Hey all,
Although two completely different signs in different states, I have gotten to notice that in both New Hampshire and Maine, they have little green signs scattered throughout the state. Anyone know what either of these mean?
Here is Maine's little green sign (underneath the 209 shield):

And here is New Hampshire's little green sign (similar to what is seen in Vermont and New York):

Any help is appreciated!

They're probably just reference control numbers. Basically they denote points along the highway, using whatever system the agency uses.
Could the 5013 in the first picture be the house number?
The Maine example is a Node Marker.

What is a Node?
The Maine Department of Transportation uses the nodal system to identify segments of highways. The node-and-segement [sic] referencing system is based on uniquely defined points on the highway system. Each point is assigned a unique number called a node number. Node numbers have been designated where the following features occur:
* Governmental boundaries (town and county lines).
* Urban compact lines.
* Public road intersections.
* Public road termini.
* Selected railroad crossings.
* Selected bridges.
* Other selected locations necessary to preserve the integrity of the referencing system.
This was never resolved re: NH's little green signs?
