Disclaimer: The Bridges and Structures Bureau is committed to providing accurate electronic files of our standards. With our migration from Bentley V8i to the Bentley CONNECT platform, the formatting of the .dgn files changed. Many standards available at the links below and through ProjectWise have been updated. We recommend that users of these .dgn files compare their resulting project sheets to the provided .pdf files to ensure the intended results. Edits to the .dgn file format are acceptable at the discretion of the user.
Back to topUpdate Notice
The bridge standards available on this page include an 8.5” standard deck thickness and single slope bridge rail. The newly released standards can be used immediately. These standards were developed using the Bentley Connect Edition of MicroStation.
The Master Common Details file contains common details that are referenced by several groups of standards. This file shall be used in combination with the groups of standards to provide the common details referenced to the sheet models.
The Bentley V8i format of these bridge standards are no longer available on our website. The older format of the standards can be accessed through the Iowa DOT Electronic Reference Library Archives.

UPDATE NOTICE: The Beam Standards dated April 2024 were completed using an older Engineering Vert font and not the updated Engineering Vert font with correctly mapped symbols. The use of these standards in a CADD file with a ProjectWise managed font will cause discrepancies of special characters and symbols. Please see related information on Fonts (189.42 KB) .pdf . These standards will have to be manually corrected when used at this time. These standards will be released in the future with the corrected characters. The related LEAP information for these Beam Standards is available under the Final Design Software.
