Reminds me of the town line between Northbridge, MA and Sutton MA.

There's a bridge over a major highway right on the border of the two towns. The highway supers hate each other, and neither ever took responsibility for their crews plowing the bridge.

Most big snowstorms there would be a berm in the middle of the bridge where the plows from each town would turn around. Neither town would plow the whole bridge.

Made the commute miserable, but it's a funny little quirk of small town New England.
