Ship ALGOSOO Downbound at Lock 1, Welland Canal (2014)

The downbound ship ALGOSOO is seen on the Welland Canal, approaching Lock 1, Apr. 27, 2014. She is on a typical, routine run, still working hard in her mature years - but in 2016, ALGOSOO would be scrapped in Port Colborne, Ontario. She had been launched in Collingwood in 1974, and was the last front-pilothouse laker to have been built on the Great Lakes.
Note, at the very beginning of the video at the right (and in two of the photos) we see the on-going construction of the new approach wall pier above Lock 1. The existing landing pier which is seen in the video, is built on wooden pier legs, and the canal's water goes right underneath it; originally, the water continued under the pier and went to the canal slope, acting as a 'pond' / swale running along the rear of the pier.
But as is seen here, that pond area has been recently filled in with stone, and is completely gone. We see that a new sheet-steel piling wall has been installed in the water, running parallel to the current pier, and that the former pond area, which had been behind the pier wall, is now gone. Originally, the current pier wall was open on 3 sides to the water underneath.
Installing the new sheet wall and filling in the pond area was the first stage of the pier reconstruction project.
The next stage was carried out the following year, when they demolished the entire old pier wall (the one seen here) and built a completely new pier wall supported on steel I-beam legs. The sheet-steel piling wall seen here, then became the 'back wall' of the new approach pier, and, due to the old pond being gone, now made the new pier open to the water just on 2 sides.
