ECO-SPAN® offers comprehensive engineering tools and technical support to expedite the concrete arch design process and reduce engineering costs.
Instant Design Center
ECO-SPAN® Instant Design is an intuitive, quick way to tell us about your project. Our Instant Design form includes many aspects of three-sided bridge best design practices built in to guide users to the most effective use of a precast arch at their site. After you complete the form, we will send complimentary project-specific application drawings within a few hours. Budget estimates are generally available within one business day. Site plans and additional information or questions may be sent to [email protected].

Non-Proprietary Arch Shapes
One of the ways we reduce costs is through our non-proprietary arch shapes. These “open source” arch shapes are just as efficient – if not more efficient – than proprietary arches. We recommend showing non-proprietary arch shapes on the plans, which opens the project to the most bidders and potentially reduces the price for the owner. Need assistance? Just let us know.

AutoCAD .dwg and SketchUp .skp blocks are available for download in our CAD Library.
