Hwy 51, 2 north of Dover, was partly blocked as emergency crews worked a single-vehicle roll-over wreck last Thursday. The wreck occurred at about 1:45pm when a Chevrolet SUV left the roadway and rolled several times coming to rest on its side. No one was badly injured and no additional details were made available. This was the 3rd wreck in the area in over a 1 hour period. The first was just north of Kingfisher and the other was on Dover Crescent Road.
