It's Election Day 2016, Gwinnett, and we know you're excited — but keep one very important thing in mind.

You can't cast your ballot at the county elections office today.

"The biggest issue today so far been people showing up at Elections HQ in Lawrenceville trying to vote," Gwinnett County spokesman Joe Sorenson said in an email Tuesday morning. "This location is only a polling place during early voting. People can deliver their absentee ballots to Elections HQ in Lawrenceville, but all other voting must be done at a voter’s regular polling place."

The county has 156 polling places operating Tuesday, all of which will be open until 7 p.m. Visit the Secretary of State's website to find your polling place.

Sorenson said that, as of about 8:30 a.m., no other major election-related issues had been reported in Gwinnett. One precinct, Ferguson Elementary School in Duluth, opened eight minutes late "due to a problem with equipment," he said.

Another, Sweetwater Middle School in Lawrenceville, opened 12 minutes late "due to a problem unlocking the polling units."

The U.S. Department of Justice announced Monday that Gwinnett will be one of three counties in Georgia where it will deploy federal poll monitors, which are tasked with assuring compliance with federal voting laws.
