Tollabout

Tollabout is a term used to describe a type of toll road in the United States, particularly in the state of California. These roads are characterized by their unique tolling system, which is often referred to as a "tollabout" system. The term "tollabout" is a portmanteau of "toll" and "about," reflecting the fact that drivers are charged a toll only when they are traveling on the toll road, and not when they are traveling on the adjacent non-tolled road.

The tollabout system was introduced in California in the 1990s as a way to reduce congestion on major highways. The system allows drivers to use the toll road for free if they are traveling at a certain speed, typically 45 miles per hour or higher. If a driver's speed drops below this threshold, a toll is automatically charged. The toll amount varies depending on the length of time the driver was traveling below the speed limit.

The tollabout system has been implemented on several major highways in California, including the San Diego Freeway (I-805) and the San Francisco Bay Bridge. The system has been generally well-received by drivers, as it provides a way to avoid congestion without having to pay a toll. However, some critics have argued that the system can be confusing and difficult to understand, and that it can lead to increased traffic on the adjacent non-tolled road.

Overall, the tollabout system is a unique and innovative approach to tolling that has been used in California to help reduce congestion on major highways. While the system has its critics, it has also been praised for its ability to provide a more flexible and convenient way for drivers to avoid tolls.
