Narrative:

On a flight plan at 10;500 feet; I got an oil pressure low alert. Nearest airport was not too far so I turned in that direction. I reduced power and started a slow descent. However the leak was fast and within a few miles pressure dropped to below 10 psi. At this point the engine started running rough so I shut down the engine and turned fuel flow off. I [advised] ATC and said I was going to land. ATC asked if I was going to pull the chute and I asked them to standby as I was looking at a road. I gave ATC my cell phone as they were going to lose radar contact. The road was a 4-lane road and the southbound side had no traffic at all. I saw no visible towers or wires so I lined up with the road. The prop froze at about 1;000 feet.landing was essentially uneventful and after slowing down; I maneuvered the plane into the overrun (about 18 feet of paved overrun). Shutdown the electronics and exited the plane. No part of the plane protruded into the highway. Good samaritan called the local police and between the local police and the highway patrol; they simply decided that some cones along the edge of the highway to alert drivers was all that was needed. I remained with the plane until recovery was complete.
