Baltimore Harbor Tunnel 50th Anniversary

The Baltimore Harbor Tunnel turns 50 November 29, 2007....
50 Years of Keeping Maryland Connected!

On Nov. 29, 1957, then Governor Theodore R. McKeldin and the Members of the State Roads Commission celebrated the dedication of the Baltimore Harbor Tunnel, an engineering marvel that broke the "Baltimore Bottleneck" and reduced the hour-long crawl through city streets to just 15 minutes. The tunnel provided long-needed relief for travelers in Baltimore and in the region.

Today, nearly 72,000 vehicles use the Baltimore Harbor Tunnel each day, more than double the original estimated volume of daily traffic. More than 60% of drivers at the tunnel pay their tolls with E-ZPass, helping to keep the "Baltimore Bottleneck" a thing of the past.
