RALEIGH – Blasting operations are currently scheduled
to begin on U.S. 321 in Blowing Rock Wednesday, June 13, at 10 a.m., weather
permitting. The drilling and blasting
operations will take place in the area near New River Falls Road and
move southward. Affected property owners near any blasting area will be
notified 24 hours prior to blasting. Road closures are
not necessary during this phase of the project. Traffic will be controlled
during this blasting by using flagmen to temporarily stop traffic a safe
distance from the blast area. Lane
closures may be used if needed, and there will be minimal delays.
prepared for the blasting by drilling test areas and performing test blasts last
week. Those test blasts were monitored, and noise and vibration levels were
recorded at well-below project limits. Blasting noise and vibration levels will
depend on proximity to the blast. People will hear an extended “popping” or
low-level thumping sound rather than a loud bang.
This project has
specifications that limit vibration and noise levels associated with the
blasting to well below damage-inducing levels. For more information on blasting
on this project, please go to the project website and click on the blasting PDF, or call the project hotline (828-964-3260)
between 8 a.m. and 5 p.m. You also can check the town’s noise ordinances at www.townofblowingrock.com and
search for “noise ordinance.”
The N.C. Department of Transportation reminds all
motorists to drive slowly using caution in work zones. When lane closures are
in effect, remember to watch for flaggers standing near the roadway and be
prepared to stop.
The speed limit
along U.S. 321 remains 35 miles per hour. The N.C. State Highway Patrol continues
to monitor this corridor for speeding violations.
