I have watched the workers replace the reflector guards on the Thorton south off ramp into Newark, at least 7 times in 2 years. I have yet to see the reflectors stay up more than 4 days! They get run down. Why? can't some off the drivers slow down?? It's crazy and it is little things like this that cost us over and over again! The workers could be fixing other problems if the didn't have keep coming back to this area!
