GSS is our latest innovation: a cost effective method for the construction of bridge underpasses at any live traffic intersection.

It is a construction method to eliminate level rail crossing intersections by building an underpass in a fraction of the time and cost that traditional methods have previously proposed. This is done by eliminating rail traffic detours and performing construction operations in rail closures of as little as four hour closures at a time. GSS increases public safety by building underpasses faster and cheaper than ever before, increasing the feasibility of these much-needed infrastructure projects.

Build your underground grade separation smarter. Eliminate rail detours and increase intersection safety with significant cost and time savings.
