Pelham Mourns Robert Lemieux After September 18 Crash on Interstate 93

 Robert Lemieux, 38, of Pelham, New Hampshire, died Friday, September 18, 2026, after a single-vehicle crash on Interstate 93 in Londonderry. The collision occurred around 1:50 p.m. near mile marker 12, where New Hampshire State Police responded. According to the available account, Lemieux was traveling in a Buick sedan that left the roadway and entered the center median before continuing along the highway. The vehicle eventually struck a concrete bridge support, leaving Lemieux severely injured. Emergency crews responded and transported him for medical care.

First responders arrived and attempted life-saving measures before Lemieux was transported to an area hospital. Despite those efforts, he was pronounced deceased at the hospital. The details establish the crash and medical response, but do not explain why the Buick left the roadway. Authorities had not publicly established whether roadway conditions, mechanical factors, driver actions, or another circumstance played a role. Investigators must determine those questions. The account does not identify the driver or provide details about the vehicle after the collision.

The crash happened along I-93 in Londonderry, a heavily traveled interstate corridor in southern New Hampshire. Investigators generally examine the roadway, vehicle, evidence, and circumstances when determining what occurred. The initial account does not provide details about speed, traffic, weather, or mechanical issues. Without confirmed findings, there is no basis to assign a specific cause beyond the documented roadway departure and subsequent collision. The investigation will determine factors that, if any, contributed to the roadway departure.

For those who knew Lemieux, the official description of the crash represents only a small portion of the story. He was 38 years old and lived in Pelham, but the available account does not provide details about his occupation, family, interests, or other parts of his personal history. Those details should remain separate from confirmed facts. What can be established is that his death followed injuries sustained in the September 18 collision and that his family and friends are now facing his sudden absence.

The crash shows how quickly a routine trip can become an emergency. The Buick left the roadway, traveled into the center median, and continued before striking a concrete bridge support. The impact caused severe injuries that required emergency medical attention and transportation to a hospital. Those facts describe the sequence but do not explain why the vehicle left the roadway. Any further conclusion should wait for findings from the ongoing investigation. The available account does not provide additional details about the medical treatment Lemieux received.

Lemieux's death leaves relatives and friends with grief and unanswered questions. The public record contains few personal details beyond his name, age, hometown, and the crash. Rather than adding unsupported descriptions, the focus can remain on the facts that have been made available. His loved ones will hold their own memories while authorities establish the circumstances surrounding his death. Loved ones must now navigate days ahead without him. No public statements from relatives were included in the available account.

As the investigation continues, additional information may clarify why the Buick left the roadway and whether any other factors contributed to the collision. For now, authorities have confirmed that the crash occurred Friday afternoon near mile marker 12 on I-93 in Londonderry, that the vehicle struck a concrete bridge support, and that Lemieux was transported to a hospital after suffering severe injuries. He was later pronounced deceased. His death has left family, friends, and others who knew him grieving while investigators work to establish the remaining facts.
