U.S. 1 South
U.S. 1 (Overseas Highway) leaves the Seven Mile Bridge and arrives at Little Duck Key. The parallel old bridge provides a fishing pier to the north of the bridge. Little Duck Key otherwise is inhabited. Photo taken 05/07/06.
The Little Duck Missouri Channel separates Little Duck Key from the equally uninhabited Missouri Key. Note another parallel old Overseas Highway bridge to the right. Photo taken 05/07/06.
Another two lane bridge carries the Overseas Highway across Ohio Missouri Channel toward Ohio Key. Photo taken 05/07/06.
Ohio Key is home to Sunshine Key RV Resort. The mobile home community encompasses all land between U.S. 1 and Florida Bay. Pictured here is the Ohio Bahia Honda Channel bridge. Photo taken 05/07/06.
U.S. 1 southbound enters Bahia Honda Key, a large island protected by Bahia Honda State Park. The Overseas Highway widens to four-lanes for the next four miles. Photo taken 05/07/06.
Four-lane U.S. 1 approaches the entrance to Bahia Honda State Park. Activities popular within the state park include snorkeling, swimming, and fishing. The 524-acre island began its transition into a state park with a 13-acre purchase by the state in 1961.1 Photo taken 05/07/06.
The Bahia Honda Bridge carries U.S. 1 west from Bahia Honda Key to the Spanish Harbor Keys. Paralleling the highway bridge to the south is the original 1912-completed Florida East Coast Railroad bridge. Rail service to Florida Key West ended when the Labor Day Hurricane of 1935 destroyed over 40 miles of track. The state purchased the right-of-way in 1936 and began constructing the original Overseas Highway. The 1938-opened roadway included the conversion of the Bahia Honda railroad truss bridge into use as a highway bridge. This entailed constructing a concrete deck on top of the existing superstructure.2 Photo taken 05/07/06.
Midway across the twin Bahia Honda Bridges on U.S. 1 southbound. Opened in 1972,2 the concrete bridges that carry U.S. 1 today replaced the aged two-lane span to the south. The Bahia Honda Bridge spans the deepest channel in the Florida Keys at 35 feet.3 Photo taken 05/07/06.
Southbound travelers reach the uninhabited Spanish Harbor Keys. An abandoned structure and pipeline lie to the south of U.S. 1 at the west end of the severed Bahia Honda railroad Bridge. The four-lane highway quickly reduces to two lanes ahead. Photo taken 05/07/06.

Like most other bridges, the 1938-Overseas Highway bridge parallels the current Overseas Highway bridge close by as a fishing pier. Spanish Harbor lies to the north. U.S. 1 turns northwest at the west end of the bridge. Photo taken 05/07/06.
Entering Big Pine Key and the National Key Deer Refuge on U.S. 1 south. U.S. 1 kinks northward toward the built-up areas of Big Pine Key. Big Pine Key, named for the pine trees that grow on the island, is just over 5,800 acres in area. Oolitic limestone comprises much of the island, and these rocky formations contain pockets of fresh water. Despite the small sized of the island, Big Pine Key is home to the most fresh water of any Florida Key.4 Photo taken 05/07/06.
Large caution signs lie at both entrances to the National Key Deer Refuge. Established in 1957, the wildlife refuge protects the endangered species Key Deer on both Big Pine and No Name Keys. There was an estimated 800 Key Deer alive in the mid-2000s, up from an estimated 27 in 1957. Key Deer are the smallest member of the Virginia white-tailed deer species. Bucks stand between 28-32" with an average weight of 80 lbs.5 Photo taken 05/07/06.

The speed limit varies between 45 mph during the day and 35 mph at night through the National Key Deer Refuge. A wildlife underpass allows the deer to cross from one side to another without interacting with U.S. 1. Metal fences line along the Overseas Highway right-of-way otherwise to protect the Key Deer from the busy road. Photos taken 05/07/06.

No Name Key lies east of Big Pine Key across the Bogie Channel. The island primarily is undeveloped and is part of the National Key Deer Refuge. There are a few beach houses however on the northwest corner of the island. Photo taken 05/07/06.
Use former Monroe County Road 940 north for the National Key Deer Visitor Center, Blue Hole (a freshwater pond created from an abandoned oolite quarry), and the Big Pine Road Prison. Watson Boulevard represents the original Overseas Highway east from its end at Pine Channel to Bahia Honda Channel at the east end on No Name Key. The original road was signed as SR 4A originally.
