Heading east when the single lane construction zone was established before the fatal accident occurred, I was surprised that there was no signage/markings to show the end of the single-lane stretch. I'm familiar with the road and frequent construction controls, but I had to stop and think to make sure the one way stretch had indeed ended. We all are responsible for safe driving, but I could see that this could be especially confusing to someone unfamiliar with the road used to driving on the left. Not to make excuses, but its possible that clear signage confirming that drivers should move back into the right lane, could have tipped the balance here.
