North Campau Neighborhood: Truck Traffic & Air Quality Findings (Aug 13–27, 2025)

The Trucks Off Our Streets (TOOS) Dashboard study in the North Campau Neighborhood (District 3) investigated local truck traffic and air quality near the Stellantis Mack Assembly Plant and major thoroughfares.

Truck Traffic Findings (Newbern & Victoria St.)

The study monitored a specific residential intersection that was a concern for residents.

Note: While traffic was low at the camera's location, community concerns about industrial trucks using Gallagher Street as a cut-through persist.

Air Quality Findings (PM2.5)

Despite the low truck count at the camera site, air quality readings revealed a pattern of frequent, dangerous pollution spikes.

  • Overall Average PM2.5: Good at 8 μg/m³ (below the EPA safe limit of 9μg/m³ 

  • Good Air Days: Air quality was considered "good" over 80% of the time.

  • The Danger: Pollution Spikes Occur Nearly Every Day.

    • Peak Time: Most spikes occurred between 12 PM and 6 PM.

    • Highest Spike: One reading hit 47.48 μg/m³ (August 16), classified as Unhealthy for Sensitive Groups.

Health Risk Reminder

Frequent high-level spikes of PM2.5 pollution—even if the overall average is low—are linked to asthma, heart disease, and respiratory illness. Nearby heavy-traffic roads and industrial facilities mean the community is vulnerable to these sudden, high-risk pollution events.

Protect Your Health & Advocate for Change

Even with a low average, action is needed to manage frequent pollution spikes from nearby industrial and traffic sources.

1. Protect Yourself

  • Check Daily Air Quality: Subscribe to alerts at justair.app/signup

  • Indoor Protection: Use Air Purifiers in bedrooms/living areas.

  • Limit Exposure: Check the air before extended outdoor activity, especially between 12 PM and 6 PM.

2. Advocate for Structural Change

  • Green Buffers: Advocate for trees and vegetation along busy roads to filter pollution.

  • Investigate Spikes: Demand environmental agencies investigate the cause of the pollution spikes and the cumulative impact of all local industrial and truck traffic.

  • Traffic Solutions: Push for policies that reroute heavy trucks away from residential streets and schools, and limit traffic during peak pollution times (12 PM – 6 PM).
