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 guardrail on I-5 from the California border to south of Ashland.


Traffic Impact

Expect slow moving traffic with resulting delays in the work zone. Northbound Exit 6 off-ramp is closed due to adjacent bridge construction. Interstate traffic will experience single-lane traffic separated by a concrete barrier. 

The construction speed limit is 40 MPH.

Northbound Exit 6 traffic may use either Exit 1 to travel north on Old Siskiyou Highway (Oregon 273) to access Callahans or the Mt. Ashland Ski Road or travel to either Ashland Exit 11 or Exit 14 to return southbound to Exit 6.

ODOT is using Smart Work Zone real-time Bluetooth technology to record travel times through the work zone. Visit

Construction Impacts

Expect single lane traffic in the southbound lanes from MP 6.5 to the summit at MP 4.5. The contractor is currently rebuilding the northbound Exit 6 bridge deck through the summer. Expected date of opening is mid-August.

​The undercrossing on Old Siskiyou Highway is open under flagger control when the contractor is working. Otherwise, it is open to traffic. 

Closures in place include the northbound off-ramp and for now, the northbound on-ramp.

​Monitor changing work zone travel times at (Look for the watch icon).

Meetings and Events

Due to the ongoing public health emergency, residents along Old Siskiyou Highway and the Mt. Ashland Ski Road have been mailed notices directly of the project impacts.


This year and next (2021), the contractor will be back on the interstate by mid-April, weather-permitting.



​We're maintaining the roadway, bridges and other highway safety features for the future.

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.  Since it's in a snow zone, much of the roadway surface is damaged and rutted by chains and studded tires.

This project improves the condition of the 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.

Some concrete roadway sections are in such poor condition they will be rebuilt. Year one rebuilt the southbound slow lane from MP 11.4 to 9. Year two will rebuild the southbound slow lane between MP 6.5 to 9 as well as replace the northbound Exit 6 bridge deck.
The project also includes: removal of steel I-beam bridge expansion joints and repair of joints and any exposed steel rebar.

The project also repaves 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)​​​
