What is the best highway interchange?
The stack interchange, sometimes known as a butterfly interchange, is arguably the most efficient interchange design in the world.

As verbs the difference between overpass and interchange is that overpass is to pass above something, as when flying or moving on a higher road while interchange is to switch (each of two things).
What is a turbine interchange?
The turbine interchange (also known as a whirlpool) is an alternative four-way directional interchange. The turbine interchange requires fewer levels (usually two or three) while retaining directional ramps throughout.
How many four-level stack interchanges are there in Canada?
Although it planned to build many four-level stack interchanges, Canada has only one true four-level stack interchange, between Highway 400 and Highway 407 in Ontario.
Where was the first stack interchange in North America?
North America. The first stack interchange was the Four Level Interchange (renamed the Bill Keene Memorial Interchange), built in Los Angeles, California, and completed in 1949, at the junction of US Route 101 (US 101) and State Route 110 (SR 110).
Where are the stack interchanges in the Baltimore area?
Another four-level stack interchange in the Baltimore area is located at the northeastern junction between I-695 and I-95. The stack was built as part of a massive I-95 reconstruction project that includes high-occupancy toll lanes (HOT lanes), designed to relieve congestion between Baltimore and its northeastern suburbs.
What are the characteristics of a modern highway interchange?
Most highway interchanges are now designed with no left-hand ramps, no weaving sections, proper lane balance, enough space between ramps, no sharp turns, and acceleration and deceleration lanes on the ramps. The second photo is an aerial view of an old-style interchange that violated these rules.
