Was reading through another thread and was intrigued by how NY 189 is a one-way border crossing in that you can enter the US from Canada, but as Canada closed their customs station you cannot enter Canada at that crossing. How many others are there like this? It can be US-Canada, US-Mexico, or other countries.
The Paseo del Norte in El Paso is only open to vehicles coming into the US, as the bridge is one-way. However pedestrian crossing is two-way. The next crossing down, at Stanton Street, is only open northbound to SENTRI vehicles.
