State Road 166 (SR 166) is a 5.054 miles (8.134 km) long state road in Jackson County, Florida, running from US 90/SR 73 in Marianna, Florida to SR 71. The road is almost entirely two lanes wide, except in portions where third center left turn lanes appear.
Despite ending in an even number, the road runs mostly north and south in and north of Marianna, Florida. While most of the road is signed as a north-south road, the northernmost portion is signed as an east-west road.
State Road 166 begins as Jefferson Street at the southeastern terminus of the US 90/SR 73 concurrency, taking a secret concurrency with County Road 167 from SR 73. Two blocks north at Clinton Street the road runs between the city fire department and the First Presbyterian Church. At Davis Street, the route leaves the Marianna Historic District. Just north of there, the road begins to curve just to the northeast as it officially leaves the city at the intersection of Kelson Avenue, one side of which leads to Chipola College. Despite leaving the city, many businesses along this stretch of the road are still named for and addressed as being in Marianna. Taking a slight curve to the east the route approaches another road leading to Chipola College named River Forest Road, then the name changes from Jefferson Street to Caverns Road, which continues to make a more easterly curve as it approaches the bridge over the Chipola River. The easterly curve ends as the road returns to ground level from the embankment of the bridge.
