I poked around the NH Dept. of Transportation website and found this Power Point-type presentation (it's a PDF file) on the Alton Traffic Circle. There are three apporaches they are considering...
1.- Involves two traffic lights.
2.- is for a Round - a - bout like our fine friends up in Meredith are contending with...
or
3.- Some modification of the current rotary.

Existing Condition
Circle was constructed in 1962
Some entrances yield and others do not, causes confusion. Size and shape relate to higher speeds
Not very pedestrian or bike friendly

There is a map with each option.
