Bridge Sheets are backed by engineering analysis, calculations, crash testing and are approved by NHDOT Administrators and the Federal Highway Administrration (FHWA). As noted on each Bridge Sheet, only certain details can be modified by designers. If any modifications are made to the details that shall not be modified, the engineer responsible for the modifications becomes the Engineer of Record (EOR) for those details and for all effects the modifications have on other components within the sheet.
