When Reid Harper remembers his father, Bob, he thinks of a man who "did what needed to be done." 

And that's how community members remembered the late Robert Harper Friday morning at the Moon Municipal Building -- as a man who served as an advocate for the township.  Harper died in 2010 at the age of 63. 

The interchange of Thorn Run Road and the Interstate 376 Business Loop was dedicated to Harper today, and the Pennsylvania Department of Transportation will soon install a new sign at the junction bearing his name. The state General Assembly passed legislation to rename the intersection in October. 

Friends, family, residents and public officials were on hand for the dedication ceremony. 

"He was a problem solver in the community," Harper said. "[The dedication] was unexpected and certainly humbling. It's nice that they're honoring him this way." 

Harper served as a Moon supervisor from 1980 to 1983 and worked to bring infrastructure and transportation improvements to the township. He was a 1964 graduate of the former Coraopolis High School.

Pennsylvania State Representative Mark Mustio described Harper as "a wonderful, wonderful man." 

"I can't think of a more appropriate way to honor Bob," Mustio said. "Every time there was an issue in Moon, he would call. He was an integral part of the community." 

Harper was also a lifelong member of the Coraopolis United Methodist Church. Check out a video of a musical ensemble from the church, the Robert E. Harper Men's Chorus, performing at the ceremony.
