Bridge Design

I am looking for a bridge designer to build a Beam Bridge out of steel for vehicle traffic. The bridge must meet all necessary structural, safety and engineering requirements for the intended purpose. Experience in bridge design is essential to be considered for this project. The bridge must be designed with an understanding of the environment and the predicted use to ensure maximum longevity. I'm looking for a professional who has the skills, knowledge and best practices to create a safe and aesthetically pleasing bridge structure. The end result must bring long-term value and function to its environment.
The bridge would be for a private drive over a river, approximately 30 feet long and 14 foot wide. I-beam construction with wood deck consisting of planks of appropriate thickness for loads intended.
