Caltrans warned motorists today to expect hour long delays Memorial Day on Interstate 5 between Mount Shasta south to Anderson due to major freeway projects in progress.

According to the Caltrans District 2 Traffic Management Center in Redding, which monitors and gathers highway traffic data, the highest traffic volume period on the I-5 Corridor will be on Monday, May 25 between the hours of 11 a.m. and 8 p.m.

Three major projects on this stretch of I-5 involve lane closures, temporary concrete railing, speed limit reductions, as well as cone-and-barricade delineated construction zones.

These include bridge replacement at Sims Rd. and Crag View Dr., south of Dunsmuir; bridge deck and rail work at O’Brien Rd. located approximately 18 miles north of Redding in Shasta County; and the Redding to Anderson Six Lane Expansion Project also in Shasta County, Caltrans reported.

Measured traffic volumes on I-5 and other California State Routes have decreased after social distancing and stay at home mandates due to COVID-19 and travel experts suggest fewer people will hit the road during the upcoming summer holidays, Caltrans said.

The Caltrans District 2 Traffic Management Center in Redding also anticipates a lesser number of vehicles on I-5 and elsewhere during Memorial weekend.

However, traffic flow is not only directly influenced by the number of cars and lane closure constraints, but also due to accidents, extreme weather, and unforeseen situations, Caltrans explained.

Currently, traffic is reduced to one lane at the O’Brien, Sims, and Crag View bridges, located on I-5 between Mount Shasta City and Redding. If travel is necessary, Caltrans encourages southbound motorists are to travel at other times.

Southbound traffic is anticipated to experience up to one-hour delays and backups of up to four miles approaching Sims and Crag View Project south of Dunsmuir and the O’Brien Deck and Rail Project in northern Shasta County between the hours of 11 a.m. and 8 p.m. South of Redding, the traveling public will encounter the RASL, which currently has no delays anticipated.

Northbound traffic is anticipated to have no delays or backups at any of the construction zones on May 25, Caltrans said. The contractors for the above-mentioned projects, J.F. Shea Construction and Tullis Incorporated, may have people working over the holiday but this will not disrupt traffic.

Traffic delays in either direction at any of the work locations are not anticipated for Friday, May 22, Saturday, May 23, and Sunday, May 24.

One caveat: Caltrans District 2 reminded the public that traffic conditions may change at any time due to accidents or extreme weather.

Highway safety

Caltrans asked the traveling public to slow down throughout the construction zones, clearly delineated by temporary concrete rail, cones, and barricades.

The speed limit on I-5 in the North State, normally at 65 or 70 miles per hour, has been reduced to 55 miles per hour throughout construction zones. In many cases, the speed limit has been reduced to 50 miles per hour or less, Caltrans noted.

Fines are doubled in construction zones. California Highway Patrol Officers will be in the area.

“We recommend families and individuals, especially those traveling with children and/or pets, to bring enough food, snacks and water in case of lengthy delays,” Caltrans said in a press release asking for patience and understanding about possible delays.
