Coloring Outside of the Line

Not our typical type of job, but we’re really proud to have contributed interpretive and environmental design expertise to the Mason-Dixon/Arc Corner Heritage Interpretation and Connectivity Plan!


The team at Miller Designworks helped shape a Mason-Dixon/Arc Corner Identity as well as create a unified story-telling framework that connects history, heritage, landscape, science, and community across township lines.

From site analysis and 3D LIDAR scanning to interpretive design and wayfinding recommendations, we worked with a task force of contributing consultants led by the Brandywine Conservancy. The goal was to develop a strategic roadmap that will strengthen visitor experience, improve connectivity, and honor one of America’s most iconic historic boundaries.


It was exciting to get to do the site visits and see actual Mason Dixon markers along the line, including a crown marker indicating a five-mile point on the line. The science involved and the sheer force of will it took to complete this survey task was impressive to learn about, and we are fortunate to have the results of it right in our backyard.

This project isn’t just about signage and graphic panels; it’s about creating a shared identity and a cohesive heritage experience that communities can build on for generations.

We’re excited to see this vision move toward implementation in the contributing Chester County townships!
