Neutral Ground

Median strip

A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas. The reserved area may simply be paved, but commonly it is adapted to other functions; for example, it may accommodate decorative landscaping, trees, a median barrier, or railway, rapid transit, light rail, or streetcar lines.

Neutral Ground (Louisiana)

The Neutral Ground was a disputed area between Spanish Texas and the United States' newly acquired Louisiana Purchase. Local officers of Spain and the United States agreed to leave the Neutral Ground temporarily outside the jurisdiction of either country. The area, now in western Louisiana, had neutral status from 1806 to 1821.
