Boston motorists captured the moment over 100 bikers filled a local highway, stopping traffic and wreaking havoc on the roads.

The Massachusetts State Police received a report just after 2 p.m. on Saturday about a group of individuals on bicycles, electric scooters, and dirt bikes in the O’Neill Tunnel, as reported by WCVB.

“First, there were one or two bikes, then around 20 bicycles appeared, and we realized there was a whole procession of them on the road,” Michael Filandro, a driver on the interstate, shared with the news outlet. “At first, I thought it was some sort of parade. There was no escort or police presence. They were disregarding traffic signals and weaving between cars.”

Massachusetts State Police and Boston Mayor Michelle Wu did not immediately respond to Fox News Digital’s requests for comment.

Wu, a Democrat, has come under fire for her handling of crime in the blue city.

“It was unnerving, we didn’t hear it until they were upon us,” recounted Michael Lancaster, who witnessed the unauthorized ride, to WCVB. “They revved their engines to announce themselves. It was a group of riders on motorcycles and dirt bikes speeding through.”
