About the County Bridge Inspection/Inventory Data


The Data
The data shown on the website is continuously updated. That means when sufficient new or updated data is recieved from the counties a new master compiliation file and internet files are created. Because of that, each page displays the date and time it was created: This page created: 11/12/2002 02:03:38 PM. This date is not the date whern the data was collected. The date when the data was collected is the Date of Last Inspection or Inspection Date.

Inspection Reports
There are two types of pre-formatted reports available for individual county bridge data records: Annotated and Comprehensive. These two reports detail important information, obtained from the National Bridge Inspection and Inventory database, but do so using different levels of detail and complexity.

The Annotated (Supervisor) Report was designed to present the most pertinant information in a easy-to-read and understand format for the county's Boards of Supervisors.

The Comprehensive Report lists all of the National Bridge Inspection and Inventory data collected on a particular structure. The data presented is in the NBISS Code format. The data items not numbered are not included in the NBISS reporting requirements but are collected by the County Engineer to assist the county in completely assessing the condition and repair/replacement priorities. The current NBISS Bridge Inventory Coding Guide can be downloaded here: mtguide.pdf 779k [FHWA link]
