BRIDGE & CROSSING DESIGN

Bridge & Crossing Design

StoneCroft is a leading provider of general arrangement and detailed structural design services for bridges, pedestrian bridges, major culverts, arches and fords in the natural resource sector. Designing bridges and crossings is how we got started in 1989 and remains a key part of our business.

StoneCroft typically assumes the role of Professional of Record. We work closely and collaboratively with the Coordinating Registered Professional and the required team of specialists (e.g., biologists, geotechnical engineers) to satisfy the professional requirements related to the project. Our focus is on user safety, constructability, structural integrity and sound environmental management. We are known for providing practical, innovative and cost-effective designs.

  • Bridge Superstructure Designs:
      • Log or Timber Stringers
      • Steel, Concrete and Timber Deck Portables
      • Steel/Concrete Composite 
      • Steel Pipe

Our bridge and crossing design services:

StoneCroft can take your bridge or crossing project from proposal through feasibility to construction, assurance and ongoing maintenance. We offer full life cycle bridge and crossing asset management. 

Where a StoneCroft design stands out is its constructability. Having been the Construction POR for most of our designs, we consider constructability and worker safety requirements like tote road widths and operability of compaction equipment in steep terrain. We want the project to be a success for our clients from the start.
