Renewed efforts are underway to construct barriers along the US-Mexico border. Certain areas, previously without such structures, are now being targeted. A region of interest is home to national and state parks. Despite historically low crossing numbers, infrastructure plans are moving forward. Concerns have been raised by residents and environmentalists.

Further information is available on the specifics of these plans. Contracts worth billions of dollars have been awarded for the project. Details on the exact nature of the infrastructure are not fully clear.
