PROJECT OVERVIEW

This Complete Streets project includes a 1.5-mile reconstruction of TH 87 in Frazee, Minnesota to accommodate a shared use path, walk, parking, and driving lanes. Isthmus led the preliminary design for this project, which included the development of a Level 1 Geometric Layout, and is currently leading the ADA design and 3D modeling for the detailed design effort.

Isthmus used the PowerGeopak Civil Modeling tools throughout the preliminary design process to develop the alternative alignment shifts under consideration. In addition, the modeling tools were used to design the ADA intersections, develop the centerline profile, and to support the Isthmus visualization efforts on this project.

The Isthmus-prepared visualizations include renderings of each segment’s alternatives, 3D photospheres, and a video fly-through which were successfully used to inform the public and stakeholders of the potential options and impacts, receive feedback, and move the project forward. An internal Isthmus-developed process allowed for these visualizations to be updated with little additional effort as the design work progressed.

As a part of this project, Isthmus has provided over the shoulder support to District 4 in the use of the PowerGeopak Civil Design tools.
