Car Insurance in Andover: A High-Income Growth Suburb

$137,593. That's the 2024 median household income in Andover, one of the highest figures of any suburb in Anoka County, and it's a big part of why car insurance here runs an estimated $1,152 a year for full coverage — well under Minnesota's $2,414 statewide average.

But the same city that can afford that income has also grown faster than almost anywhere else in the north metro. Andover's population has climbed from 9,387 residents in 1980 to roughly 36,360 today, nearly quadrupling in less than half a century, and the road network is only now catching up to what that growth demands.

What Insurance Actually Costs in Andover

Aggregator data pegs full coverage in Andover at around $96 a month, or about $1,152 a year, for a clean-record driver. That's a meaningful discount against the statewide full-coverage average of $2,414, and it tracks closely with Andover's income profile — insurers use household income and credit-based factors as a proxy for claims risk, and Andover scores well on both.

No carrier publishes an Andover-specific rate table, so treat this as directional rather than guaranteed. Your real quote depends on your ZIP code — mostly 55304, with a small piece of 55303 — plus your vehicle, driving record, and coverage limits.

From Grow Township to a $137K-Income Suburb

Andover wasn't always Andover. The area was first organized in 1857 as Round Lake Township, renamed Grow Township in 1860 after Pennsylvania congressman Galusha A. Grow, and didn't incorporate as a city until 1974. The name "Andover" first shows up in an 1899 newspaper article — before any train tracks reached the area, which quietly debunks the local myth that the city was named after a rail stop.

What changed everything was the decades that followed. A township of 330 residents in 1860 is now a city of roughly 36,360, with median household income more than double what neighboring Coon Rapids ($87,335) or Blaine report. That kind of income growth is a large part of why Andover prices below the state average despite its population boom.

Why the Roads Are Still Catching Up

County Roads 9, 18, 78, and 116 carry most of Andover's local traffic, with Bunker Lake Boulevard (County Road 116) as the main east-west spine connecting to Highway 65. That intersection has run on traffic signals for years, built for a much smaller commuter base than the one driving through it today.

Anoka County and MnDOT are now converting it into a grade-separated interchange, carrying Highway 65 over Bunker Lake Boulevard on a new bridge with a roundabout underneath in place of the signals. The project landed $7 million through a congressional direct-spending program in late 2025 and another $4.3 million in Minnesota's 2026 state bonding bill.

A Second Roundabout Down the Road

Bunker Lake Boulevard is also getting a separate roundabout where it meets Naples Street NE, near Andover's border with Ham Lake. That project cleared its archaeological survey and was tracking toward 60% design plans by mid-2026, part of the same push to replace aging signalized intersections with roundabouts across the corridor.

Construction zones and new traffic patterns tend to nudge claims frequency up in the short term — more merging, more drivers unfamiliar with a just-opened interchange — even in a city where the long-term rate trend points down.

Minnesota's No-Fault Rules Still Apply

Every Andover driver carries the same statewide floor: 30/60/10 liability — $30,000 bodily injury per person, $60,000 per accident, $10,000 property damage — plus $40,000 in Personal Injury Protection, split $20,000 medical and $20,000 non-medical. Minnesota's no-fault system means your own PIP pays your medical bills first after a crash on Bunker Lake Boulevard or anywhere else in the city, regardless of who caused it.

• Confirm your garaging ZIP code: 55304 covers most of Andover, with a small slice in 55303.
• Expect short-term construction risk: the Hwy 65/Bunker Lake Blvd interchange and the Naples Street roundabout will bring new traffic patterns through at least 2027.
• Raise UM/UIM above the 25/50 floor if you can: roughly 1 in 9 Minnesota drivers carries no insurance at all.

Andover's income numbers explain why the average policy here undercuts the state average. Its population chart explains why two intersections are getting rebuilt at once. Both trends point the same direction — just not always on the same timeline.
