Keystone Parkway Corridor

Carmel, Indiana

This project was a fast-track design of a four-lane expressway, including grade-separated, full-access, roundabout interchanges at six existing intersections along one of the most heavily traveled roadways in the city of Carmel. The planning portion of the project evaluated the feasibility of lowering portions of existing Keystone Avenue and determined the effects the project would have on adjacent properties. American Structurepoint evaluated the use of modern roundabouts in various configurations for the interchanges in lieu of tight diamonds or single-point interchanges. Land acquisition services included right-of-way engineering and acquisition of 41 parcels for five separate construction contracts.
