WINDSOR -- The Windsor-Detroit tunnel will be shutting down overnight for four days over the next several weeks due to ongoing renovations.
Tunnel officials say the border crossing will be closed from 9 p.m. to 5 a.m. on Oct. 17, 24 and 31 and Nov. 7.
They say additional temporary closures will be needed to complete the renovations that began in 2017.
The US $22-million project includes replacing the 89-year-old tunnel's concrete ceiling.
The work, which includes masonry, electrical work and other infrastructure improvements, began in October 2017 and was originally to be completed by mid-June 2018.
The tunnel opened in 1930 and runs beneath the surface of the Detroit River.
About 12,000 vehicles use the tunnel daily.
