Construction is well underway on a Safe Routes to Schools project improving pedestrian and bicycling access to several Gainesville city schools. Sidewalks are being built on Ga. 11/Park Hill Drive between Roper Hill Road and South Enota Drive, which leads to Enota Multiple Intelligences Academy at 1340 Enota Ave. The $564,432 project also calls for similar work intended to benefit Centennial Arts Academy, New Holland Core Knowledge Academy, Fair Street School and Gainesville Middle School. Construction is about 30 percent complete and the completion date is Dec. 31, said Teri Pope, district spokeswoman for the Georgia Department of Transportation.
