The preferred alternative includes two 10 foot travel lanes separated by a 13 foot shared turn lane along the entire corridor. There is an additional travel lane in each direction along the southern section of the corridor between Cotillion Drive and Old Spring House Lane. A 12 foot multi‑use trail runs along the west side of the entire corridor, while a 10 foot sidewalk runs along the east side of the corridor between Cotillion Drive and Old Spring House Lane, changing into a 12 foot multi‑use trail north of Old Spring House Lane. Multi‑use trails run along both sides of Chamblee Dunwoody Road from Old Spring House Lane, connecting to the existing multiuse trail at Georgetown Park, and continuing to the northern terminus of the project. Both the sidewalk and the multi‑use trail are separated from the roadway by a 6 foot planted and hardscaped buffer area. Right of way limitations may necessitate altering the width of landscape or hardscape area on the west side of Chamblee Dunwoody Road, north of Old Spring House Lane.
There are multiple median refuge islands proposed for mid‑block pedestrian crossings along the northern part of the corridor between Old Spring House Lane and the roundabout at Peeler Road/Chamblee Dunwoody Road/North Shallowford Road, including one at the entrance to Georgetown Park. A planted median runs between the two directions of traffic along the south end of the corridor north of the intersection with Cotillion Drive. Auxiliary lanes are provided throughout the corridor as required. This alternative modifies the existing conditions by creating more consistent lane allocations on Chamblee Dunwoody Road south of Old Spring House Lane (maintaining a 5‑lane cross‑section), adding a second through lane on Chamblee Dunwoody Road southbound at the intersection of Cotillion Drive/I‑285 Westbound On‑Ramp, adding a shared center turn lane to Chamblee Dunwoody Road north of Old Spring House Lane, adding pedestrian refuge islands at various locations north of Old Spring House Lane, and adding continuous sidewalks and/or multi‑use trails along both sides of the corridor. This alternative was found to be most favorable by the public and Dunwoody City Council. The total length of the project corridor is .65 miles.
