What the feed says about operation

Seasonal and temporary changes
Hours change for construction, staffing and weather, and the agencies do not publish a seasonal schedule in the feeds we use. We show the hours exactly as each source states them, with the date we read them. If the live panel on the wait page shows the crossing closed, believe it over any posted hours.
