The date for upgrades to Tilly Mill Road has been delayed a week due to expected rain storms this weekend, with work now set to begin Jan. 27 and wrap up Jan. 29.

During construction, a portion of Tilly Mill Road will have to be closed and traffic will be rerouted.

The road closure and detour during this period will begin at the intersection of North Peachtree Road at Tilly Mill Road and extend east to the intersection of Peeler Road at Tilly Mill Road. The road closure and detour will begin at 8 p.m. Friday, Jan. 27, and end Saturday, Jan. 28, at noon. During this period, the detour will re-route traffic north of the road closure utilizing Happy Hollow Road, Dunwoody Club Drive and Tilly Mill Road.

During the afternoon of Jan. 28, the section of Tilly Mill Road will then be open to one lane for additional work all day Saturday and Sunday if needed. The lane closure will be continually monitored and properly flagged and will shift traffic from one side of the road to other to facilitate road work and installation requirements. All work, road and lane closure and detour activities will be dependent on weather conditions during the construction period, according to the press release.

The road closure and detour will permit work crews to replace and install a major portion of storm drain pipe.

“This work is critical to help safely and securely install the new pipe adjacent to and above several major utility lines which serve homeowners and residents at the Assisted Living Facility on Tilly Mill Road,” the press release states.

While the road closure and detour will be a temporary inconvenience, the closure is needed to ensure the proper installation of the storm drain pipe and the safety of the construction crews. The closure also ensures residents in the direct area of the work will have access to homes and driveways. Crews will be on hand to offer assistance.

The affected intersections will be closed off with proper barricades and a police presence will be maintained at both intersections during the road closure and detour period. There will also be detour directional signs onsite and a map rendering of the detour area can be viewed on the Tilly Mill Road at North Peachtree Road Project Page.

  1. Doesn’t the ‘smart’ City of Dunwoody have an individual or entity responsible auditing the progress and quality of this project?

    – How long has this intersection been under-construction?!

    – How many months were sidewalks on both sides of the road simultaneously closed for construction forcing children to walk in the street en route to school or Brook Run?!

    – Why wasn’t lane tape utilized for marking temporary lanes for drivers (especially after the Mt Vernon project incident)?!

    – How many impact flats will my vehicles be subjected to from hitting the the construction incurred potholes (count right now is – two)?!

    1. Let us hope that the company in charge of this project will no longer be allowed to work in Dunwoody. Reminds me of the Johnson Ferry Bridge. issues __”on time”—after several delays…..
