BOYNTON BEACH, Fla. (CBS12) – All lanes on Boynton Beach Boulevard and Lawrence Road have reopened after a water break caused a massive sinkhole last week. “Kudos to everyone who has worked quickly, diligently and tirelessly since 2 a.m., Wednesday when a semi-truck became stuck in the sinkhole after a main break caused the asphalt to become unstable,” the City of Boynton Beach said in a Facebook post.
