Controlled Blasting at South Shaft Runs Smoothly

Contractor Shank/Balfour Beatty is using controlled blasting to excavate into rock at the South Shaft. The blasting began on Tuesday, May 19th and was closely monitored. The blasting is taking place in accordance with OSHA and environmental regulations and all measures are in place to ensure nearby neighborhoods are not impacted by noise or dust. Blasting in the shaft and tunnel will continue until the contractor is ready to launch the tunnel boring machine.

Controlled blasting may take place at the North Shaft location in mid-June if necessary.
