There's a spot in Michigan's highway network that many (most!) drivers pass through without a second thought. Other drivers double take and even facepalm. The spot is on US 10 northwest of Clare where the road transitions from a two-lane highway to an expressway.

US 10 runs, in Michigan, from Ludington at the ferry dock to Bay City. The western half of the highway's run is that two-line highway. At Farwell, where the highway crosses M-115 it becomes an expressway from Clare through Coleman and Midland to Bay City.

What makes the junction odd is a seemingly needless directional light. As shared on a Facebook group dedicated to road enthusiasts, the split has two overhead traffic control devices. There's a 'Keep Right' sign and also a green THRU arrow.

What makes it perhaps unneeded is that there is no other way for traffic to go. Traffic engineers may intended to keep eastbound drivers from entering into the left lane which would be traffic comes from the expressway section of the freeway.

Beyond the THRU green light, you can see what is the first exit on the US 10 expressway for M-115, a major highway in northwest Lower Michigan that runs diagonally from Clare to the Lake Michigan coast at Frankfort.

What they're saying online:

the weirdness of that light.

it's so odd and pointless.

this is just a 2 lane road turning into a 4 lane divided, anywhere else a sign would do.

The lit Keep Right, there's a point - the arrow, not so much

Next time you're passing through Mid to Northern Michigan and you happen along this spot, take a second look at this Michigan highway oddity.
