The Fourth of July fireworks show at Fort Vancouver will be free this year.

The Fort Vancouver National Trust, which presents the annual July 4 display, announced Friday that there will be no admission charge for the event.

In another format change, the event — which has been a daylong affair in previous years — will be all about the fireworks, said Mike True, president and CEO of the National Trust.

The program will start at 6 p.m. with live music, leading up to the 10 p.m. pyrotechnic display.

The event is officially known as Independence Day at Fort Vancouver presented by Bank of America.
