METRO Green Line

  Transportation, Rail

The second light rail transit line in Minnesota, the METRO Green Line (formally Center Corridor Light Rail) entered service on June 14, 2014. Opening on time and on budget the line was constructed by the Metropolitan Council and it is the largest completed public works project in Minnesota history.

The Green Line together with the Blue Line and The Northstar Commuter Line, provide enhanced and connected transit choices for those living in the Twin Cities area. The 11-mile Green Line travels through many diverse and densely populated urban neighborhoods of the Twin Cities and connects the downtowns of Minneapolis and St. Paul. The line includes destination stops at the University of Minnesota and the Minnesota Capitol Complex in St. Paul. Since rolling out service the average weekday ridership has exceeded all expectations.

Rani Engineering provided the design-level topographic survey for the entire 11-mile corridor, including all intersecting streets and University of Minnesota mitigation areas. Rani also provided Subsurface Utility Engineering (SUE) field work to support Quality Levels A to D (per ANSI standards), and prepared the Right-of -Way (ROW) base map for coordination of construction limits and easements.

Professional services included:

  • Topographic survey & drawings created from almost 200,000 survey points
  • Field work completed with snow and ice conditions during two winters
  • Survey AutoCAD drawings delivered to project office as completed to keep project design moving as data was collected
  • ROW base map created in AutoCAD to Mn/DOT CADD standards while concurrently converted to Microstation for design team use
  • Review of 400-plus subdivision plats and 325-plus detailed legal descriptions and easements to determine the ROW and document encumbrances that could limit corridor construction
  • Survey of underground utility markings for utility impact studies and planned relocation and abandonment in accordance with Federal Highway Administration SUE quality level standards for data certainty and tolerance
  • Assisted in the preparation of more than 6,000 MnDOT UIS (Utility Information System) data sheets for each utility in the corridor – left in place, abandoned or relocated
