Despite this morning’s rainfall, a new sculpture was being installed in downtown Lawrence in honor of the city’s 150th birthday anniversary.

The sculpture, “Freeform,” created by Stephen Johnson, was being installed this morning by a crane at the southwest corner of the intersection of Sixth and Massachusetts streets, across from city hall. The 10-foot-tall painted steel scultpure rests on a two-foot limestone base.

“The Lawrence Arts Commission commissioned the project in 2004 as part of the city’s 150th anniversary celebration. This is the completion of work that was started over a year ago,” said Lisa Patterson, the city’s communications manager.

The official unveiling of the artwork is scheduled for 11:30 a.m. Thursday, Patterson said. The project was budgeted at $53,000.
