NCDOT conducted a study to replace an S-shaped swing-span bridge over the Perquimans River in Hertford, NC. The existing bridge is eligible for the National Register of Historic Places (NRHP), and terminates in a NRHP historic district. Alternatives were considered that replaced the bridge with a similar-type facility, a higher fixed bridge on a similar alignment, and an alternative that avoided the historic district. A majority of the community was initially concerned about a higher bridge. Through the use of 3D photo renderings from multiple angles, the community was able to visualize the alternative which notably increased support for that alternative (which was eventually selected as the preferred alternative). To obtain appropriate high-resolution photographs, we contracted Sky Site to take photos from a low-flying helicopter and using an elevated camera from ground level.
