The National Department of Transport Infrastructure (DNIT) has initiated the emergency construction of a new bridge over the Tocantins River, on BR-226, between Maranhão and Tocantins. The project connects the municipalities of Aguiarnópolis (TO) and Estreito (MA) and has an estimated completion time of one year.
Investment And Characteristics Of The New Bridge

With a diameter of 15.08 meters, a length of 182 meters, and weighing 3900 tons, the world’s largest tunnel boring machine for drilling super hard rock made a 9 km tunnel in Georgia and impresses with its excavation power.

Buried house on Greek island uses stone, concrete, wood, and glass to appear as part of the rock, according to MOLD Architects, while movable facades, internal courtyards, and pergolas bring air, shade, and light to the spaces hidden in the hillside.

Concrete thrown away can turn into money on the construction site itself and sell aggregate by the ton, according to a technical survey on mobile crushing that transforms debris into business for construction companies attentive to heavy costs.
The crossing will feature two traffic lanes of 3.6 meters each, two three-meter shoulders, New Jersey-type safety barriers, two sidewalks for pedestrians, and guardrails at each end of the deck.

Progress Of The Work
The initial phase is already underway, with the mechanized removal of the debris from the old Juscelino Kubitschek de Oliveira bridge.
The teams have begun mechanized excavations for the implementation of the foundations of the supports on the Estreito municipality side.
Work is also ongoing for the installation of the construction site and the mobilization of equipment and personnel.
The foundation footings will be concreted on-site, and then the pillars will be erected. With these stages in progress, DNIT is following the established schedule, with a forecast for the delivery of the new bridge by the end of the year.
The Collapse Of The Old Bridge
The Juscelino Kubitschek de Oliveira Bridge collapsed on December 22, 2024, causing a tragedy.
The structure, with a length of 533 meters, gave way around 2:50 PM, resulting in the fall of several vehicles, including trucks, cars, and motorcycles, into the Tocantins River.
Inaugurated in 1961, the bridge was an essential route connecting Maranhão and Tocantins, integrating BR-226 and BR-230 highways.
Prior to the collapse, reports indicated signs of wear in the structure, and there were plans for its renovation that were not realized in time.
