SUCUSARI, Peru — It is the longest bridge ever built in Peru, a massive structure of concrete and iron spanning the Nanay River as it connects to untouched areas of the Peruvian Amazon.

So far, it goes nowhere.

The bridge is part of a federal highway project to connect Iquitos, in Peru’s northeast, to the El Estrecho district on the Colombia border, 117 miles in total. It faces mounting opposition from Indigenous people who fear that the construction will lead to land-grabbing, deforestation and drug trafficking, which have plagued similar projects across the world’s largest rainforest.

“The highway will kill us,” Everest Ochoa, a member of the Maijuna indigenous group that lives in the Peruvian Amazon, told The Associated Press. “We have to stop this project for the sake of our children, to protect the land for them.”

Construction work is at a standstill as the government conducts a study of the area, but the Ministry of Transportation has already built the country’s largest bridge, which extends 1.4 miles over the Nanay River, a tributary of the Amazon River.

Indigenous leaders say communities on the route haven’t been consulted.

“The government didn’t ask us anything about the highway passing through our territory, and we want our rights to be respected,” said community leader Artur Francis Cruz Ochoa.

His community, Nuevo Arenal, is next to the bridge and has suffered, he said.

“Drugs have already started to infiltrate our community, young people are already consuming them,” he said. “With the construction of the highway, it will get worse.”

In the village of Sucusari, also near the future path of the road, people echo those fears. It is a community of thatched houses, where the 180 inhabitants live a traditional lifestyle, fishing, hunting and growing fruit for local markets, mostly aguaje, an Amazon delicacy.

“We will lose land, animals, fish, the water will be contaminated, and the forest. If the forest is lost, we won’t have water. We won’t have life without water,” said Sebastian Rios Ochoa. “With the highway, the abundance we have now will end.”

In a written message to the AP, the Ministry of Transportation said the project’s objective is to connect people along the path and promote local economies, strengthen trade and help bring security to border areas.

The ministry said the construction of the bridge is considered an infrastructure project for public services and, as such, is not required to undergo prior consultation with the Indigenous tribes, according to Peru’s legislation.

The Iquitos-El Estrecho is the largest and most expensive highway construction in Peru’s Amazon, according to a recent report by Peruvian Society of Environmental Law, a nonprofit. The report cites land-grabbing and deforestation in Indigenous lands. The highway will cross two protected areas, Maijuna Kichwa and Ampiyacu Apayacu, which cover about 3,000 square miles of old-growth forest.
