State Route 317 (Apison Pike) State Route 321 to Layton Lane
Hamilton CountyThe project along State Route (SR) 317 (Apison Pike), from SR 321 (Ooltewah Ringgold Road) to east of Layton Lane includes realignment and reconstruction for approximately 3.4 miles. The roadway will be widened from two to five lanes. The improvements are intended to correct roadway deficiencies, improve access and increase capacity, thereby improving the safety, efficiency and operation of the roadway.
This project is part of a larger effort to reconstruct and widen Apison Pike from Interstate 75 to East Brainerd Road. To read more about all improvements for the corridor, visit the Apison Pike project website.
Current Status: The section between State Route 321 (Ooltewah Ringgold Road) to east of Layton Lane is currently under construction.
Estimated construction start: March 2020
Estimated completion*: June 2025

Traffic Impacts
PHASE 1 – March 2020 to June 2022
SR 317 (Apison Pike) – Two travel lanes (one lane in each direction) will remain open, but lanes will be shifted to allow for rock drape installation and utility work.

Tucker Road – Traffic may be affected intermittently. Traffic will be flagged when necessary.
Tallant Road – Two travel lanes (one in each direction) will remain open.
PHASE 2 – June 2022 to August 2023
SR 317 (Apison Pike) – Two travel lanes (one in each direction) will remain open, but lanes will be shifted for construction. Temporary traffic signals will be placed at the intersection with Tallant Road.
Spalding Drive – At least one lane will remain open. Traffic will be flagged when necessary.
Tucker Road – Stop signs will be installed at the intersection with proposed Tucker Road.
Tallant Road – Traffic will be shifted to the new alignment with a detour onto Asher Lane until the box culvert under the new Tallant Road alignment is built.
College Drive – Traffic will be detoured to University Drive while the railroad crossing is replaced.
PHASE 3 – August 2023 to June 2025

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.
