SuperSill for Modular Vehicular and Pedestrian Bridges
- The SuperSill is a steel concrete abutment form.
- This bridge structural support system applies a corrugated sheet, wide-flange W-beam, and welded supports to a heavy duty, high quality frame.
- Pre-engineered and standardized to eliminate unique abutment design fees.
- SuperSill prefabricated abutments eliminate unnecessary on-site forming and installation costs due to idle labor and equipment.
- The bridge abutments can also be shipped empty, on the same truck as the bridge, removing the requirement of shipping low-value concrete from the plant to the jobsite
- SuperSill bridge abutments are designed to support a variety of soil conditions without the need for piling.
- Certified for Steel Plate Girder Bridges
Our Process
- Perched abutment.
- Includes integral backwall providing interface between bridge and approaches.
