Tuesday is primary election day in Salt Lake County. Here’s what you need to know.

On Tuesday, Salt Lake County residents in some cities will whittle down the pool of candidates for November’s municipal elections.

The number of people voting in the primary election will be much smaller than past years, because the majority of the county’s municipalities — including Salt Lake City — opted to try a ranked-choice voting pilot. Some cities or townships didn’t have enough candidates file to warrant a primary, including Holladay, South Jordan, Kearns Metro Township, White City Metro Township, Alta and Brighton.

The cities with a primary election this year are Herriman, Murray, Taylorsville, West Jordan and West Valley City. Here’s what voters in those areas need to know.

Can I still mail my ballot?

Monday is the last day ballots must be mailed and postmarked to be counted. For those who missed the deadline, ballots can be deposited at any of the county’s 19 drive-up drop boxes until 8 p.m. Tuesday.

Drop box locations in the cities with primaries include:

• Herriman City Hall — 5355 W. Main St., Herriman.

• Murray City Hall — 5025 S. State St., Murray.

• Taylorsville City Hall — 2600 W. Taylorsville Blvd., Taylorsville.

• West Jordan City Hall — 8000 S. Redwood Road, West Jordan.

• West Valley City Hall — 3600 S. Constitution Blvd., West Valley City.

Voters also can hand off their ballots in person at one of the county’s seven voting centers from 7 a.m. to 8 p.m.

This and more information can be found at the Salt Lake County clerk’s webpage.

I didn’t receive a ballot in the mail. How do I cast my vote?

The last day to register to vote in the primary election was July 30 and the last day to request a replacement ballot was Aug. 3. You can still register and vote in person, with two forms of identification, on primary election day by visiting a polling location.

Voters can check their status by visiting the Utah registration website at https://vote.utah.gov.
