Rio Grande City's crossing is the
Starr-Camargo Bridge. Los Ebanos is 20 miles away, and I would consider to be part/near La Joya. The latest numbers I can find are from 2018, where there about 60,000 crossings a year, split roughly in half between pedestrians and vehicles. The Starr-Camargo bridge gets 400,000 crossings per year. Most folks in the Rio Grande Valley cross at the Pharr, McAllen, and Brownsville bridges at several million per year
Then there's the "Your neighbor is on the other side of the street AND border".
