HUNTINGTON — Nearly 20 employees from the Rahall Transportation Institute and the Marshall University Center for Business and Economic Research left the office Friday morning to grab paint brushes and trash bags to do some summer sprucing. Their goal was to touch up the Paul Ambrose Trail for Health mural located at the 10th Street underpass and clean trash and debris from the area. Employees from RTI and Bulldog Creative Services were the primary painters of the mural in 2011, and Emily Hagan, marketing programs project specialist for RTI, said getting volunteers to come out and maintain it has never been a problem. “So far we have come out once a year to maintain the area,” Hagan said. “We don’t want to just come out one time, do a project and leave it alone. We want it to stay looking nice for the city.” Hagan said the underpass is a direct gateway connecting downtown Huntington with Ritter Park. She said she was surprised when she first realized how many people use the walkway for exercise or going from one place to another. Amanda Payne, trails program manager, said as a Huntington resident she is happy to take part in helping the city look nice. “In college I just lived a few blocks from here, and it’s interesting to see the change this mural and the PATH have made,” Payne said. “I run here and used to walk this way to go to work, and it’s much nicer than just a plain wall.” The Paul Ambrose Trail for Health (PATH) is a bicycle and pedestrian trail system that provides free, healthy recreational opportunities for Huntington and surrounding areas. Hagan said reception of the initiative has been outstanding the past few years, and multiple cities have contacted RTI to inquire how they can replicate the PATH project.
