Project Update -1

The Pinkham fish passage restoration project is underway. The contractor mobilized to the site last week and began demolishing the concreted channel and existing bridge. This week all of the demolished materials were removed from the site. The contractor then began to excavate on either side of the creek at the location where the new bridge abutments will be constructed. Screened and properly compacted soil has been added to the base of the excavated area and forming of the new abutments should begin next week.

Earlier in the week Shaw contracting worked to remove the last of the concrete from the stream. Large rocks that were grouted into the stream banks and found in the channel will be reused in the new stream channel and rock slope protection later on in the project. 
 The large excavation marks the location of the northern new abutment. The contractor worked on both sides of the creek this week to excavate out what will be the base of the newly built abutment. 
From the north bank back across the creek at the south bank shows the large excavations for each abutment. Additionally the large amount of rock that was pulled out of the existing stream channel and banks that will be reused as rock slope protection and the new stream channel.
