WAYNESBORO, Pa. - Blasting will begin today at Waynesboro Area Senior High School as crews prepare the footings for a 108,000-square-foot addition, school officials said Tuesday.
The detonations - promised to be done outside of school hours - will be accompanied by a public alert system of tones.
Three siren tones will signal the coming detonation, and one longer tone will mark its completion, Superintendent Barry Dallara said.
Blasting of the limestone is expected to continue through at least the end of the school year, Dallara said.
Seismographic equipment will be on site to ensure that safe levels of blast intensity are maintained, according to a school district press release.
Detonations could lead to traffic being stopped on East Second Street for three- to five-minute intervals, according to the release. The block of East Second Street in front of the school will be closed for the duration of the construction project starting sometime in the next few weeks.
