“Usual” is the average over the last 30 days; where it says CBP, it’s CBP’s own published average for October, from the year before, because there aren’t enough readings here yet. NEXUS is CBP’s trusted-traveler lane; the Ready Lane is for travelers carrying an RFID-enabled document (a passport card, a border crossing card, an enhanced driver’s license). First reading on record: Sep 14, 2026.

A dot is an hour with no readings: the lane was closed or CBP posted no wait. A closed lane counts as unknown, not as zero, so it never makes a crossing look faster than it is. Average over the last 30 days: 7 min, from 408 readings.

About these numbers

Copied Oct 30, 2026, 7:48 AM Michigan time

Officers at each port of entry post every lane’s wait about once an hour to CBP’s Border Wait Times system. A small Cloudflare Worker reads it every half hour and keeps each reading once; the last-30-days averages come from that record. The averages from the year before are CBP’s own.

Times are the crossing’s local time. A closed lane or a pending reading counts as unknown, never as zero. The board has every crossing right now and how it all works, and the data is a CSV download.

Source: U.S. Customs and Border Protection; readings from September 13 to October 20, 2026 as saved by gptcbp/border-crossing-data. The numbers are public; any mistakes in presenting them are mine.
