There is an almost constant stream of trucks traveling up and down Willow St. They are dangerous because there isn't enough room for them on this narrow street. There are signs posted saying "No Thru Trucks" but nobody pays attention to them. The police in New Haven are cracking down on all of the bike riders in the city, but giant speeding trucks traveling on narrow streets that can barely fit cars are just fine! They endanger pedestrians, cars, bikers, and they rip down branches from the trees as they speed along.
