Bridge Design Aids (BDA) are a means to share bridge design information with bridge construction and design professionals throughout the state in a timely fashion. BDAs are not policy. They include a variety of guidance such as answers to commonly asked questions, “good practice” tips, and other topics of interest.
Our hope is that this effort will reduce confusion regarding the Department’s preferences and lead to more uniform bridge plans throughout the state.
When BDA updates are published, notifications will be shared via the INDOT Design Consultants listserv. Subscribe here.
