While en route, the plt contacted a fss & was advised that the Redding arpt was below minimums due to fog. He then contacted the benton UNICOM (7 mi nw of Redding muni) & reported that he could not see the rwy lights at the benton arpt, but that he would attempt to locate enterprise arpt which was 5 mi east of benton. Also, he stated that he was low on fuel, & since he could see the lights on eureka way (California state highway 299W), he would use it if necessary. A short time later, the acft collided with 2 overhead ground lines which were associated with the shasta tracy 230 kv transmission line. The cables were 1/2 inch in diameter & located near eureka way, 120 ft AGL, & aprx 1-1/2 mi from the benton arpt. After hitting the cables the acft impacted on eureka way. An exam of the wreckage revealed no evidence of a preimpact/mechanical problem.
