The California Department of Transportation (Caltrans) is considering a high-speed bus system that could travel between San Francisco and Los Angeles at speeds up to 140 mph.
This proposal aims to provide an alternative to high-speed rail and address California’s traffic issues. According to KQED, Caltrans envisions buses operating on dedicated lanes along state freeways, potentially cutting travel time between the two cities to as little as three hours.
The concept is still in the research phase, with significant engineering challenges to overcome, such as designing dedicated lanes and enhancing bus safety features. Men’s Journal reports that the buses could operate on interstates 80, 5, and U.S. Route 101, connecting major cities like San Diego, Los Angeles, and San Francisco. The project draws inspiration from Adelaide, Australia’s O-Bahn guided busway, though the speeds proposed by Caltrans are significantly higher.
Caltrans’ feasibility studies manager, Ryan Snyder, highlighted that the high-speed buses could complement the high-speed rail currently under construction, adding value to the rail network by connecting it with other regions. However, the project faces hurdles, including the need for infrastructure upgrades and the development of advanced bus technologies.
Planetizen notes that the buses would require high-speed-rated tires, multiple redundant braking systems, and advanced aerodynamics to ensure safe operation. The proposal is awaiting funding and further research to determine its feasibility and potential impact on California’s transportation landscape.
