Key West Engineering Service Project Manager Barry Barroso, left, discusses directional boring with the crew of Horsepower Electric while they work on the 500-600 block of Front Street. The crew, Raul Burges, supervisor; Aurra Villa and Jorge Silva have used the directional boring machine to dig under sidewalks for the placement of old fashioned street light poles on Upper Duval Street, Petronia and Front streets. Barroso said the machine allows the placing of the light poles without having to dig up sidewalks or streets.
