Crews have finished the first half of a new Caney Creek culvert on McGinnis Ferry Road and shifted traffic to build the second half.

The milestone comes from the city's Oct. 30 construction update, as reported by the North Atlanta Star. Workers are also raising sections of the roadway with compacted stone to bring it to the correct elevation. That stone layer is the supporting base, not the final paved surface.

The culvert will replace the existing bridge over Caney Creek, carrying water beneath the widened road. The city expects the project to wrap up in 2028.

For drivers, the shift means a changed route through the Caney Creek work zone. The city's Oct. 30 update did not announce a full road closure or detour, and it did not give a date for finishing the second half of the culvert.

Utility work and other construction

Gas lines, storm drainage and overhead utilities are still being relocated along the corridor. Some utility poles have been removed, but that work is not finished. Retaining walls also remain under construction.

In an Oct. 2 Instagram post, the City of Johns Creek said crews had removed H-piles at the culvert near Vicarage Walk to improve sight distance. Utility relocation and culvert construction were ongoing at that time.

Scope of the project

The widening will turn McGinnis Ferry Road from two lanes to four between Douglas Road and Hospital Parkway. Phase 1 covers about 2.5 miles along the eastern portion of the corridor, according to the North Atlanta Star's September report. That report listed a spring 2028 target for completion.

Phase 1 is part of a two-phase widening effort. The city's Instagram post described Phase 1 as running from Ronald Reagan Boulevard, east of the new SR 400 interchange, to Hospital Parkway.

Johns Creek is partnering with Forsyth County and the Georgia Department of Transportation (GDOT) on the work.

When finished, the corridor will include a raised median, new drainage, sidewalks and a north-side multiuse path. Trails are planned to connect to the Big Creek Greenway.

A future western phase, from Douglas Road toward Ronald Reagan Boulevard and Union Hill Road, is separate from the current construction and will require additional funding, the North Atlanta Star reported in September. The city's project page lists 2028 as the expected completion date for the active phase.
