Toyo Tunnel

WSP contributed its experience to the largest tunnel project in America part of the megaproject of 18 tunnels, 30 bridges and 17 kilometers of open-air roads in Colombia.

Location

  • Antioquia, Colombia

Client

  • Government of Antioquia/Antioquia al Mar Consortium

The Guillermo Gaviria Echeverri Tunnel, also known as the Toyo Tunnel, constitutes a notable infrastructure project in Colombia, located in the northwest region of the country. This project covers a corridor of 18.3 kilometers, which begins in the municipality of Cañasgordas (Antioquia) and ends in the municipality of Giraldo (Antioquia).

The fundamental purpose of this road project is to improve connectivity and road infrastructure in the region. The Toyo tunnel stands out thanks to its length of 9,730 meters, making it the longest tunnel in America and the deepest at 900 meters below the profile of the mountain.

WSP, with its extensive global experience, played a fundamental role in this project by carrying out the final studies and designs in Phase III for Section No. 1.

From WSP in Colombia, the activities developed by the Transportation and Infrastructure team were:

  • Transportation study
  • Geometric layout and design study
  • Engineering geology
  • Soil study for the design of bridge foundations and other retaining structures
  • Slope stability and stabilization study
  • Geotechnical study and pavement design
  • Study of hydrology, hydraulics and scour
  • Study and design of structures
  • Tunnel study and designs
  • Urban planning and landscaping study
  • Study of work quantities, analysis of unit prices and budget for structuring the specifications
  • Socioeconomic evaluation of the project
  • Executive final report

The Earth & Environment team took part in the following activities as part of the Comprehensive Property Management (social, technical, and legal) of Section No. 2 of the project:

  • Preliminary identification of the study area
  • Verification and comparison of cadastral and municipal databases
  • Field activities for verification
  • Review of the POT, PBOT or EOT (land-use plan, basic land-use plan or land-use schema)
  • Legal technical diagnosis
  • Property recognition
  • Preparation of property files, plans and inventories
  • Preparation of socio-property files and compensations
  • Project socialization meetings from the point of view of property impacts
  • Title study
  • Preparation of property sheets

Additionally, during Phase I, the structural and hydrosanitary designs of the architectural modification made to the new buildings planned for the main Operational Control Center in K37+185 of the Antioquia al Mar Consortium were carried out.
