a broad highway designed for high-speed traffic
"We took the expressway to cut across town and reach the airport before our flight left."
A divided highway where intersections and direct access to adjacent properties have been eliminated.
"The traffic moved smoothly along the expressway because there were no side streets or driveways, only on- and off-ramps for entering and exiting."
The word comes from combining the words "express" and "way." It originally referred to a road designed for rapid travel without stops.
