Nearly a third of Anchorage’s registered voters have cast ballots in the city’s first vote-by-mail election as of Tuesday afternoon, with about six hours to go before in-person polls close.

About 63,000 ballots have been received by Municipal Clerk Barbara Jones’ office, election officials tweeted at 1:20 p.m. Election Day. That total represents roughly 28 percent of Anchorage’s roughly 218,000 registered voters, as well as roughly 5,500 votes more than received in 2015 -- the last municipal election featuring a mayoral race, which was conducted at traditional polling places.

About 50,000 ballots had been returned by Monday, but more than 100,000 ballots had yet to be returned.

Voters can return ballots mailed by the city to a number of physical dropoff boxes by 8 p.m. Tuesday, as well as accessible voting centers. Ballots can also be mailed if they’re postmarked Tuesday, with the post office near Ted Stevens Anchorage International Airport the city’s latest-closing Tuesday at 11 p.m.
