WATERBURY, VT. >> Vermont Gov. Peter Shumlin and other officials are marking the reopening of the state office complex in Waterbury.

More than four years after flooding from Tropical Storm Irene left much of the state office complex in Waterbury unusable, Monday will mark the official reopening of the complex.

A handful of state workers returned to the complex earlier this year.

The $125 million Waterbury construction project was the biggest state construction project in history.

The state employees who were in temporary locations since Irene are scheduled to return to the complex over the next several months.
