Area transportation policymakers have put the brakes on a new Cleveland Highway/U.S. 129 bridge over the Chattahoochee River until issues can be worked out about the proposed route. The new bridge “would have a whole lot less impact on citizens if it (was built) on the left-hand side” of the current structure, also known as Longstreet Bridge, instead of right of the bridge heading north as now proposed, Gainesville Mayor Danny Dunagan said. “And it would be cheaper because it won’t impact anyone,” he said, speaking at the Gainesville-Hall Metropolitan Planning Organization’s Policy Committee meeting Tuesday at Oakwood City Hall.
