Project Development > Bridge Design > Bridge Detail Sheets

The New Hampshire Department of Transportation (NHDOT) makes these documents available on an "as is" basis. These documents are prepared by the NHDOT for use on NHDOT projects. Others who use the NHDOT documents do so at their own risk.

Bridge Detail Sheets are backed by engineering analysis, calculations, crash testing and are approved by NHDOT Administrators and the Federal Highway Administrration (FHWA). Only certain details can be modified by designers. As noted on each bridge sheet, if any modifications are made to details other than those noted, the engineer responsible for the modifications becomes the Engineer of Record (EOR) for those details and all effects the modifications have on other components within the sheet.

Please note that some of the files listed below are large and may take several minutes to download depending on your Internet connection.
