Easement Agreements

Skyway 37 Agreement (PDF)

Skyway 52 Agreement (PDF)

TPT & Union Depot Skyway & Street Levels (Bridge 37 doc)


The Bridge 51 document, in part 1 references an “Agreement” attached as “Exhibit A”, but there’s no attachment shown. Then immediately in part 2 it’s stated that an agreement can’t be located. Are parts 1 & 2 referring to the same agreement, or is part 1 referencing a recreation of the missing agreement indicated in part 2, but then not included in the provided document?

Bridge 52 was proposed to cross Sibley St. between Kellogg Blvd. and 2nd St. connecting the old Post Office (Custom House) to the Union Depot concourse. I don’t believe it was ever built. I don’t know why it has a bridge number.


A comprehensive guide to the climate controlled city owned bridges that make the skyway the skyway. 


Essentially the same information presented in the bridges section, only sorted by building.


Why is this door locked? Where ARE the doors? How do I get in? How do I get OUT? Skyway access is one of the more perplexing aspects of the DtStP Skyway.


Getting from A to B can be quite an undertaking. There are maps and signs in every building but how helpful are they and what does improving them mean?

Immediate Action Items:


  • Determine what content is most valuable
  • Go through agreements and add any additional buildings included
  • Get consistent photos for all skyway bridges
  • Compile information in a spreadsheet/database

Long-Term Action Items:

  • Redraw easements to modern technology standards (or submit a request that DSI do it?)
  • Obtain hi-res skway level building maps and integrate with bridges and access maps, creating a SUPERmap.
  • Add a comprehensive buildings section to the mix, including all spaces vacant and occupied.
  • Integrate database with comprehensive DtStP database.
