Grade Separation Systems is an innovative method developed by art engineering inc. for constructing rail-highway underpasses without using expensive temporary tracks, structures, or long-term closures. It provides a more cost-effective alternative to traditional grade separation projects, with potential savings of up to 45% by avoiding the need for temporary works, foreign technology, or shoofly tracks. The system utilizes common heavy civil construction techniques to separate highway and rail lines in a way that meets North American safety standards and allows for year-round construction.

construction of underpasses at rail-highway grade crossings.
What Is ?
Grade Crossing Underpass

3. Rail-highway grade crossings are one of the biggest problems
with modern infrastructure, causing hundreds of deaths each
year.
Rail Crossing Issues

4. There are over 100,000 public rail-highway grade crossings in
North America that are still in use, leaving lots of potential for
accidents.

5. Although preventing accidents is the top priority, other rail-
highway crossing issues can be resolved with grade separation.

6. Why Do We Need ?
Current grade separating methods are expensive, often
making separation projects infeasible.

7. How Is Different?
GSS is a more efficient method that avoids long term closures,
rail detours, and temporary structures altogether.
These improvements allow for significant savings – up to a 45%
reduction in project costs.
Innovative method
No temporary structures
No rail detours
Common heavy civil techniques
Meets all North American standards
Year round constructability
