The ribbon was cut to officially open Sun Valley Co-op's new gas bar in Altona.

Sun Valley is marking its 75th anniversary this year.

General manager Brian Enns says that 75 years of history has been built through the support of its members and the community.

Enns adds the three year process of constructing the gas bar facility was an interesting one and hopes Altona looks to Co-op as a community builder for many years to come.
