Death toll from Peru bus accident rises.

Peruvian rescue workers and investigators continued the arduous search for bodies and answers Wednesday at the grisly site where a tractor-trailer slammed into a bus on a stretch of mountain road known as “Devil’s Curve.”

The death toll rose to 51 people in Tuesday’s crash, authorities said. Six survivors were taken to hospitals.

Local Police Chief Víctor Rucoba said no highway signs in the area of Tuesday’s crash warned drivers of the perilous curve where the truck rammed the bus down a rocky cliff to a beach more than 260 feet below.

The wreck occurred in a remote area of Pasamayo, about 45 miles north of Lima. The two-lane, Pacific Ocean road — used only by trucks and buses — is considered one of the nation’s most dangerous. Transportation Minister Bruno Giuffra said buses could be banned from the section of road, and that plans are underway to build a third lane.

On Wednesday, workers sawed though the bus frame to extract bodies while heavy waves crashed on the beach around them. National Police Col. Dino Escudero Alcántara said the area was inaccessible by land, so emergency responders were helicoptered down to the site or arrived by boat. 

Teams picked their way along craggy rocks near the beach where the battered bus rested upside down. Some survivors and the bodies of victims were helicoptered out. A Peruvian navy ship assisted rescuers in the race to clear the scene ahead of the rising tides.

Police Col. Franklin Barreto said investigators were reviewing initial reports that both vehicles were traveling at a high rate of speed at the time of the crash. The driver of the truck was held for questioning, police said.
