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

Expect single lane traffic now through mid-October, 2021 in various locations of the work zone. This includes near the Mt. Ashland Exit 6 area as contractor replaces the southbound bridge deck.
ODOT is using Smart Work Zone real-time Bluetooth technology to record travel times through the work zone. Visit

Construction Impacts

​Exit 6  ramps are open. The southbound off-ramp is modified but open to all traffic (see graphic below).

Here's this season's lane closure:

  • Now thorugh mid-October, new concrete deck replacement on the southbound bridge over Old Siskiyou Highway near the Mt. Ashland Exit 6.
  • Now through mid-August: Expect night closures only for deck repairs and new protective overlay, new rail fencing on the Exit 1 and 11 bridges.

Between now and mid-October, concrete roadway repairs and replacement will also occur in the 11-mile work zone. Speed limit in the work zone will be posted at 40 mph.

​​​What else are we doing this year?  

  • Continue paving of ramps, shoulders and installation of new guardrail
  • Continue work repairing the concrete pavement​


​Between now and mid-October, concrete roadway repairs and replacement will also occur in the 11-mile work zone. Speed limit in the work zone will be posted at 40 mph.​

There have been some COVID-related scheduling delays from last year and work has been added for new electronic message boards. 



​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

​$30.7 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)​​​
