Ambassador Bridge Border Crossing (Detroit–Windsor)

About this crossing

Historical Background

Opened in 1929, the Ambassador Bridge was built to support Detroit’s booming auto industry and Windsor’s manufacturing growth. Named to symbolize U.S.-Canada friendship, it became a trade lifeline for cars and parts. During Prohibition, smugglers used the Detroit River, with a 1930 boat chase becoming local legend. The 1970s saw traffic soar with NAFTA, though trade disputes occasionally snarl operations. Today, it handles millions of vehicles yearly, cementing its role as an economic powerhouse.

Crossing Details and Wait Times

Northbound, you’ll stop at Detroit’s CBP office for an exit stamp, then hit Windsor’s Canadian immigration, needing a passport and possibly a $7 CAD eTA (apply online). Southbound, expect a Canadian exit stamp and U.S. entry rules, typically a passport. Open 24/7, passenger waits are typically under 20 minutes with no delay reported recently, but freight surges (6 to 9 AM, 3 to 6 PM) can hit longer. Summer and holidays spike delays slightly. Check CBSA’s CanBorder app or CBP’s Border Wait Times for live updates.
