When Phase 2 is complete, the highway will be 5 to 20 feet off the surrounding ground. The highest elevations (around 17-20 feet) will occur at overpasses such as Cherry Lane and McMIllan Road. In these locations, SH-16 will cross over the local roads.
In Phase 3, the highway elevation will be raised at each future interchange location (Franklin Road, Ustick Road, US-20/26 and SH-44). Elevated flyover ramps – up to 50 feet in elevation — will also be constructed at the I-84 interchange in Phase 3.
