South Florida East Coast Corridor Transit Analysis
1.0 INTRODUCTION
The Florida East Coast Railroad (FECRR) traverses through Miami-Dade, Broward and
Palm Beach Counties and is generally parallel to Dixie Highway and US-1. Currently, in
the tri-county area, the FECRR is used exclusively for freight movement. As
redevelopment and infill in the older eastern communities of South Florida has been
encouraged, discussion of returning passenger service to the FECRR has emerged.
After some individual efforts, the three counties agreed to embark on a regional study of
the feasibility of using the FECRR for passenger service. The Florida Department of
Transportation, District 4, was selected as the appropriate agency to manage the
project and in October 2005, the South Florida East Coast Corridor Study (SFECC)
study was initiated.
The study area follows the FECRR right-of-way from approximately West Flagler Street
in Downtown Miami to Indiantown Road in Jupiter.
The SFECC study includes assessing the complex relationships among existing and
future freight and goods movements with the need to develop new transit travel capacity
in South Florida. The study corridor is undergoing significant redevelopment and
densification that is likely to continue given the projected increase in population in the
next thirty years in the region. At the same time, the three ports (Port of Miami, Port
Everglades, and Port of Palm Beach) serving the region have focused on the FECRR to
meet increasing demand for intermodal freight capacity. The SFECC study area is
served by existing Tri-County Commuter Rail (Tri-Rail) service that could be
complemented and enhanced by new service and/or connections to employment and
residential centers that are adjacent or near to the FECRR right-of-way.
There are a total of 30 bridge structures along the study corridor. The FECRR owns
and maintains a total of 17 these bridges. The bridges are numbered from north to
south according to their milepost location along the FECRR. The remaining 13 bridges
are overpasses. Figure Nos. 1, 2, and 3 present the general location of the bridge
structures in each of the three Counties (Palm Beach, Broward, and Miami-Dade
County). The purpose of this report is to provide relevant general information regarding
the characteristics of these bridges.
