Zenith Dredge Company, Duluth MN                               

Most recent update: October 24, 2010.

Zenith Dredge was formed in 1905 as a harbor construction company: it only built ships during WWII.  It was located at the foot of 13th Avenue West, where Georgia Pacific is now, and had two ways, launching northeasterly into Slip #7, which was filled in the 1950s: see the site from the air on Google here.  If anyone can add to the table below, please e-mail me at timcolton@aol.com.
