Our impact

Port of Miami Tunnel, Florida, USA

A Major road tunnel under the Port of Miami feeding one of the largest cruise port terminal and relieving the city center road network. In operation since 2014.




Construction of the Port of Miami Tunnel Project has provided a direct high capacity road link between the Miami seaport and Florida’s arterial highway network. The new infrastructure connection immediately diverted around 16,000 vehicles of daily traffic, much of it heavy trucks, from downtown Miami, reducing congestion, improving quality of life and aiding future development in the area.

Simultaneously, the twin-tunnel and highway improvement has boosted the operations and competitiveness of the Port of Miami. In 2014, following completion of construction of the tunnel, Meridiam and Bouygues Construction signed a SPA under which Meridiam acquired Bouygues
Construction’s stake (6.6%) in the Project Company.

ESG/SDG Key Facts


The Project features flood gates that protect the tunnel against flooding which mitigates risks related to sea level rise and climate change.
It is estimated that 80% of the cargo traffic travelling in and out of the Port of Miami is using the tunnel, thereby avoiding the downtown areas and noticeably increasing quality of life for residents, while decreasing carbon emissions from congestion and idle time on city streets.
Energy conservation initiatives are ongoing. Building lighting was converted to LED in 2020 and the conversion for driveway and parking lot lighting was completed in Q4 2020. Tunnel roadway LED lighting was installed in Q4 2021. The Project is involved with Port of Miami and Miami-Dade County’s #Resilient305 strategy with the launch of COOL (CO2 Lowering) to reduce CO2 emissions at the port from all partners.
In Q2 2022, the Project received the Corporate Business of the Year Award, and the Project Company’s COO Wendy Conforme was awarded at the 2022 International Women’s Day Achievement Awards at the Miami World Trade Centre. In Q2 2023, Wendy Conforme was promoted to CEO, as envisaged in the succession plan, with the former CEO remaining involved as Chair of the Board.
