Gwinnett County school officials last week sold about $305 million in bonds for future school projects.

The bond money will be used to pay for projects approved overwhelmingly by Gwinnett residents in a voter referendum last November. The referendum included a proposal to continue a 1 percent sales tax for new school construction, repairs to existing schools and technology improvements. The referendum passed by a 3 to 1 margin.

Gwinnett expects to receive the proceeds from the bond sale next month, said Bernard Watson, a district spokesman.
