Road ecology blog: The abandoned dirt road Estrada do Colono (- Settler's Road-), Parque Nacional do Iguaçu, Brazil
park across the river "Rio Iguaçu" that provided access to the road north of the river was blown up and sunk by law enforcement personnel.
Ideally, the roadbed, ditches and culverts should have been removed, and the soil should have been de-compacted. This would have allowed for a more rapid and natural direction of the succession, and it would have restored the hydrology. However, given the time passed since the most recent closure, the level of regrowth, and political sensitivities, it seems best to leave the situation as is rather than go in with heavy equipment.

Image below: a concrete culvert across a creek was never removed and now is in pieces in the creek bed.
