Back in the 1970's I worked for a trenching contractor digging trenches for joint utility services to.privare and commercial buildings. Often the job would require crossing long established streets and roads, sometimes major thoroughfares and multi lane avenues. In such situations the utility company (Pacific Gas and Electric) had to try to auger under the street and only if that failed, and it often did, could they dig a trench across the street which was usually very time consuming and expensive. Besides the usual asphalt and/or cement surface layer there was often around a foot to18 inches of compacted base rock.....sometimes concrete treated, that took great effort for the backhoe and often a 90 lb. jackhammer to dig out. A lot of work was put into these augering jobs and often the backhoe positioned to do the pulling on the angering equipment which was usually powered by a compressed air motor/gearbox unit driven by a compressor unit on one of the utility company trucks. Real challenging job sometimes, believe me..........
