   It looked like a rocket had exploded in the street last Thusday--mountains of earth heaped near a bus-sized crater, dust everywhere--but it was only the final stages of a sewer extension project that's suffered from a severe bout of Murphy's Law.
  
   The street, 132nd Ave. N.E. near the Woodinville city limits with Bothell, was closed two weeks longer than anticipated while crews used a number of techniques to bore an eight-inch 660-foot-long sewer line deep under the road.
  
   What started out three months ago as a "horizontal directional bore" on the side of the road turned into a series of open pits. The first bore ran into a large rock. "Bellys," unacceptable to the city of Bothell, were discovered in one, while another went off line.
  
   For the 10-unit single family development known as Wynwood Green, the Firloch Corporation was required to hook to an existing sewer line buried more than 20 feet deep.
  
   Soil structure also provided trouble. Dean McKee, Woodinville Permit Services Director, said there had been hope that one lane of the road could've remained open to traffic, but the sandy walls of one pit, about 11-feet wide by 60-feet long by 24-feet deep, were a constant threat to cave in. Workers in the bottom of the pit installing the sewer line by hand were protected by a two-sided steel structure placed over the line.
  
   Klinker said 132nd would be paved Aug. 10.
