This data set contains historic bridge locations and basic bridge attributes as recorded at the Florida Master Site File.
The data was created to serve as base information for use in GIS systems for a variety of planning and analytical purposes.
publication date
The locations of archaeological sites, historic structures, unmarked human burials, bridges, and other cultural features contained in this (and other) Site File data layers are for resource management, law enforcement, and research purposes only. State law protects archaeological remains on state owned and controlled lands (section 267.13, Florida Statutes). State law protects human burial sites on all lands (sections 872.02 and 872.05, Florida Statutes).

GeoPlan relied on the integrity of the attribute information within the original data.
The historical bridge data are based on field reports which have been submitted by many and varied individuals, groups, institutions, and cultural resource firms. Submissions to the Site File are sometimes accepted from amateurs as well as professionals. The locations are only as accurate as the locational information submitted to the Site File by the site recorder. The accuracy of submitted information cannot always be verified. The absence of a cultural resource in this data layer does not preclude the existence of an unrecorded resource in the field. The bridges recorded at the Site File represent only a fraction of the historic bridges present statewide.
This data set updates and replaces all previous versions of the Florida Master Site File historical bridges data layer. This version incorporates newly recorded bridges and updates of previously recorded ones. Data from the Florida Master Site File are continually updated. This data layer is only current as of the date of this document. Contact the Florida Master Site File for updated data layers.

Spatial and Attribute Information
Source data were created by the Division of Historical Resources. The original location data are based on field recording forms and map plots submitted to the Site File. Florida Master Site File site folders contain an historic bridge form with descriptive location data, photographs, and any site plots provided by the surveyor. This data layer is maintained by on-screen (heads-up) digitizing bridge locations in ESRI ArcMAP. Scanned, georeferenced, 1:24,000 scale USGS quadrangles in geographic coordinates (lat./long., NAD27) are used as the background reference images.
When received by GeoPlan, the data was in the following projection: Geographic, Datum: WGS 1984 Units: Decimal Degrees. The shapefile was projected to FGDL Albers HPGN in ArcToolBox using the following transformation: WGS_1984_(ITRF00)_To_NAD_1983 + NAD_1983_To_HARN_Florida -Reprojected to FGDL Albers HPGN -Added DESCRIPT field based on SITENAME to attribute table -Added fields FGDLAQDATE -Upcased all items in the attribute table -Changed file name to shpo_bridges_OCT17 from HistoricalBridges

ESRI
This is the official state site number assigned by the Florida Master Site File. The state site number is an eight character string containing a two character county code, a five character numeric code, and an optionalsingle letter character suffix (suffix letter is generally used to indicate sites that are functionally or spatially related).
Bureau of Archaeological Research
The bridge name as recorded at the Florida Master Site File. This is usually the principal or best known name for a cultural resource.
Bureau of Archaeological Research
The serial number assigned by the Site File to the manuscript produced by the project which identified or reexamined the cultural resource. Not all bridges have an associated report or manuscript.
Bureau of Archaeological Research
The FDOT number is six positions in length, with the first two numbers as the defining code for the county. The remaining four positions are used as a unique number for the bridge within the county. A zero value for this field indicates there is no FDOT number for the bridge.
Bureau of Archaeological Research
The initial date of the bridge's physical construction. A value of 'UNKN'for this field indicates the year of construction is unknown.
Bureau of Archaeological Research
The overall condition of the bridge.
Bureau of Archaeological Research
Overall length of the bridge in feet.

Date that the site was officially listed on the National Register of HistoricPlaces (NRHP). The field is blank if the FMSF database does not indicate the property is National Register listed.
Bureau of Archaeological Research
Evaluation of Florida's State Historic Preservation Officer (SHPO) concerning the eligibility of the resource for listing on the National Register of Historic Places. In Florida, the SHPO is the Director of the Division of Historical Resources, acting through staff in the Bureau of Historic Preservation (BHP). Generally the Site File database only contains evaluations made by the Compliance Review staff of BHP. Some properties may be listed on the NRHP without having been reviewed by Compliance Review staff. Therefore, an NR list date (indicating a property is NR listed) takes priority over a 'Not Evaluated by SHPO' value in this field. Values in this field are limited to a discrete list of possibilities used in the Site File database lookup table. Contact the Site File for more information.

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.
