Long Term Closures - July 2018

I-5 Dunsmuir to Mt ShastaDunsmuir Grade Project on I-5
Phase 1: Mt. Shasta to Dunsmuir Scales

Phase 1: The Dunsmuir Grade Project will repave with concrete a stretch of Interstate 5 beginning north of Mott Rd and ending just north of Lassen Lane, for approximately 5 miles. This is a complex project and one that requires diverting traffic.

Critical construction is taking place from Monday, July 9th through the end of August 2018, and for that purpose, the following traffic conditions are in place:

  • Dunsmuir Scales to Mt. Shasta - Northbound traffic is reduced to one lane from just south of SR 89 to just north of Lassen Lane. The Lane adjacent to the median is closed.
  • Mt. Shasta to Dunsmuir Scales - Southbound traffic has been crossed over to the Northbound lane adjacent to the median (the closed lane.)
  • Traffic from SR 89 going North may proceed to I-5 North via the onramp. This access is open.
  • Traffic from SR 89 going South, please note the ramp is closed. To access I-5 South motorists may first proceed to I-5 North via the onramp, take the Lake St. Exit and then return to I-5 South.
  • Traffic from I-5 South to SR 89, please note the ramp is closed. To access SR 89 from I-5 South motorists may first proceed on I-5 South, take the Mott Rd. Exit, return to I-5 North, and then take the SR 89 Exit.
  • Concurrently with the above traffic conditions, crews will be dismantling sections of Interstate 5 southbound.

Anticipated Delays:
Normally, we anticipate delays up to 30 minutes during regular hours and delays of at least 1 hour during peak hours (7AM – 9AM and 1PM – 6PM). We have noticed a larger number of vehicles on Tuesdays, Thursdays, and Sundays. Please note, conditions can change any time due to a number of factors and/or unforeseen incidents.



Klamath River Bridge

Shasta Viaduct


The Shasta Viaduct Project, currently under temporary suspension, will replace a bridge that has ended its usable life. This structure is unique. By the end of 2017, a 1 ½ inch lateral deflection (movement) at the crown of the arches was observed during construction. On January 5, 2018 Caltrans stopped all operations at the site to conduct a design review. Currently, Caltrans is beginning preparations to continue and complete this project. We’ll update when construction resumes in full.
