Repairing a cavernous underground culvert at Kidd Springs Park will cost about $208,000, and work is expected to begin this month.

We described that culvert, which has a natural limestone bottom and sides, as being built “many decades ago,” which admittedly was fudging. But it’s older than this enormous tunnel built in June 1930, according to this story from the Dallas Morning News Historical Archives.

It was built to drain more than 700 acres and was part of the city’s overall flood control plan, which was drawn up after the devastating flood of 1908. By 1930, the flood-control plan mostly was in place.
