The Detroit-Windsor Tunnel will close nightly for construction over the next month as part of its $21.6 million renovation.

From June 23 to July 19, the tunnel will be closed from 9 p.m. to 5 a.m. almost every day, Detroit-Windsor Tunnel president Neal Belitsky said in a statement.

Exceptions include June 24, when the tunnel will stay open for the International Fireworks display, and July 4-6, when the tunnel will remain open for Independence Day travelers. Any closures after July 19 will be publicized ahead of that time.

The tunnel renovations began in January 2017 and have periodically closed the tunnel for electrical work, ceiling replacement, and masonry, among other maintenance. The 88-year-old tunnel, which runs under the Detroit River, serves more than 4 million vehicles each year.
