 These improvements now enable continuous road travel and the shipment of goods overland between ports in Brazil and ports in Peru.The full effects of the highway have not yet been experienced, because the highway was only completed in 2011, but portions of the lower and middle Las Piedras are now under increased threat of deforestation.This conclusion is based on the fact that across the border in Acre, Brazil the paved highway affects the forests 45 km from the highway  and there are points where the lower and middle Piedras are within 30 km of the highway.
