DETROIT—An underwater commuter traffic tunnel between Detroit and Windsor, Ont., has shut down for more than a week, the first of a number of closures that will allow construction crews to work on a $22-million renovation project.

The Detroit-Windsor Tunnel closed last Friday night and will reopen Oct. 30 as crews replace the concrete ceiling and make other infrastructure improvements.

Border crossings in the Detroit area will be diverted to the Ambassador Bridge.

Renovations are scheduled to be completed next June and other periodic closings are planned during the construction project.


The tunnel opened in 1930 and runs for nearly a mile beneath the surface of the Detroit River. A more extensive renovation project was completed in the 1990s at a cost of $50 million.

About 12,000 vehicles use the tunnel daily.
