The city announced Wednesday that work on the $2.7 million, 10-month project was finished on schedule and the Battery and the street nearby are again open.
The work consisted of restoring the High Battery sidewalk and seawall that is more than a century old and runs along the city's famed Rainbow Row.
The next phase of the project is engineering studies on repairing the Low Battery running almost a mile along the Ashley River on the other side of the peninsula.
The work is the latest in a series of renovations to city buildings and public spaces in Charleston that attracts 4 million visitors a year. In the past decade, almost $200 million worth of projects have been completed or are underway.
