The section below covers key issues related to to the transportation infrastructure in Area 11, including maintenance, congestion, and the road network.

Funding Prioritization

The Regional Transportation Plan is responsible for prioritizing all federally-funded transportation infrastructure projects. ​​

Road widening (adding new lanes) or road extensions (new streets) projects are expensive and often compete for limited federal and state funding.  

One lane mile (a single lane of traffic) costs about $351,000 to resurface and $1,466,000 to re-construct (Highway Economic Requirements System, 2012).

The City is responsible for maintaining 2,327 lane miles (excluding state routes and highways).  Roughly 8% of these lane miles are in area 11. ​

Budget priorities in the Regional Transportation Plan (RTP) have shifted from new road construction and widening to maintenance of the existing system, with 69% of the current regional transportation budget allocated to maintenance.

Chattanooga typically budgets about $500,000 annually for new sidewalks across the entire city, which only pays for about a half-mile of sidewalks.


Traffic modeling from the 2045 Regional Transportation Plan shows that congestion is likely to increase on East Brainerd Road and parts of Shallowford Road near the I-75 interchange (see Congestion Map). ​​​

Several factors contribute to congestion in Area 11 including

regional traffic into and out of the area;

a disconnected street network with few route options; and

destinations that are separated from housing and therefore must be reached with a personal vehicle.
