Long Span Structures
The addition of special features such as longitudinal and circumferential stiffening elements to conventional structural plate structures permits the use of spans approaching 60 feet. The tremendous popularity and performance of these larger span structures led to the development of national specifications by the American Association of State Highway and Transportation Officials (AASHTO).
As a service to the industry Lane Enterprises created Long Span Bridge & Culvert (LSB&C) to provide engineering and field services associated with the design and use of long span structural plate structures. LSB&C provides engineering consultation and certified design services to facilitate regulatory approvals, in addition to assembly and construction monitoring during the backfilling operation.
LSB&C helps clients choose from a variety of culvert material and end wall structure types to ensure a complete project that most appropriately meets their structural and aesthetic requirements.
