The 40 metres Haumu bridge was constructed at a cost of K700,000.
Minister Nali when addressing the people at the opening urged the people to take care of such infrastructures and take responsibility to own it.
"The Government will always provide services but all it is asking for is for people to take ownership and look after it."
Speaking as the Alotau MP, Mr Abel said such infrastructures are important for the Government as it opens up opportunities for people to take part in doing business and other commercial activities.
He said the Government always and will be always in the forefront in bringing services to the people.
He added that the Government is planning to connect all the missing links in the country and Port Moresby to Alotau is one of them.
