The Laural Avenue bridge has been struck many times. Usually it does not cause disruption to rail service. Years ago there was a significant hill just Southwest of the bridge called by the teens of the time "Thrill Hill". A vehicle at higher speed would leave the ground. The vehicle would come back down to the road just before the bridge. But if it was travelling too fast is would smack into the side of the bridge with tragic results. Hence the hill was removed. Lighter vehicles didn't effect rail but larger trucks could.
