Gainesville is about to embark on a $1.5 million project to not only improve aging sewer in an area near the historic Gainesville Mill, but put the area in better position for growth. Rainy weather has held up work this week, but crews could soon begin on the project along Marler Street between Hancock Avenue and Dean Street. That section of road will be closed to motorists until Nov. 13 as work gets underway, city officials said.
