GDOT Sets Oct. 8 as Tentative Start Date for Major 24/7 Lane Closures on I-285

[vc_row][vc_column][vc_column_text]The Transform 285/400 transportation project will soon enter its most transformative stage. Beginning as early as Saturday, Oct. 8, 2022, the Georgia Department of Transportation (GDOT) has announced that its construction contractor will close two left-hand lanes in each direction of I-285, between Roswell Road and Ashford Dunwoody Road, for bridge demolition and reconstruction of a 50-year-old bridge at Glenridge Drive, State Route (SR) 400, and Peachtree Dunwoody Road. The closure of one lane in the westbound direction will follow approximately two weeks later. A visual of the planned closure area can be seen above.

Lane closure schedule confirmation will come after certain I-285 construction milestones open to traffic, ensuring motorists know what to expect and when. These anticipated openings will provide some additional capacity for vehicles and maximize all new connecting lane availability outside of existing lanes.

Key milestones include:

  1. I-285 westbound connecting lane from Peachtree Dunwoody Road to past Roswell Road
  2. SR 400 northbound and SR 400 southbound to I-285 eastbound connecting lane to past Ashford Dunwoody Road

The lane closures are expected once these key milestones are open to traffic and updated signage is in place.

  • Phase 1: Inside lanes will close on I-285 in each direction between Roswell Road to Ashford Dunwoody Road, so crews can reconstruct the interior portions of the I-285 bridges over Glenridge Drive, SR 400, and Peachtree Dunwoody Road. A minimum of three lanes will be open in each direction. This phase will take approximately four months.
  • Phase 2: Traffic will shift to the inside lanes providing width for three travel lanes and the existing outside lanes will close to traffic so crews can demolish and reconstruct the exterior portions of the bridges. This phase will take approximately four months.

The I-285 lane closures were originally scheduled to be implemented in September 2021. The reason for delaying the lane closures was to complete more work in the interchange as well as build out connecting lanes.

Parallel collector-distributor lanes being built as part of the Transform project should help to absorb some of this disruption and smooth merging in the area. Once completed, the 285/400 interchange will be able to handle more vehicles with less delay, providing a better experience for those coming to Perimeter or passing through on I-285 or GA-400.[/vc_column_text][vc_single_image image=”9018″ img_size=”full” alignment=”center” onclick=”custom_link” link=””][vc_column_text]These bridge replacements and associated I-285 lane closures will take an anticipated eight months to complete and profound delays can be expected during this time, potentially adding an hour or more to daily commutes.

Perimeter Connects—the Perimeter Community Improvement Districts’ transportation program—has put together key travel planning resources to help commuters traveling to and around the Perimeter district navigate traffic impacts from this major closure. This includes commute planning and communications tools for employers who may have teams traveling into the office throughout the week.[/vc_column_text][vc_btn title=”See More” style=”classic” color=”info” align=”center” i_icon_fontawesome=”fas fa-hard-hat” add_icon=”true” link=”|title:Lane%20Reduction%20Resources”][vc_column_text]
