A concrete truck will transport concrete forms from the Vatican to the site of the church in the capital of Vatican City.
Construction is underway at the building in the city’s southern suburb of Santa Croce.
It was originally planned to be completed in 2020, but has now been delayed by a lack of funding, which has also resulted in some delays in construction.
The project will cost between $1 billion and $2 billion, according to local media reports.
Construction began in early April, with the first concrete form being laid by the end of this month.
Construction was due to be complete by July, but a number of delays in the construction have caused the project to take longer to complete than planned.
The truck will take a minimum of three months to deliver the concrete forms to the Vatican, with a maximum of four months for the final delivery, said the project’s head, Father Federico Lombardi.
