Strongly interacting galaxy pairs provide a basis for studies of tidal bridges. Moderately deep, multi-color optical images were obtained with the WIYN 0.9-m telescope for a variety of systems with stellar tidal bridges. The bridges in these systems range from having complex structures with evidence for star formation to extremely smooth and extended, as in Arp 104. Photometric measurements quantify the amplitudes of the structural elements within these features and provide a basis for comparisons with tidal bridge formation models. The bridge structures and colors also yield insights into the importance of star formation within these low density regions.
