Cars traveling south on college frequently jump on to the sidewalk at this point. The road turns slightly and the sidewalk narrows right before the train track bridge. I have almost been hit several times and I have see cars drive over the sidewalk almost daily. A child or a runner w/ headphones is going to be killed or seriously injured at some point. The curb should be raised and the sidewalk widened. There should be caution signs and ideally some form of speed suppression right before the bridge.
