Atlanta breaks ground on an $18.5 million Monroe Drive road diet, a decade after a teen cyclist's death

Four lanes become three between 8th Street and Piedmont Circle, a project that traces back to Alex Hyneman's 2016 death at 10th and Monroe.

ATLDOT broke ground July 22 on the $18.5 million Monroe Drive Safe Streets project, converting the corridor from 8th Street to Piedmont Circle from four travel lanes to three (one lane each direction plus a center turn lane), with 11-foot lanes to still fit MARTA buses and trucks.

The redesign adds 29 marked crosswalks, two new pedestrian hybrid beacons, six rapid-flashing beacons, bulb-outs, and AI-assisted signal timing, and is projected to cut crashes by roughly 30%. Four lanes stay in place near Ansley Mall at Piedmont Avenue. The project traces to the 2016 death of 14-year-old Alex Hyneman, struck by a driver while cycling near 10th and Monroe; her father Thomas Hyneman co-founded Atlanta Families for Safe Streets and pushed the redesign for a decade.

Construction runs roughly two years, with the full project targeted for completion by 2028. Some neighbors, including the Yorkshire Townhomes HOA, argue the road is already too heavily traveled for a lane reduction; no bike lanes are included due to insufficient road width.

Why it matters

It closes out a decade-long safe-streets campaign born from a fatal crash, and it is a real-world test of how much a road diet costs and how residents react once shovels are actually in the ground.

BeltLine Starts Northwest Trail Segment 3B

Construction has started on Atlanta BeltLine Northwest Trail Segment 3B, a nearly one-mile link from Trabert Avenue to Tanyard Creek Park. The route will bridge Northside Drive, pass through Atlanta Technology Center and under I-75, connecting five northwest Atlanta neighborhoods to the completed Segment 3A and Northside Trail. Atlanta BeltLine lists late fall 2028 as the expected opening.
