COLT Hub trains rolling on Super-Cor structure

North Dakota’s oil boom is taking off but, with no pipeline in the area, large infrastructure developments are needed “yesterday” to get the crude to the refineries and markets. And, the COLT Hub is no exception.

As the largest crude oil loading terminal in the state, it was designed to aggregate and distribute over 120,000 barrels a day to multiple downstream markets through unit train loading. The terminal’s double-loop track layout called for a rail-over grade separation to access the interior of the site.

Known for our ability to fast-track design, fabrication and installation processes, AIL Mining was contracted to design and supply a Super-Cor Arch with MSE headwalls and wing walls.

Super-Cor: Accelerated schedule and reduced cost
Working with the consultant and the contractor, we streamlined the approval process so initial fabrication could begin earlier than normal. Our engineered solution met the accelerated construction schedule, reduced the cost and installed without interrupting the track installation.

Super-Cor’s strength handles multiple E80 rail traffic
Super-Cor’s strong corrugation profile could handle the heavy loadings of multiple lanes of E-80 rail traffic and deliver the additional benefits of a (12.2 m) 40′ clear span and only 83.8 cm (33″) of cover. In fact, the bridge’s generous clearance box came in handy when construction crews needed to transport a large mechanical tower through it.

  • Urgent bridge replacement: from site prep to first train in 120 days

    AIL Mining partnered on a mine site infrastructure project to replace a 60 m span steel girder bridge that had been damaged during severe “once-in-500-years” flooding. The team had a 12-month window and, thanks to the concerted efforts of all project partners, the bridge was up and running within eight months.

  • Super-Cor Bridges angle in on budget to support double track load

    When a new rail spur had to cross a protected southern Indiana stream to deliver coal to a thermal generating plant, minimum structural depth, a skewed alignment and heavy storm flows were the critical constraints. The project team had looked at various solutions — precast beams, steel beams and precast arches — but they were unable to get the designs to work efficiently within the constraints.

  • Latin America’s largest steel box culvert keeps a low profile in Peru

    With the rainy season coming soon, this customer wanted a faster, more economical alternative to a cast-in-place bridge for their remote Puente Ccalaccapcha stream crossing in Peru. It needed to be easy to assemble, have a low profile for grade requirements and have a wide mouth for optimized hydraulics.

  • Prefabricated Bridge provides heavy-duty access to LNG gate station in PA

    A major energy infrastructure company needed a permanent bridge constructed over a stream crossing to gain access to a liquified natural gas (LNG) gate station for the installation of two-way piping beneath the Susquehanna River in Drumore, PA. Their project partner, Pinnacle Design/Build (PDB), recommended a heavy-duty Modular Bridge from AIL Mining.
