Did you know that the National Park Service controls the land under the I-70 depressed lanes? That's one of the things involved with any changes to Memorial Drive, the depressed lanes, or the Arch grounds. It's all under the control of the National Park Service.
Yesterday, the National Park Service announced that it will revisit the "management plan" for the Arch, a document that dates back over 40 years. A lot has changed in 40 years, so the National Park Service has decided to engage the public in a discussion about how to position the Arch and its surroundings for the next generation or two.
One suggestion is to build a "walkway" over Memorial Drive, however, the idea of ceding land from the NPS to the City of St. Louis or some other local authority was not expressly mentioned as part of the agenda.
It will be interesting to see how much is available for review and discussion, but the good news is that this is a start. The timeframe for receiving public input is estimated at 18 months.
