"Caltrans Provides Bleak Topanga Canyon Update"

Caltrans expects a section of Topanga Canyon Boulevard to remain closed until fall due to a massive landslide that occurred during a rainstorm in March, with 9.2 million pounds of earth blocking the road. The unstable hillside poses a safety risk, and clearing the slide is challenging due to ongoing water seepage and the risk of further earth movement. Drivers are advised to use alternate routes, and the public can submit questions to Caltrans regarding the closure.

"Persistent Threat: Big Sur's Ongoing Battle with Highway 1 Collapses"

The closure of a stretch of Highway 1 in Big Sur due to erosion has left communities in uncertainty, as Caltrans works on a temporary fix to allow limited access. The area's geology, prone to rockslides and erosion, makes the road vulnerable to frequent closures and repairs. Engineers are assessing the damage and stabilizing the road, with a temporary traffic signal planned for more regular traffic. However, a permanent fix may take months, as Caltrans grapples with the challenging terrain and the need to keep the road stable.

"Big Sur Tourism Grinds to a Halt as Coastal Roadway Collapses Again"

A portion of Highway 1 in Big Sur collapsed into the sea, leaving tourists and locals stranded and forcing about 1,600 people to seek accommodations for the night. Caltrans deemed the northbound lane safe enough to travel and began escorting people out in caravans. The closure has put Big Sur tourism on standstill, with only essential workers and residents allowed through, and officials are planning to install a concrete barrier down the center line of the road to create an isolated channel for motorists. The closure is expected to last at least two weeks, and officials are hopeful for a sooner reopening.

Fire-Damaged 10 Freeway Disrupts Los Angeles Traffic and Immigrant Businesses

Immigrant businesses operating underneath the 10 Freeway in Los Angeles, rented from a Calabasas businessman who illegally sublet the spaces at higher rates, were devastated by a recent fire that caused severe damage to the freeway. The landlord, Apex, owned by Ahmad Anthony Nowaid, had failed to pay rent on the property and owed $78,000 to Caltrans. Nowaid's firm had secured leases for government-owned property with restrictions, but illegally sublet them to various businesses. Many of the businesses did not have insurance and lost all their inventory and equipment. The relationship between Nowaid and his tenants had soured, with tenants stopping rent payments after Caltrans planned to evict Apex. The cause of the fire is believed to be arson.

Crash Testing Truck Attenuators: Unveiling the Science Behind Safety

The California Department of Transportation (Caltrans) conducted crash tests on truck-mounted attenuators in the early 1980s using their own designs based on Hexcell aluminum honeycomb. The tests involved crashing 18 cars and one dump truck into the attenuators, with the best design featuring increasingly larger blocks of Hexcell. Despite the DIY approach, the attenuators performed well, keeping impact velocities below 27 mph (43 km/h). These crash tests contributed to the development of safer highway work zones and improved survivability in motor vehicle accidents.
