Derry, NH (August 26, 2026) – At least one person was injured on Monday afternoon, August 24, in a collision on the Route 28 Bypass in Derry. It happened around 1:52 p.m., near 63 Bypass Route 28. The Route 28 Bypass is a divided highway that carries traffic around downtown Derry.
Drivers were urged to use caution in the area while crews responded, and it was not immediately clear whether any lanes were blocked.
No further details about the vehicles involved or the cause of the wreck were released. We hope for a full recovery for everyone involved.
Why Are Bypass Roads Riskier When a Crash Happens?
Bypass roads are designed to move traffic around a downtown area at higher speeds than local streets, which can make injuries more severe when a collision does happen. Divided highways like this one typically have fewer intersections than a city grid, but on-ramps and off-ramps still create merge points where speed differences between vehicles can lead to trouble.
Midday traffic on a bypass includes a mix of commuters, delivery vehicles, and drivers passing through town without stopping, which can create inconsistent speeds throughout the day. A driver adjusting to merging traffic or a lane change may have less time to react if another vehicle unexpectedly slows ahead.
When authorities ask drivers to use caution near an active response, it typically means emergency vehicles or personnel are working close to live traffic lanes. Slowing down and being prepared for sudden stops near a response scene helps protect both responders and other drivers passing through.
