The Chicago Harbor Lock, operated by the U.S. Army Corps of Engineers (USACE), is open for vessel traffic as of April 15, marking the end of this phase of construction. The reinforced lock floor was completed last week and included replacing tile from the lock floor using reinforced concrete with micropiles along with dredging excess material. This was done by using dive teams and maintaining a 24/7 construction operation schedule.
