McKinley Elementary School, in Arlington’s Madison Manor neighborhood, will open the next school year 131 percent over capacity due to construction delays, school officials told parents this week.
McKinley is in the midst of a $22 million expansion project that was approved in 2014. The expansion will add 241 seats to the school, which opened this school year with a capacity of 443 and an already-burgeoning enrollment just north of 600 students.
