Fort Greene was built as part of a general modernization of US coastal defenses, begun in 1940 with the outbreak of war in Europe and the fall of France. The goal was to replace all previous heavy weapons, most of which were over 35 years old, with long-range ex-Navy 50 caliber Mark 2 guns. Lighter weapons would be replaced by 6-inch guns on high-angle shielded barbette carriages. Ammunition magazines and the 16-inch guns would be in casemated bunkers to protect against air attack.
The fort was intended to protect the approaches to Narragansett Bay, and with a range of over 45,000 yards it could protect the eastern approaches to Long Island Sound.

One of the oldest roads in the state, Fort Road was originally built by the federal government after Fort Ridgely was completed in 1853-54. Supplies were shipped from Fort Snelling to Traverse des Sioux, then transported by wagon to Fort Ridgely.
Nicollet County Road 5 runs more than 42 miles from its eastern terminus at its intersection with US Highway 169 in St Peter to the Renville County line. Old Fort Road presumably extended from Traverse des Sioux, although the portion running through the campus of Gustavus Adolphus College has been blocked off. Fort Road as an address runs from the western edge of St Peter to the end of CR-5.
In an ideal world, a paved trail would have been installed when the road was refurbished in the early 2010s. This planned geocache trail will have to suffice, but won’t alleviate my anxiety when biking here.
