These pages contain standard bridge and structure drawings used for the construction of highway projects. The files are approved versions of the Standard ITD Bridge and Structure Drawings which have been modified for use by consulting engineers. The files are intended to be downloaded individually from this site for use on ITD projects.

The files under each individual Section are also available in a WinZip file for each section. All files are in their native Microstation file format.

The Sections listed in the content bar refer to the Idaho Transportation Department Bridge Design Manual.
