The Proven Alternative for Congested Intersections

It’s an unfortunate truth that congested intersections tend to become more congested over time—despite the traditional remedies available to transportation professionals. Additional turn lanes and signalization may relieve congestion for a while, but sooner or later adding another turn lane or through lane--or perhaps prohibiting some movement—may be needed. In some cases, the transition to a grade-separated interchange may seem like the only solution.

There is, however, another alternative, one that is increasingly attractive considering the property impacts and financial burdens tied to grade-separated interchanges. That’s the Continuous Flow Intersection (CFI)

CFI is an at-grade design that provides comparable levels of vehicular flow to grade-separated interchanges at a fraction of the cost—and dramatic, long-term improvements over conventional at-grade approaches.
