About these numbers

Copied Oct 29, 2026, 9:47 PM Michigan time

Officers at each port of entry post the commercial lanes’ 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. FAST lanes are for carriers enrolled in CBP’s FAST program.

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 averages are a CSV download.
