What does thruway mean?
Thruway is a chiefly American noun for a limited-access highway designed to carry long-distance traffic with restricted access and limited stopping. In general use it suggests a major, high-speed route that may be divided, grade-separated, or tolled; those details are not obligatory meanings of the word. Writers often choose freeway or expressway instead, but thruway is especially associated with the vocabulary of American road travel. It can function as a count noun, with thruways plural, and it appears naturally in phrases such as take the thruway or a thruway exit. The word is a clipped respelling of throughway, itself built from through and way, and the shortened form was already in circulation by the 1940s. Its history therefore reflects the early development of the modern controlled-access road, a type of infrastructure designed to move through traffic with fewer interruptions than conventional highways.
