Grade Separations and Approach Ramps

Grade separations and approach ramps 1 Grade separations and approach ramps 2 Grade separations and approach ramps 3

Supporting the heaviest railway loads, our Structural Steel PlatePrefabricated Bridges and Retaining Wall Systems are go-to solutions for today’s busy rail systems needing accelerated design and construction. Our ability to economically package these solutions makes them frequent companions in grade separation and approach ramp applications.

Our versatile and attractive Structural Plate overpasses and underpasses are designed to meet railway clearances well beyond your needs. Ultra•Cor® or Super•Cor® Arches and Box Culverts, are recommended for larger applications. Bolt-A-Plate® is well-suited to less demanding applications and offers the widest array of size and shape configurations.

Box Culverts

Box Culverts1 Box Culverts2 Box Culverts3
Featuring a unique geometry for generous rail or road clearances, Box Culverts are the perfect solution for long-span, low-rise situations with shallow cover requirements. We offer many different possibilities in Box Culverts in Ultra•Cor® or Super•Cor® Structural Steel Plate or Dur•A•Span™ Aluminum Structural Plate — each one ready to shoulder the load for many years of low-maintenance service.

With difficult terrain and sensitive ecosystems, these crossings require extra care and engineering expertise. We can provide many types of solutions from Prefabricated Bridges and Structural Steel and or Aluminum Plate for larger applications, to Corrugated Pipe for smaller ones. Naturally, our wall systems are always ready to lend their support for abutments, headwalls and the like.

Durable and low-maintenance Modular Railway Bridges are designed by our in-house engineering team to meet the most stringent regulations and decrease or eliminate environmental impacts. Prefabricated Pedestrian Bridges are ideal for today’s demanding light rail and intermodal crossings. Modular components for spans up to 400' (122 m) can be installed in one day for limited interruption to rail traffic.

Our engineered Vist-A-Wall MSE Structural Wall Systems® create cost-effective on-site abutments and retaining walls. They are available in a variety of Precast Panel finishes or as Wire Walls with natural cobblestone at the face. Our Two-Stage Precast Walls are ideal for areas where excessive settlement is anticipated. Vist-A-Walls’ flexible design works well around various types of obstructions such as steel piles. Our Bolt-A-Bin®, cellular metal bin type walls are another economical option for abutments or steepened slopes.
