Workers were hoisted into the air on large orange cranes Tuesday afternoon so they could slather the final layers of primer onto the side of an air intake building in Dewey Square.

The crews weren’t giving the building a new paint job. Instead they were prepping what’s become a large outdoor canvas reserved for temporary artwork commissioned by the Rose Kennedy Greenway Conservancy and local museums.

A mural by conceptual artist Lawrence Weiner, called “A Translation from One Language to Another,” will materialize on the building’s side in the next few days.

The conservancy partnered with the MIT List Visual Arts Center to bring the new mural to what’s known as the Greenway Wall, which towers over Dewey Square Park, just across the street from South Station.


Weiner’s work will feature bold text, as opposed to the abstract paintings that have been on the wall before.

Painters from Overall Murals, a New York City-based outdoor advertising firm that specializes in hand-painted displays, will install Weiner’s work, now that the primer is set, using 25 gallons of paint.

Conservancy spokesman Michael Nichols said they are not releasing any hints about what the language on the wall will say.

“It’s a new design for the Greenway with a phrase that [Weiner] has used before,” he said. “It will be very different for Boston, and we hope it starts a new conversation about the types of art you see in Boston.”

The latest installation marks the fourth time that temporary public artwork will be splashed onto the Greenway Wall.

Weiner’s mural will replace Shinique Smith’s “Seven Moon Junction.”

An opening reception and public celebration, where visitors can meet Weiner and enjoy live music by students from Berklee College of Music, will be held in front of the newest installation on Sept. 24, Nichols said.
