Salt Lake City street crews, including supervisors and managers, were out in force this weekend, trying to get a head start on filling pot holes and making other street repairs. Burke Dalton, south district manager, said crews focused on major traffic arteries under city jurisdiction such as South Temple, 21st South, Ninth East and others. While city crews had made temporary repairs earlier this year, recent warm weather made it possible to move in and attempt permanent repairs, Dalton said. Crews worked until dark Friday and then put in 12 hours on Saturday. Another 12-hour day was planned for Sunday, but that effort was shortened when the plant supplying the hot asphalt broke down. "We sent out some fliers asking the people to bear with us," Dalton said. "We'll keep right at it and hope we can make most people just a little bit happier."
