To All:


Again, weather issues have postponed the dates for the center span float out/in of the Merchants Railroad Bridge. A 10-hour blockage of the main navigation channel is now scheduled to start at 6 a.m., February 26, 2022, for this evolution with up to a 24-hour closure of the middle span.


To float-in the new center span, another 12-hour blockage of the main navigation span will be required starting at 6 a.m., February 28, 2022, with up to a 24-hour closure of the middle span.  These dates are dependent upon weather and river conditions encountered between now and the dates noted.
