the four-lane pronunciation
/thuh FOR-layn/
Meaning
Local talk for the wide road with two lanes each way. Locals often know which road is the four-lane without saying a route number. You take it to town when you want to move faster than the old blacktop. Not always an interstate. Any divided four-lane highway can wear the name in county talk.
How folks use it
- “We'll take the four-lane. The old road's full of curves.”
- “That new Dollar General sits right on the four-lane.”
Origin and etymology
Caught on in the mid-1900s as divided highways replaced skinny two-lane roads across the rural South and Appalachia. People named the road by how many lanes it had, not by the official highway number. Still how a lot of small-town directions get given.
Frequently asked questions
Is the four-lane always an interstate?
No. It can be a state highway or any divided road with four lanes. The interstate is the federal system. The four-lane is whatever big road your county means by that.
