Sections of Duque de Caxias and Brigadeiro Protásio will be closed for drainage work advancement in Belém
Interventions by Seop are part of the investments by the Government of Pará for COP30 and will continue until the end of September

The Government of the State of Pará, through the State Secretariat of Public Works (Seop), will begin on Wednesday (17) the closure of sections of Duque de Caxias and Brigadeiro Protásio Avenues in Belém for the advancement of deep drainage works. The interventions are part of the structural investments aimed at hosting the 30th United Nations Conference on Climate Change (COP30), which will be held in November in the capital of Pará.
The traffic blockages will start at 8 AM and will continue until the end of September, aiming to ensure the safety of workers, pedestrians, and drivers, as well as to ensure the proper execution of the works.
Understand the closure points
During the construction period:
- The Brigadeiro Protásio Avenue will have traffic interrupted in the direction of Av. Dr. Freitas → Av. Júlio César;
- On Duque de Caxias Avenue, traffic will be closed between Travessa Perebebuí and Av. Dr. Freitas, in the direction of Hangar – Amazon Convention and Exhibition Center.
Note: It is recommended that drivers seek alternative routes and pay extra attention in the area.
Deep drainage works in the Marco neighborhood
The interventions are taking place at strategic points in the Marco and Souza neighborhoods, covering the intersections of Dr. Freitas, Brigadeiro Protásio, Boulevard, and Duque de Caxias Avenues. According to Seop, the work is essential to enhance the efficiency of stormwater drainage, prevent flooding, avoid damage to road structures, and improve urban traffic conditions.

The drainage is being executed using shoring techniques to ensure the structural safety of adjacent areas. High-Density Polyethylene (HDPE) pipes are being installed, which have greater resistance to corrosion and superior flow capacity, in addition to the installation of access wells and inspection boxes, which will facilitate future maintenance.
The new networks will be integrated into the existing systems, ensuring hydraulic continuity and eliminating critical points of retention or backflow. After the completion of the drainage services, the asphalt and sidewalks in the affected sections will be restored.
