Perryville Rd. & Swanson Rd.
Winnebago County, IL
MTJ Engineering provided the Roundabout Analysis, Design, and IDS data for this interim single lane and ultimate dual lane roundabout with a future planned fourth leg. It is located at the intersection of CH 11 (Perryville Rd.) and CH 87 (Swanson Rd).
This challenging interim and ultimate design was developed to provide optimal safety for the near term traffic demand while allowing for easy future expansion when traffic demand warrants the additional capacity.
