The new proposal gets around that problem in a novel way: by changing the boundaries of the park itself. The new road would have shifted the northeastern park boundary to the west to make room for the toll road, then added acreage to the park’s southern section — overall, a net gain of about 14 acres for the park, which is leased to the state by the Navy.
