History and Background

Apison Pike provides a connection between the Chattanooga suburbs of Ooltewah, Collegedale, and Apison, as well as access to Enterprise South Industrial Park, Southern Adventist University, McKee Foods, and Collegedale Municipal Airport.

The majority of the existing route is a two-lane highway with negligible shoulders. The section between Ooltewah Ringgold Road and Layton Lane will be reconstructed, shifting nearly half of the route to the north of the existing roadway. The new alignment will be a five-lane facility, allowing for two lanes in each direction with a dedicated center turn lane.

A new intersection will be built at Tallant Road with a roundabout design.

A new bridge will be built over the Norfolk Southern Railroad to separate the tracks from the state route. In total, construction will include five (5) bridges, as well as nine (9) walls, along the route.

Additionally, 4-foot bike lanes and 5-foot sidewalks will be constructed along both sides of the roadway.
