The Enviro-Span system is a modular culvert solution suitable for use over fish bearing or environmentally sensitive streams without disturbing the stream bed. Enviro-Span can be used in permanent and temporary applications. It is extremely easy to install due to its light weight, ease of handling, and elimination of cumbersome footings and fasteners for assembly. It is a clear span that requires minimal or no site preparation in temporary (or even semi-permanent) crossings.

Sensitive fish bearing and fish contributing streams can be crossed in any season as no excavation either in-stream or on stream banks is required for most crossings. Heavy equipment is at no time required to cross through the stream as all of the work can be done from one side until the fill is sufficient to cross over. Enviro-Span modules come as either straight or angled pieces, designed to follow the natural curves of a stream without requiring channelization.

Standard resource extraction road crossings can be completed from start to fully loaded truck traffic in as little as 3 hours.
