Southbound lanes of Jordan Gateway, just north of 11400 South, in front of Walmart. As you approach 11400 S., the right hand lane has a turn lane to enter Walmart. There is a concrete island to direct traffic into Walmart. The Island is not well marked. It needs reflectors added, and paint to make it stand out. It is a little hard to see, and it juts out at a place where drivers who want to turn right on 11400 South are moving over into right turn lane. This exit/entrance from Walmart could be eliminated altogether, but at the least, this island needs better marking. Previous reflectors have been hit and knocked down because it was not adequately marked.
