$3M in campus repairs and improvements will result in a replaced track and new turf at Danbury’s Immaculate High School Mustang Valley athletic field and track complex. Upgrades will also be done to the building and parking lot. A groundbreaking ceremony is set for 12:30pm on June 6 on the field which serves students from 28 communities in Connecticut and New York. It all comes about as part of a $4 million capital campaign marking the 60th anniversary of the private Catholic high school.
