I-285/SR 400 Interchange Reconstruction P.I. # 0000784

SR 400 Collector-Distributor (CD) Lanes P.I. # 721850

Combined Project Info

Dear Ms. Clowers & Mr. Lobdell:

For the above mentioned projects, we strongly recommend and encourage the Georgia Department of Transportation to:

1. Build a Multi-Use Path along the project boundaries for dedicated separated bicycle/pedestrian facilities Greenway along both GA-400 & I-285. The GA-400 trail would eventually link to the south to the PATH400 trail in Buckhead running along the GA-400 ROW (planned to connect to the Atlanta Beltline), and north into the Roswell & Alpharetta trail network. Along I-285, the trails will provide connectivity from the heart of Perimeter CID into their work-in-progress “Commuter Trail Plan” network where over 100,000 employees work each day; eastward to Dunwoody, Chamblee and the redevelopment-in-progress former GM plant in Doraville; south to Medical Center MARTA and Brookhaven; and west to the new Sandy Springs City Center and commuters from East Cobb. As a minimum, with formal coordination with the PATH Foundation, leave accommodation within each project space for a future Multi-Use Trail to be built; designating in project design documents the physical space allocated for the trail.
2. Follow urban-setting best practices and context-sensitive bicycle facilities for on-street segments of the project areas, including all bridges. Insure facilities follow the GDOT Complete Street Design Policy & Manual and allow the use of the NACTO Urban Bikeway Design Guide (adopted by the City of Atlanta & supported by the FHWA ) for these facilities and minimize or eliminate the use of “Sidepaths”, and instead use “Cycle Tracks” aka “Protected Bicycle Lanes”. Refer to the “Green Lane Project” for use within the US.
3. With the Diverging Diamond Interchange at Abernathy & SR-400, build continuous bicycle and pedestrian pathways separated from vehicular traffic with grade separated undercrossings at the freeway ramps. This will be a dedicated, separated Multi-Use Path that is outside the motor vehicle travel space. One will be running north & south along SR-400. The other will run east & west on Abernathy. Refer to the US-36 interchange in Sacramento, California that was opened in 2014 for an example.
4. Design sidewalks on both sides of streets along all segments
5. Hold planning review meetings with appropriate GDOT Staff, Engineers and Stakeholders including Georgia Bikes, ARC Bike/Ped Planners and the PATH Foundation; to ensure these items are incorporated into each project’s design and approved by GDOT Senior officials, as well as the respective jurisdictions.

Providing these safe accommodations will lead to increased commerce and jobs, reduce on-street motor vehicle congestion, increase adjacent residential property values, improve public health and attract & retain employee talent — especially Millennials who insist on these amenities — which will comprise 75% of the workforce by 2025.

In Georgia, 81% of respondents to a GOHS / UGA survey either strongly agreed or agreed that they would ride a bicycle more frequently if their community had better bicycle facilities such as bike lanes or multi-use paths.

The adjoining cities of Sandy Springs, Brookhaven and Dunwoody have a combined population of nearly 200,000 people. Nearly fifty percent of all trips in metropolitan areas in the United States are three miles or less and 28 percent are one mile or less – distances easily covered by foot or bicycle. SR-400 & I-285 are considered as barriers to many persons who may wish to choose a non-motorized transportation option to go to work in the Perimeter area each day. With even a single-digit percentage mode shift away from motor vehicle commuters to bicycle or pedestrian transportation, congestion mitigation can be attained.

These projects are in great part being built to accommodate future growth in a Transit Oriented Design region. Accordingly, the GDOT Complete Streets policy mandates accommodation of multi-use paths, sidewalks and bike lanes throughout. Applying safe Multi-Modal options for pedestrians and bicyclists last mile connectivity of “Safe Routes to Transit” with access to the three MARTA rail transit stations and get to their offices can ease on-street motor vehicle congestion. To build the project in the heart of a TOD without fully accommodating the alternative modes will greatly shortchange the project achieving its goals. In contrast, incorporating these alternative modes as we suggest will both achieve the project goals and serve as a national model.

Sincerely,

FHWA Diverging Diamond Interchange Informational Guide, August, 2014. Chapter 3, Multimodal Considerations. Clearly identifies 3 basic options for accommodating bicycles at a DDI.

Sidepaths have inherent difficulties in built-up urban areas. Need to consider transition areas at the project boundaries. What facilities are existing & planned to connect to the project area? One-way or two-way?

Consider Cycle Tracks / Protected Bike Lanes per the “Green Lane Project” guidelines. See example on 10^th Street in Midtown Atlanta.

Austin, Texas: Building a bike/ped path as part of the MOPAC highway project. They justified using federal CMAQ funds for it by showing that the completion of the missing link in the bikeway system would reduce congestion on the highway, allowing them to delay or eliminate the need for an additional lane on the highway, which would be way more expensive.

US-50 Interchange, Sacramento, California

Constructed a continuous bicycle and pedestrian pathway separated from vehicular traffic with grade separated undercrossings at the freeway ramps.

Think of having something like this for the Abernathy / SR-400 Interchange, on the underpass of SR-400. It is proposed that interchange become a “Diverging Diamond”, similar to what is on the Ashford-Dunwoody bridge over I-285.

Why do we want a separated & dedicated path at Abernathy?

A consultant working for GDOT told us that with the current design of the Diverging Diamond, persons on bicycles would dismount & “act as a pedestrian”, sharing the sidewalk to go through the Diverging Diamond…. Hmmmm.

Please take a few minutes to review this video of Charles Marohn of Strong Towns narrating a “response” to an engineer’s tour of the pedestrian & bicycle features of a Diverging Diamond Interchange. The current GDOT design for persons on foot or on bicycle is nearly the same as in this video. After watching this, do you think you’d be comfortable?

Do you think GDOT can do better than this to provide a safe & comfortable experience for people on foot or by bicycle? We think so.

FHWA Guidance: Under the United States Department of Transportation Policy Statement on Bicycle and Pedestrian accommodation:

“The DOT policy is to incorporate safe and convenient walking and bicycling facilities into transportation projects. Every transportation agency, including DOT, has the responsibility to improve conditions and opportunities for walking and bicycling and to integrate walking and bicycling into their transportation systems. Because of the numerous individual and community benefits that walking and bicycling provide – including health, safety, environmental, transportation, and quality of life – transportation agencies are encouraged to go beyond minimum standards to provide safe and convenient facilities for these modes.” 

Can’t Afford Not to: Dedicated Bicycle & Trail Accommodations add value to local businesses & homes. Improve Health, Increase local transportation options. All adds up to an excellent long-term Return on Investment.

Safe Routes to Transit: Allow Non-Motorized access from MARTA stations to employment centers, providing a SAFE transportation option, relieving local motor vehicle rush-hour traffic.

Plan for the Future: Bridges last 50+ years. Millennials are looking for walkable, bikeable communities & will relocate their businesses & create new jobs where this infrastructure exists. This trend will increase.

Regional Connected Network:  PATH400 Trail is being built northward along GA-400 up to the Sandy Springs city limits. Roswell trail system connects into Alpharetta with plans to connect into the Forsyth County trail network. is the single point of access between Perimeter CID, Dunwoody, Sandy Springs to cross the Chattahoochee River into Roswell, connecting into their trail & bike network and points beyond.

Supports Existing Plans: Perimeter CIDs Commuter Trail Plan, DeKalb County 2000 Trail Plan, Sandy Springs 2014 Bike/Ped Trail Plan, Dunwoody Comprehensive Land Use Plan and City of Brookhaven plans reference connection to regional trail networks. Chamblee & Dunwoody planning to conduct an LCI Study of the 285 corridor, including Multi-Modal transportation. Connectivity to Doraville former GM Plant for Live-Work-Play.

Revive 285 designates Multi-Modal transportation options along these corridors.
