Land Area

Water Area

Land area is a measurement providing the size, in square miles, of the land portions of geographic entities for which the Census Bureau tabulates and disseminates data. Area is calculated from the specific boundary recorded for each entity in the Census Bureau's geographic database. Land area is based on current information in the TIGER® data base, calculated for use with Census 2010.

Water Area figures include inland, coastal, Great Lakes, and territorial sea water. Inland water consists of any lake, reservoir, pond, or similar body of water that is recorded in the Census Bureau's geographic database. It also includes any river, creek, canal, stream, or similar feature that is recorded in that database as a two- dimensional feature (rather than as a single line). The portions of the oceans and related large embayments (such as Chesapeake Bay and Puget Sound), the Gulf of Mexico, and the Caribbean Sea that belong to the United States and its territories are classified as coastal and territorial waters; the Great Lakes are treated as a separate water entity. Rivers and bays that empty into these bodies of water are treated as inland water from the point beyond which they are narrower than 1 nautical mile across. Identification of land and inland, coastal, territorial, and Great Lakes waters is for data presentation purposes only and does not necessarily reflect their legal definitions.

    State Bridges Listing as of July 2018 Transportation

    data.pa.gov | Last Updated 2018-10-04T12:49:51.000Z

    This is the total listing of all State Bridge structures for the Commonwealth of Pennsylvania, with designation fields for the structures to be repaired or replaced under the 2015-2020 Governor’s Structurally Deficient Bridge Goal. Let – award (a contract for a particular project) to an applicant RBR - This public-private partnership (P3) Rapid Bridge Replacement Project was awarded by the Pennsylvania Department of Transportation (PennDOT) to the consortium of Plenary Walsh Keystone Partners (PWKP). The Commonwealth of Pennsylvania is taking advantage of the new P3 tool, signed into law in 2012, to address the state’s roughly 4,500 structurally deficient (SD) bridges. “N” or “- -“ is null or no information DEMO - means the structure has been demolished. The project is an initiative to replace aging bridges throughout Pennsylvania. Replacing the bridges will provide motorists with new, modern structures and allow PennDOT to remove them from their structurally deficient list. The bridges are primarily crossings on smaller state highways, many in rural areas, rather than interstate bridges or large river crossings. This database contains inspection, selection and schedule information and therefore may not be used in legal actions or proceedings against the bridge owner. Furthermore, all information contained herein is subject to change without notice. (Reference 65 P.S. Sec 66.1 et sep., 75 pa C.S. Sec 3754 and 23 U.S.C. Sec 409.)
