At Di Highway Sign and Structure we have a very experienced engineering department that is available to work with every customer that purchases product from us. Based on the materials that we consistently fabricate we are an AISC certified shop for simple bridges and this is where most of our engineering work is concentrated. Another strength of our engineering department is Overhead Sign Structures. Over the years Di Highway's engineering department has worked with numerous state agencies including New York, Vermont, and Connecticut. The projects that they have completed are so varied that it would be impossible to list them here. On a daily basis our engineers work within customer plans and specifications to produce a high quality product for fabrication. Generally Di Highway's engineering department is not categorized as "Design-Build" but it does have the resources for proffesional engineering stamped designs when required.
