AASHTOWare Bridge Design and Rating Software Modernization

The AASHTOWare Bridge Design‐Rating Software Modernization Solicitation was forwarded to AASHTO Member Agencies on September 22, 2015. Agencies were encouraged to consider participation in this important development effort to support the future of the AASHTOWare Bridge Design‐Rating software. To achieve this important national objective, AASHTO is soliciting agency’s voluntary participation in this cooperative effort. The project funding goal has not been met; however, through the use of license fee revenue to support a portion of the modernization activities in the first two phases of the project coupled with alternative financing strategies, we are in a position to start the project on April 1, 2016. Participating states have received a detailed updated. As states continue to respond, their much needed participation contributions will reduce the need for pushing the financial burden of the project past FY2020. Many states have not yet responded to the solicitation, so if your agency has not responded, we encourage you to respond, even if you are unable to participate, so we can make the best financial decisions for the product.
