In order to facilitate the dramatic growth in traffic generated by the proposed McIntosh Village, the GRTA has mandated the following "improvements":
A traffic light at the intersection of Ga. Highway 16 and Broad Street in Senoia.
A southbound left turn ramp at the intersection of Ga. Highway 154 and Interstate 85.
A remake of the Hwy. 74/54 intersection, the major intersection in Peachtree City. GRTA suggests adding a third northbound, southbound and westbound through lanes, along with adding a second northbound and westbound left turn lane and adding an exclusive northbound right turn lane.
A third northbound through lane and a second westbound left turn lane at the intersection of Hwy. 74 and Peachtree Parkway, site of the Kedron Kroger-Target shopping center.
These are in addition to the extension of TDK Boulevard and widening the bridge over Line Creek from two to four lanes.
