I-5: California Stateline to Ashland Paving

Construction Phase

Region 3: Southwestern Oregon (Ashland, Jackson)

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​This project repairs and upgrades the concrete roadway, bridges and guardrails on I-5 from the California border to south of Ashland.


Traffic Impact

Contractor is back in the project area. Look for first lane closures to begin Monday, May 8 to correct Exit 6 bridge deck issues and apply final striping in the project area.​

Construction Impacts

Expect construction in the project area early this summer.

Corrective work is needed on the protective covering of the southbound and northbound bridge decks at Exit 6 over Old Siskiyou Highway.

Beginning June 8, watch for single lane traffic southbound at the Exit 6 bridge for corrective deck seal repairs. Southbound on-ramp will also close for this work.  Follow detours on Old Siskiyou Hwy to Exit 1 southbound. 

Contractor will switch to Exit 6 northbound off-ramp closure for about the same duration in June.   

​Other finish work includes barrier and drain repair and then final permanent striping in the project area.


Holdover to spring/early summer 2023

  • Corrective work on north/southbound bridge deck seal 
  • Final striping, recessed pavement markers
  • Other incidental repairs​

Items completed this construction season, 2022:

  • Installed 6 variable message/speed signs 
  • Rebuilt southbound slow lane concrete MP 9-8 
  • Completed paving shoulders
  • Inlet and drain adjustments
  • ​Exit 1 bridge deck rehabilitation and on and off ramp paving



​We're maintaining the roadway, bridges and other highway safety features for the future generations and to keep our economy moving forward.


I-5 | ​Interstate 5 from the border with California to just south of Ashland (MP 0 to 11.45)

Cost and Funding

​$32 million.


​Carter and Company of Salem


​This project rehabilitates and rebuilds the concrete road surface, which is rutted and in poor condition.  We've also added work to this contractor for new permanent message and variable speed limit signs for Siskiyou Summit.

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're in year three of the project. Much of this year's visible work is 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)​​​
