British Virgin Islands has received a $45 million loan from Banco Popular of Puerto Rico to help expand the territory’s only public hospital and update the sewage system.

Finance Secretary Neil Smith says it is the most complex project the government has tackled in recent history. The existing Peebles Hospital is based in Tortola and has more than 40 beds.

Smith says $30 million will go toward the expansion, while the remainder of the loan will be used to update the island’s sewage system.
