Copper was chosen for the Central Corridor Light Rail East for its longevity, exceptional durability and resistance to corrosion in any environment. Further, copper was the obvious material for this project because it complemented the overall aesthetic of the historic areas of St. Paul, Minnesota.  This project was a challenge because the transit stations on either ends needed to be finished before starting the others, thus expediting its schedule.  In total, there were 14 stations along a 7-mile long track with very limited access for the workers.

The Central Corridor Light Rail East project used approximately 8,500- 21,000 pounds of solder.  Every hook seam panel that was installed needed to be pre-tinned on all four sides prior to finishing fabrication to ensure a quality solder joint. Additionally, 11,592 panels of copper were used for 14 stations on the project.  Copper was also used for drains, gutters, nosing, roofing and more to make this project complete.
