Lexington has officially broken ground on the new high school building.

The $660 million project — the largest in the town’s history — is slated to open in time for the 2029-2030 school year.

“A society grows great when old men plant trees whose shade they know they shall never sit in,” School Building Committee chair Kathleen Lenihan said at Tuesday’s groundbreaking ceremony, quoting an old adage.

State Treasurer Deborah Goldberg, representatives from the Massachusetts School Building Authority, the town’s state legislative delegation, members of the select board, school committee, and others grabbed shovels and ceremoniously dug in.
