Starting Friday, pedestrians and cyclists (ok, fine, rollerbladers, too) will have a new way to get from Charlestown to Cambridge, without hopping in their car.

State officials from the Department of Conservation and Recreation, as well as Governor Deval Patrick, will celebrate the opening of the North Bank Bridge, a strip of walkway connecting East Cambridge to the Charlestown City Square and the Boston Harbor Waterfront.

Patrick and MassDOT Secretary Rich Davey will celebrate on the Cambridge end during the ribbon cutting ceremony, and on the Charlestown side of the new bridge, the Charlestown Waterfront Coalition, and the Friends of City Square Park will be hosting a celebration at the Paul Revere Park.

There will be free ice cream and drinks.

According to MassDOT, the project completes surface restoration beneath and adjacent to the Zakim Bridge along the north and south banks of the Charles River “and offers an enhanced route for residents traveling to the Charlestown waterfront and North End.”

The nearly-698-foot steel structure winds over a pair of Commuter Rail tracks and looks a little bit like a rollercoaster.

Wendy Landman, Executive Director of Walk Boston, a non-profit membership organization dedicated to improving walking conditions in cities and towns across Massachusetts, called it “a fantastic project.”

“It creates a connector…which opens up a whole new piece of riverfront in a lot of ways. There has been this dead end park system and by connecting the two, it creates a fantastic linear path along the Charles,” she said.

The roughly $25.3 million project was paid for with federal stimulus dollars awarded through the American Recovery and Reinvestment Act, according to a MassDOT spokeswoman.

When the project broke ground, MassaDOT officials said the building of the bridge created jobs in the “construction trades for ironworkers, electricians, masons, surveyors, and laborers as well as fabricators and engineering professionals.”
