Bridge Documentation

This is the longest concrete arch bridge of the various bridges which were built on the Florida Keys for the Florida East Coast Railway Extension.

The concrete arch spans were designed with little dependence on steel reinforcing (rebar) because the engineers thought it wise to avoid as much steel reinforcing as possible given the nature for salt water to rust steel.

Today, this is the best preserved of the Florida East Coast Railway Extension bridges, because the entire bridge has been rehabilitated and converted for pedestrian use. Because this section of waterway apparantly does not have any need to accomodate large boats, no sections of the bridge were removed as was the case with other sections. This is also why the adjacent modern highway bridge does not have a high level section.

This page documents one bridge that composed the Florida East Coast Railway Extension, composed of numerous bridges connecting the Florida Keys. Visit HistoricBridges.org's Bahia Honda Bridge page for a number of primary source documents and other materials relating to this bridge and the associated Florida East Coast Railway Extension, as constructed under the direction of the famous Henry Flagler.
