The city is coordinating with various government agencies to ensure the implosion at 1170 Eighth Ave. goes smoothly. Roads will be closed and air quality monitored. Robert Novatnack, the city’s emergency management director, has said the city will share a map with the public showing the hot zone (where the demolition is taking place), a warm zone (where emergency personnel and demolition contractors will be) and a cold zone (where the public can safely watch the demolition). The map will show which roads are closed and which areas are restricted around what has been a Lehigh Valley landmark for nearly 47 years.
