HOPKINTON, Mass. — A construction site incident in downtown Hopkinton disrupted traffic Wednesday afternoon when debris from a partially collapsed structure spilled into Main Street, prompting road closures and warnings from police.

The Hopkinton Police Department issued an alert urging drivers to avoid the area until the site could be stabilized and cleared. “Drivers are urged to find alternative routes until the area can be cleared,” police said in a statement.

Images from the scene show construction debris leaning against a fence and spilling into the roadway, suggesting that part of a building under development gave way. The collapse created safety hazards not only for motorists but also for pedestrians navigating the busy corridor.

Authorities quickly blocked off the section of Main Street near the collapse. Crews were dispatched to assess the extent of the damage and determine next steps for removal. Police did not immediately confirm whether any injuries occurred, though early indications suggested the site was evacuated safely.

The incident comes amid ongoing redevelopment efforts along Hopkinton’s Main Street corridor, a project that has included significant construction and infrastructure upgrades over the past year. While construction-related disruptions are common in growing communities, the collapse highlights the risks associated with active building sites in heavily traveled areas.

NBC10 Boston reported that a crew was on the way to the scene to gather more details, which are expected to be released once officials complete their initial safety inspections. For now, the focus remains on clearing debris and ensuring the stability of the surrounding site before reopening the road.

The event has sparked concern among residents who rely on Main Street for daily commutes. With Hopkinton serving as a key connection point for commuters heading toward I-495 and the Boston Marathon route, even a partial closure can create ripple effects for regional traffic.

As of Wednesday evening, police continued to monitor the situation and warned that traffic delays would likely persist into the late afternoon and evening commute.
