Infrastructure Evolution
A Logistics System in Transition
Manzanillo's infrastructure system is undergoing a series of road, access and port-related interventions that are changing the physical environment around the gateway. These projects range from corridor modernization and access improvements to longer-term port development initiatives.
Road and port-access projects are currently modifying key physical connections around Manzanillo.
Several interventions are already under execution, while others remain at planning, contracting or environmental-review stages.
The emerging infrastructure layer should be understood as a portfolio of projects at different stages rather than as a single completed transformation.

Infrastructure Overview
Infrastructure Overview
What Is Being Changed
Current infrastructure initiatives affect several layers of the physical system around Manzanillo, from major road corridors and port-access infrastructure to longer-term port development.
Road Corridors
Major road corridors are being modernized or expanded to modify existing terrestrial connections around Manzanillo.
Port Access
Interchanges, approaches and access works are being developed to modify the physical interface between the inland network and the port gateway.
Bridges and Interchanges
New and upgraded structures form part of current infrastructure programs addressing specific access and corridor constraints around Manzanillo.
Port Development
Longer-term initiatives such as Nuevo Manzanillo Cuyutlán represent a separate layer of potential port infrastructure expansion beyond the existing system.
Transportation Network

Changing the Connections Around the Gateway
Infrastructure projects are not isolated assets. Their relevance to the physical network comes from the connections they modify between Manzanillo, port-access routes and the wider inland transportation system.
01
Corridor Modernization
The Armería–Manzanillo modernization is modifying an existing road connection through corridor rehabilitation, lane expansion, structures and interchanges.
02
Port-Access Improvements
Projects around Jalipa, Minatitlán and other access points are aimed at modifying the physical connections used to reach the port environment.
03
Bridge and Interchange Connections
New structures and interchanges address specific points within the road-access system and can alter how local and regional infrastructure interfaces with the gateway.
04
Road and Rail Interface
Some current access initiatives involve areas where road and rail infrastructure interact, reinforcing the importance of multimodal interfaces within the evolving physical system.
Strategic Projects
Strategic Projects
A Portfolio of Infrastructure Interventions
Manzanillo's infrastructure pipeline includes projects at different stages of execution, contracting and development. Together they illustrate how the physical system is being modified across roads, access infrastructure and the port environment.
Armería–Manzanillo Modernization
A 52-kilometer modernization program that includes expansion from four to six lanes, structures and interchanges. SICT reported 40% progress in March 2026, with completion planned for December 2026.
Libramiento Manzanillo Expansion
An expansion of the Manzanillo bypass from two to four lanes, forming part of the current infrastructure program around the gateway.
Jalipa and Minatitlán Interchanges
Access infrastructure projects intended to improve the physical connection between the road network and the port environment.
Nuevo Manzanillo Cuyutlán
A long-term port development initiative involving new port infrastructure and associated road and rail connectivity. Its development has included environmental-review processes and should not be treated as completed infrastructure.
Development Priorities
Development Priorities
Four Recurring Infrastructure Priorities
Across current infrastructure programs, several recurring priorities emerge from the type of interventions being developed around Manzanillo.
Corridor Capacity
Expanding or modernizing major road corridors is a recurring component of current infrastructure programs.
Strategic Focus
Road capacity
Port Access
Interchanges, approaches and access works focus on improving the physical interface between the inland network and the port environment.
Strategic Focus
Gateway access
Multimodal Connectivity
Road and rail interfaces are part of the infrastructure environment surrounding the gateway and feature in longer-term development initiatives.
Strategic Focus
Road and rail
Regional Integration
Several interventions operate beyond the immediate port perimeter, modifying connections between Manzanillo and the wider regional transportation system.

Future Development
An Infrastructure System at Different Stages
The future infrastructure landscape around Manzanillo is not a single project pipeline. It includes active construction, contracted works, projects under development and longer-term initiatives whose execution depends on subsequent stages of planning and approval.
Projects Under Execution
Current road and access works are already modifying parts of the existing infrastructure system and have defined construction schedules.
Projects Under Development
Other interventions are moving through contracting, planning or implementation stages and may progressively alter the physical network.
Long-Term Port Development
Nuevo Manzanillo Cuyutlán represents a longer-term infrastructure initiative whose scale extends beyond the current port-access system and includes planned road and rail connections.
An Evolving Physical Layer
The combined project portfolio suggests that Manzanillo's infrastructure should be monitored as a changing physical system rather than treated as a fixed network.
Conclusion
Key Insight
Infrastructure Evolution Is a Process, Not a Single Project
Manzanillo's infrastructure is evolving through a portfolio of interventions that operate at different scales and stages. Road corridor modernization, port-access improvements and longer-term port development are changing different parts of the physical system. The key distinction is not simply what is planned, but what has been contracted, what is under execution and what remains under development. Together, these projects provide the clearest view of how the infrastructure layer around Manzanillo may change over time.
