UPDATED 8AM: Blasting on Highway 20 near Smartsville continues today, but has been delayed until later this afternoon. CalTrans says in order to make up for weather delays, two operations have been consolidated into one, in an area that covers about two football fields. The blasting should start around 4pm, and motorists can expect up to an hour delay. Hammonton-Smartsville Road is the alternate route. Today’s operation will mean that no other blasting will need to be done this week.
