After hearing about the test digs for the canal dock link I went to see if there was any evidence of building work. The holes of the test dig have been filled in now. North of Princes Dock work is being done to prepare for the new lock from the Princes half tide dock to the River Mersey.
This photo (above) shows the earth dams and drainage in preparation for the new lock.
The orange sand in this photo could be from the channel being cut through the infilled dock to the north.
the whole project was at one time proposed to be completed by spring 2007. Doesn't look like it will be. Hopefully work will start before the end of this year.
