It's spring time in Billings and that means construction around the city will start.  Over $100 million worth of projects are in the works.  Planned water, sewer and storm water work will affect North 27th Street as well as Hilltop Road.  South 24th Street West south of Central Avenue will receive a pavement overlay.  Traffic signals will be installed at 54th and Rimrock Road as well as Daniel Street and Monad.  Central between 32nd Street and Shiloh will be widened.  And that's just the tip of the projects.
