Metro Transit

TKDA at the forefront of transformative transit infrastructure with Metro Transit partnership

TKDA’s relationship with Metro Transit began in 2001 as part of the Hiawatha Corridor (Blue Line) Light Rail Transit (LRT) project team, providing design for the LRT Operations and Maintenance Facility (OMF) and documentation for many LRT stations. When the Central Corridor (Green Line) moved forward a decade later, TKDA was again part of the larger team contributing to that line’s success. A major TKDA contribution to this phase was the design and construction administration of the OMF’s expansion, which included a sophisticated geothermal heating and cooling system.

TKDA has also helped Metro Transit build out and maintain its extensive facility infrastructure of control centers, bus maintenance facilities, park and rides, and transit hubs, along with commuter rail studies and infrastructure. Much of this work was completed under master contracts that address ongoing needs and system upgrades, including:

  • Garage vehicle lifts, floor repairs, fall protection, boiler replacements, and exhaust improvements
  • Electrical switchgear, distribution, and solar conversions
  • Security upgrades
  • Bridge and tunnel inspections
  • Window and door replacements
  • Space planning


Headquartered in Saint Paul since our founding—with the Green Line at our front door—it is exciting for us to witness and be part of the region’s transformation as Metro Transit goals are realized.
