor condition. Much of the roadway surface is damaged and rutted by chains and studded tires since it is in a snow zone.

This project improves the condition of the concrete pavement by using a one-half inch concrete grind to remove roadway ruts. This grinding method is similar to using rough sandpaper to profile a piece of wood.

Concrete roadway sections in poor condition will be rebuilt. 
We'll be in year three of the project when it begin again in April 2021. Much of this year's work is take up with constructing the new Exit 6 southbound bridge deck.

The project will repave asphalt shoulders and exit ramps and replaces guardrail within the project limits.

Affected bridges are:
  • OR 273 bridge over I-5 MP 0.95 (Exit 1 overpass)
  • I-5 Bridges at MP 4.63 (near Siskiyou Summit) over OR 273
  • I-5 Bridges at Exit 6 (Old Siskiyou Hwy, Mt. Ashland, Callahan’s, Upper Shed Exit)
  • I-5 Bridge over OR 99- MP 11.89 (Ashland Exit 11 NB directional exit)​​​
