SR400 Express Lanes
Fulton and Forsyth Counties, Georgia
LONG provided database surveying services for the design and construction of new Express Lanes on SR 400. The project began on north end of the proposed SR 400 /I-285 Interchange north 15 miles to McFarland Road. Services included setting photo control, setting the horizontal and vertical control network, field surveying obscured areas due to tree cover or bridges, field locating drainage structures, and providing a quality control review of the LIDAR consultant’s work. Up to six field survey crews were employed on this project at one time.
