Disneyland park has announced more details and updates the status of Project Stardust:

In addition to enhancing curbs with slow inclines, we are softening corners on planters to help guests navigate around them.

We also will be working on the entrance and marquee to Adventureland as part of Project Stardust. We will temporarily take the marquee down to remove a walkway support for ease of guest flow.

When Project Stardust is complete, Disneyland park will remain the beloved icon and international treasure it is today, while preparing the Disneyland Resort for generations of future guests.
