Costs have more than doubled for right-of-way acquisition in the planned widening of Ga. 347/Lanier Islands Parkway in South Hall County. Originally estimated to be $5 million, right-of-way acquisition for the project, which runs between McEver Road and Lake Lanier Islands resort, is now at $10.25 million. “About every way possible, the right-of-way prices went up,” said Teri Pope, district spokeswoman for the Georgia Department of Transportation.
