Investigation teams will no longer be at a secondary scene of the Haut Du Mont disaster.
The Senior Investigating Officer for Operation Spire says a police presence is no longer required between Commercial Building and Le Quai Aux Marchands.
It has been part of the ongoing investigation since the 10 December explosion that claimed the live of 10 islanders.
Specialist Urban Search and Rescue teams will be returning to the UK this week too.
The Senior Investigating Officer for Operation Spire, Detective Superintendent Alison Fossey, says teams are continuing to make good progress in the investigation.
"I’d like to thank the USAR teams for their hard work and Fire and Rescue National Resilience for coordinating their deployment to Jersey."
"USAR have been a vital part of the response in working with our local emergency services to facilitate the ongoing response, and their specialist skills and professionalism has been second to none."
The main scene at Haut du Mont on Pier Road is still under investigation and will be 'for some time'.
More than 30 officers continue to work on the case.
"To date, our teams are following 601 lines of enquiry, have taken 230 statements and have recovered 490 exhibits."
Detective Superintendent Fossey says efforts remain focused on doing the best for grieving relatives and the displaced residents.
"Our Family Liaison Officers are supporting the bereaved families and community police are meeting regularly with the displaced residents. Funerals continue to take place this week, and our thoughts remain with families and friends at this difficult time.”
