Construction on the Detroit-Windsor Tunnel will take a break for a couple of nights this week and reopen to traffic at night.
The tunnel will be open Wednesday and Thursday, officials with the tunnel said Monday.
The $21.6 million final phase of a project to renovate the tunnel began in November.
Because of the construction, the tunnel that connects Detroit to the city of Windsor, Ontario, Canada, has been closed from 8 p.m. to 5:30 a.m. Sunday through Thursday. The project is scheduled to be finished in June.
Dan Austin, a spokesman for the tunnel, said the construction companies doing the renovation won't be working those two nights and officials decided to open the passage to motorists.
The Detroit-Windsor Tunnel and the Windsor-Detroit Tunnel Corp. are paying for the renovations, which will be completed by Michigan-based Toebe Construction Co.
Detroit-based American Roads operates the tunnel under a lease with the city of Detroit. The company said it has invested more than $50 million in infrastructure, service, safety and security improvements to the tunnel since 1998.
The 86-year-old tunnel is nearly a mile long and 75 feet below the Detroit River. Officials estimated about 12,000 motorists use the tunnel daily.
