Traveling I-5? Traffic Could Get Ugly…

Caltrans District CTPress release from Caltrans:

The California Department of Transportation (Caltrans) District 2 advises the traveling public about a potential increase in traffic on Interstate 5 (Shasta and Siskiyou Counties) this weekend due to the following factors:

  • A Pacific Crest Trail event in Mt Shasta,

  • The restrictions resulting from current highway construction from Dunsmuir through Mt Shasta,

  • The high traveling season,

  • An ongoing increase of large commercial vehicles.

On Friday, July 20, motorists may see an increase of I-5 northbound traffic as people from other parts of California are expected to travel to Mt Shasta for a full-day event to be held on Saturday, July 21. Mt. Shasta will be celebrating its status as the first ever Pacific Crest Trail Town and that may draw many visitors. Consequently, on Sunday, July 22, motorists may see an increase on I-5 southbound traffic as people may be returning home.

Meanwhile, the Dunsmuir Grade Project on I-5 is undergoing critical construction which includes lane closures, detours and no alternative routes. Traffic delays are anticipated on weekends from 30 minutes to 1 hour. Critical construction is scheduled from July 9th through end of August. A lane will be reopened after that and the project continues until its anticipated completion in 2020, for a total of 2 years of construction.

The traveling public is advised to add extra time to their trip, be patient, and have water and snacks especially if traveling with children.

    Traffic is ugly on I-5 EVERY DAY!

  • I traveled I5 recently, hadn’t been on that road since I retired several years ago. It used to be a rule of thumb that trucks had one mile to pass and then would be cited. Not anymore, now they spend 5 miles in the left lane to pass a truck that’s going 3mph slower. This should not be permitted ……
