In 1997 Canal Corridor Association hired a full-time historian in order to further the goal of providing high quality interpretation for visitors to the corridor. Since then CCA has developed an extensive series of outdoor interpretive exhibits in the I&M Corridor. The I&M Canal Passage Wayfinding System consists of trail entry signs and maps, mile markers, and Cor-Ten steel silhouettes of real individuals.
A wayfinding system throughout the National Heritage Corridor was established in 2002. Milemarker signs at each mile give a fun fact about the canal. Kiosks let trail travelers know of the attractions near that trailhead. Cantilever signs interpret major stories along the canal. The wayfinding signs add an element of interpretation and interaction between the trail, its history, and its users. The 2002 interpretive signage along the canal trails is being updated in 2017 by Cardosi Kiper Design with a new look, updated information, and a QR code to link the sign to an application with more information on the subject, as well as what attractions are nearby. This will enhance the trail experience and provide a more interactive experience for trail
