BANGOR, Maine — The allure of $4 lobsters was cited as the cause of a traffic backup early Friday evening.

Bangor police Lt. Tom Reagan said the lobsters were being sold from the parking lot of a commercial building near the intersection of Broadway and Cumberland Street and that so many people wanted in on the deal that traffic was backed up almost as far as Interstate 95.

Reagan said police were alerted to the backup by a resident of 81 Broadway, who called police after she found herself unable to get into her driveway because of the congestion.

He also said it was not clear to police how news of the sale spread, speculating that it likely was by word of mouth.

The vendor’s name was not available Friday evening, Reagan said. He said no one was charged in connection with the incident.
