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

The incident was initially reported just after 2 p.m. on Saturday, after Massachusetts State Police received a call regarding a group of people on bicycles, electric scooters and dirt bikes in the O’Neill Tunnel, according to WCVB. 

“Here comes [one to two] bikes, then 20 bicycles and we realize there is a whole wagon train of them down the road,” Michael Filandro, who was driving on the interstate, told the outlet. “I thought it was a little parade or something going on. There was no escort, no police there. They were blowing through traffic lights, zipping around 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 scary, we didn’t even hear it coming,” Michael Lancaster, a witness to the unlawful ride, told WCVB. “They just revved their horns to make themselves known. Just a bunch of dudes on motorcycles. They just came ripping through on dirt bikes.”
