Why is "California State Route 299" trending?

Wikipedia Overview

State Route 299 is an east–west state highway in the U.S. state of California that runs across the northern part of the state. At 305.777 miles (492.100 km), it is the third longest California state route, after Route 1 and Route 99, and the longest east-west route. Route 299's western terminus is at US 101 at the northern edge of Arcata, and its eastern terminus is at the Nevada state line at a point east of Cedarville. Between Arcata and Redding, Route 299 intersects with State Route 96, and is briefly co-signed with State Route 3. In Redding, it intersects with State Route 273, State Route 44, and Interstate 5. East of Redding, it intersects with State Route 89, and a section is co-signed with State Route 139 before reaching Alturas. It is then co-signed with U.S. 395 northeast of Alturas, and then runs east through Cedarville and to the border with Nevada. The ghost town of Vya, Nevada can be reached via this route which, after the border, becomes a dirt road that formerly served as Nevada State Route 8A. The segment of SR 299 between Arcata and Redding is the Trinity Scenic Byway, a National Forest Scenic Byway.
