[1] Gross was the name of a small turpentine village along the Seaboard Air Line main line about 7 miles north of Yulee (near the current interchange between Interstate 95 and US 17).

The Gross Cutoff was built in 1925 and acted as a bypass for the busy Jacksonville Terminal area, which trains would have to otherwise pass through.

Trains could then continue from Callahan to the Seaboard main line in Baldwin.

Its heavy use also cause the Seaboard Air Line to abandon the old Florida Railroad from its connection with the Gross Cutoff in Callahan to Yulee in 1954.

The merged company was named the Seaboard Coast Line Railroad.
