What is a Frontage Roadway Interchange?

A Frontage Roadway Interchange refers to roadways that run parallel to an expressway. These parallel roads serve a variety of purposes, including providing access to businesses, residential areas, and other facilities that are adjacent to the expressway. By allowing local traffic to flow without merging into the high-speed expressway, frontage roadways can help manage traffic congestion and improve safety by separating local traffic from expressway traffic.

This design helps facilitate smoother transitions for vehicles entering or exiting the expressway, as well as better accessibility for properties located near the expressway. It enhances the overall functionality of transportation infrastructure, enabling efficient movement of both local and expressway traffic without causing disruptions. Understanding the concept of frontage roadways is crucial for navigating interchanges successfully and recognizing how different types of roads interact with major highways.
