Bicentennial Roundabout Underpass – Guadalupe
(Completed)
ABOUT THE PROJECT
Construction of the new underpass at the Guadalupe signalized intersection began in January 2020 and was completed in 2021. This project connects with the Circunvalacion Norte Road highway. The underground passage is 790 meters long and includes four lanes in the underpass (two in each direction). A roundabout with two lanes in each direction was also built to provide access to surrounding communities. In addition, sidewalks on both sides, bus bays, a pedestrian bridge, and an expanded culvert over the Torres River were constructed.
The project is part of a broader initiative aimed at developing three underpasses along Ring Road Route 39, beneath the Garantías Sociales and La Bandera roundabouts, and the Guadalupe intersection (where the roundabout was built above the underpass).
Route 39, also known as Circunvalacion Norte, is one of the main traffic arteries of Costa Rica’s capital city. The underpasses will improve traffic flow throughout the area, where more than 70,000 vehicles circulate daily.
UNOPS' ROLE
Project management under a full implementation modality.
UNOPS acted as the implementing agency responsible for the procurement and auditing of construction works, as well as project supervision. The physical measurement auditing process allowed oversight of both the contractor’s and the supervisor’s work. UNOPS also carried out the project’s social management component and strengthened the capacities of the CONAVI-CABEI Executing Unit, particularly in construction oversight.
