The Overseas Highway
The Overseas Highway is the 128 mile stretch of U.S. Highway One that connects mainland Florida to Key West. The roadway was initially built as a railway for Henry Flagler's ambitious Overseas Railroad. The railroad served to connect the keys to the mainland for twenty-three years from 1912 until 1935 when it was destroyed by a hurricane.
Sections of the old railroad were used to build the highway in stages, and since the 1950s the Overseas Highway has replaced the railroad as the only connected land transport thoroughfare from the mainland to Key West.
The Seven Mile Bridge crosses Moser Channel and connects Knight's Key (a part of Marathon) in the north to Little Duck Key in the south. Marathon is considered the south end of the middle keys. Therefore, once you make landfall on the south side of this jarringly long bridge, you are officially in the lower keys.
Physical Attributes & Geography
The driving surface of the 7 Mile Bridge is relatively flat for the most part, with a high-rise section at the midway point that crosses the navigable cut of Moser Channel. Large vessels traverse under the bridge's high span. The Atlantic Ocean extends from the south side of the bridge, while the Gulf Of Mexico and Florida Bay extend from the north side, with the line of the bridge dividing the two.
One-third of the way across the bridge when heading south you will find Pigeon Key to be visible on the Gulf side. Pigeon Key is an old pioneering settlement that is now used by the University Of Miami for marine biology studies. Pigeon Key is also open to the public through guided yours of the island.
Just south of Pigeon Key and out in the Atlantic waters is Molasses Key. The view of Molasses Key from the 7 Mile Bridge, with its coconut palms, white sand beaches, and turquoise surrounding waters is one of the most thrilling sights for anyone driving to the lower keys. To me, when I see that tropical island, I always feel like I am finally on island time.

History & Construction
The bridge as it stands today was opened in 1982. It is actually 6.79 miles in length. It has a clearance of sixty-five feet under its highest span (at high tide that is). The structure's construction is that of a precast segmented box girder system. A box girder bridge is one that has main beams composed of hollow box runners of, usually, some form of reinforced concrete. It is the same system often used to construct highway overpasses.
Construction cost was $45 million, and it was completed six months ahead of schedule. It was engineered by Figg & Muller Engineers, and has earned several engineering and construction awards. Among the accolades bestowed upon the bridge is the Federal Highway Administration's prestigious Exceptional Award for Cost Savings Innovation.

Things To Do In The Area
There is no shortage of activities in the vicinity of the longest Overseas Highway bridge. One of the most famous is the 7 Mile Grille, located at the base of the northern end of the bridge's landing at 1240 Overseas Highway, Mile Marker 47.5 in Marathon, Florida 33050. The 7 Mile Grille has been a keys landmark since 1954. The 7 Mile Grille features "Catch And Cook" service, which allows visiting anglers to bring in their catch and the restaurant will cook it for you! The location advertises free wi-fi, and they are also said to have the best Key Lime Pie in the keys (although that designation has been given to far too many establishments to count at this point).
Marathon Key to the north and Little Duck Key to the south are both renowned fishing and diving locations, The surrounding waters hide coral reefs, lobster, snapper, grouper, and many more sport fish. On Marathon you can rent Jetskis, and charter fishing and snorkeling trips. Both Marathon and Little Duck Key are also both outstanding places for a kayak paddling adventure.
