Grade Separations and Approach Ramps 

Supporting the heaviest railway loads, our Structural Steel Plate, Prefabricated 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.


Overpasses and Underpasses 

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 

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.


Water and Wetland Crossings 

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 or Aluminum Plate for larger applications, to Geotextile Reinforced Soil Bridges and Corrugated Pipe for smaller ones. Naturally, our wall systems are always ready to lend their support for abutments, headwalls and the like.


Vehicular and Pedestrian Bridges 

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 122 m can be installed in one day for limited interruption to rail traffic.


Abutments and Retaining Walls 

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.


Headwalls and Wingwalls 

Our ability to design and supply buried arch bridges and their headwalls and wingwalls as a packaged solution creates additional opportunities to maximize value in railway infrastructure. Our Vist-A-Wall MSE Structural Wall Systems® site-adapt easily to steps, angles, curves, and other site anomalies. Other solutions are also available in different materials.


Sound Barrier Walls 

With their lighter weight, lower installed costs and long-term durability, AIL Sound Walls are a perfect choice to keep the peace in neighbourhoods along busy railways. They are installed easily on narrow job sites and are available in several attractive colours and configurations to satisfy important aesthetic considerations. Many of our installations have been replacements for deteriorating concrete systems.


Culverts, Fish Passages and Drainage 

We offer various types of fish passage solutions. Our corrosion/abrasion resistant Dur•A•Span™ Aluminum Structural Plate is particularly well-suited to saltwater or aggressive environments. We also offer different finishes on Structural Steel Plate for extended service life. Specialized fish baffle inserts are available and open-bottom designs decrease environmental impact.


Rehabilitation and Relines 

Our reline packages can help salvage older culvert or bridge structures and avoid the cost, traffic interruption and environmental issues of a full replacement. Custom-fit inserts can be made from Corrugated Pipe or various profiles of Structural Plate. One of our latest innovations, THE EDGE Super•Cor® Flange Connection, allows liners to be completely built from one side.
