The Big Dig was completed five years ago, resulting in the Central Artery’s demolition and creation of the Rose Fitzgerald Kennedy Greenway, 15 acres of public land. Once-polluted Boston Harbor has become not only a chic dining destination but clean enough to swim in.

For many Bostonians, though, the waterfront neighborhood and Greenway remain terra incognita. How to lure them down there? That is the aim of a consortium of nonprofit organizations, governmental agencies, and business owners behind a campaign labeled “Summer on the Waterfront: Eat, Splash, Shop, Learn.’’ Backed by a six-figure marketing effort, it will be formally unveiled June 1 and celebrated with a kickoff ceremony June 2 on the Greenway. The campaign runs through Labor Day.

Along with a dedicated website (www.summeronthewaterfront.org) and a packed schedule of events, it will feature outdoor concerts, architectural tours, and the opening of two new visitor centers, in Faneuil Hall and on Peddocks Island in Boston Harbor; educational programs and family activities, from harbor island excursions to scavenger hunts, highlighting Boston’s storied history. And a smartphone app will enable visitors to shop at scores of merchants without needing cash or credit cards.

“This is the engineers finally passing the baton to the creative folks and retailers,’’ said Julie Wormser, executive director of the Boston Harbor Association, who helped brainstorm the campaign. After a $22 billion, multiyear investment in the city’s infrastructure that created years of traffic snarls, construction noise, and other headaches, residents and tourists will get to enjoy the fruits of Boston’s recent transformation.
