Express lanes projects benefit all drivers on the highway. By moving more vehicles at more efficient rates on the express lanes, the conditions on the general purpose lanes also improve, providing greater mobility on the highway, including commercial vehicles. After the completion of the 95 Express project in Miami-Dade County, the average speed on the general purpose lanes increased from 20 m.p.h. to 40 m.p.h. during peak hours.
The speed improvements on the general purpose lanes result in significantly reduced traffic congestion proving that express lanes benefit all drivers on the highway. Additionally, the express lanes are provided as an option for drivers who choose to pay for using the lanes. However, commuters who do not choose to use the express lanes still receive a significant benefit in the form of increased incident management resources, as well as improved travel speeds and reduced traffic congestion on the toll-free lanes.
