The fire began with a series of blasts and engulfed the pier, destroying the structure Two teenagers who were arrested on suspicion of arson after a huge fire on Hastings Pier have been bailed.
Firefighters also remain at the scene damping down more than 24 hours after the fire started at the historic structure in East Sussex.
Up to 95% of the pier has been destroyed and Hastings council has warned the pier is at risk of collapsing into the sea.
It warned people to keep away from the pier, which is in a dangerous state.
Road closures remained in place on Wednesday morning, around the A259 area.
In a statement, the council said: “The pier remains in a very dangerous state and people are advised to stay well away from it as the risk of collapse is high.
“Under no circumstances should people attempt to gain access under the pier at this time.”
Two men, aged 18 and 19 and from St Leonards, were arrested and detained for questioning on Tuesday as crews fought the flames on the pier, which was already closed for safety reasons.
A spokesman for Sussex Police confirmed early on Wednesday that both teenagers had been bailed.

The alert came in the early hours of Tuesday after a member of the public alerted police officers on patrol to a fire on the pier.
Nearby residents also reported hearing a series of explosions in the early hours.
Within a short time, the entire structure was engulfed in flames.
Emergency crews on the scene described seeing a plume of thick, acrid smoke and the historic ballroom reduced to a burning framework, with bits falling into the sea.
At the height of the incident, about 55 firefighters were at the scene.
The fire was brought under control by 0800 BST on Tuesday, with no reports of any injuries, but the pier continued to burn and smoulder.
The pier had been closed since 2006 because of fears it was unsafe After the fire, campaigners who had wanted to restore the derelict pier said they were still hopeful that it could be salvaged.
Earlier this year, the council agreed to buy the pier with a compulsory purchase order and hand it to the Hastings Pier and White Rock Trust.
Jess Steele, the trust’s treasurer, said: “This tragedy has further galvanized public support for securing the future of this much-loved pier.
“If the survey shows that the substructure is reusable we will do our utmost to bring this great asset back to life.”
The pier opened in 1872 and was originally 910ft (280m) long. It closed in 2006 because of fears it had become unsafe.
It was owned by Panamanian-registered company Ravenclaw, which the council said it had been unable to contact.
Campaigners have also been writing about their shock and disbelief on the Facebook page, Save Hastings Pier, which has more than 1,600 members.
