=== I-24 SMART Corridor ===
The {{convert|28|mi|km|adj=on}} stretch of I-24 between I-440 (exit&nbsp;53) in Nashville and US&nbsp;231 (exit&nbsp;81) in Murfreesboro is currently in the process of being developed into the "I-24 SMART Corridor" in an effort to address congestion and mobility issues.<ref>{{cite web |title = I-24 SMART Corridor |url = https://www.tn.gov/tdot/projects/region-3/i-24-smart-corridor.html |publisher = Tennessee Department of Transportation |access-date = May 13, 2022 |archive-date = April 17, 2022 |archive-url = https://web.archive.org/web/20220417120338/https://www.tn.gov/tdot/projects/region-3/i-24-smart-corridor.html |url-status = live }}</ref> In recent years, this stretch of I-24 has become the most congested highway corridor in the state, due to the rapid growth of the region. The project pairs this stretch with the adjacent paralleling stretch of US&nbsp;41/US&nbsp;70S (Murfreesboro Road) and all connecting roads in between. The first phase, which ran from October 2018 to December 2021, included the construction of emergency pull-offs, improvements to multiple entrance and exit ramps, the erection of additional roadside [[dynamic-message sign]]s (DMSs), and upgrades to traffic signals along the corridor.<ref name="SMARTtimeline">{{cite web |title = I-24 SMART Corridor Timeline |url = https://www.tn.gov/tdot/projects/region-3/i-24-smart-corridor/timeline.html |publisher = Tennessee Department of Transportation |access-date = May 13, 2022 |archive-date = May 13, 2022 |archive-url = https://web.archive.org/web/20220513053707/https://www.tn.gov/tdot/projects/region-3/i-24-smart-corridor/timeline.html |url-status = live }}</ref> The second phase, which began in March 2022, includes the erection of 67 overhead gantries with signs between mileposts&nbsp;53 and 70 that will display recommended [[variable speed limit]]s and variable lane control signs for each lane.<ref>{{cite news |last1 = Wenzel |first1 = Joe |last2 = Sulek |first2 = Marissa |title = TDOT: Construction to Start on Phase 2 of I-24 SMART Corridor Next Month |url = https://www.wsmv.com/2022/03/25/tdot-construction-start-phase-2-i-24-smart-corridor-next-month/ |access-date = May 13, 2022 |publisher = [[WSMV-TV]] |date = March 25, 2022 |location = Nashville, Tennessee |archive-date = March 25, 2022 |archive-url = https://web.archive.org/web/20220325165223/https://www.wsmv.com/2022/03/25/tdot-construction-start-phase-2-i-24-smart-corridor-next-month/ |url-status = live }}</ref><ref>{{cite news |last1 = McCarthy |first1 = Darby |title = I-24 SMART Corridor Project Begins Phase 2, Lane Closures from Nashville to Murfreesboro Beginning in April |url = https://www.newschannel5.com/news/i-24-smart-corridor-project-begins-phase-2-lane-closures-from-nashville-to-murfreesboro-beginning-in-april |access-date = May 13, 2022 |publisher = [[WTVF-TV]] |date = March 27, 2022 |location = Nashville, Tennessee |archive-date = April 19, 2022 |archive-url = https://web.archive.org/web/20220419110113/https://www.newschannel5.com/news/i-24-smart-corridor-project-begins-phase-2-lane-closures-from-nashville-to-murfreesboro-beginning-in-april |url-status = live }}</ref> The final phase will include the installation of [[ramp meter]]s on certain onramps and the installation of additional [[closed-circuit television]] (CCTV) cameras and DMS boards and [[Americans with Disabilities Act of 1990]] (ADA) improvements along connecting arterials.<ref name="SMARTtimeline"/>
