Know before you cross
- On foot: This port has a pedestrian crossing; the live table above shows the current wait on foot.
- SENTRI / Ready Lane: SENTRI members get a dedicated vehicle lane here and the Ready Lane accepts RFID-chipped documents (passport card, green cards issued since 2010, border crossing cards). See lane types explained.
- Documents: US citizens need a passport, passport card, or enhanced driver’s license; green-card holders show the green card; visa holders need passport + visa and should check their I-94 record after every entry. Full detail in the documents-to-cross guide.
