Downtown Louisville commuters and local workers are facing significant travel adjustments as a key thoroughfare temporarily shuts down for major infrastructure improvements. Beginning September 14, motorists traveling through the downtown area are being instructed to navigate newly established detour routes as work gets underway on a critical segment of Broadway beneath Interstate 65.
Officials overseeing the I-65 Central Corridor Project have confirmed that this central roadway will remain closed to all traffic until at least early October. The shutdown is required to allow construction teams sufficient space and safety clearances to carry out the complete demolition and preliminary rebuilding of the aging interstate overpass overhead.
The disruption is not limited to Broadway alone. Project managers noted that vehicular travel along Gray Street underneath the I-65 structure has also been temporarily halted through early October. While motor vehicles are barred from using this stretch of Gray Street, transportation planners confirmed that pedestrian pathways through the corridor will remain open and accessible throughout the duration of the demolition.
To maintain traffic flow across downtown Louisville during this construction phase, regional planners have established separate detours for both directions along Broadway. Commuters traveling westbound are instructed to initiate their detour at South Preston Street, follow it southward until reaching East Breckinridge Street, turn west onto South Second Street, and subsequently proceed north to merge back onto Broadway.
Motorists heading along the eastbound corridor of Broadway must follow an alternative designated path. Eastbound traffic will be redirected beginning at South First Street, with drivers heading south toward East College Street before turning northward onto East Brook Street, which will ultimately guide them back to their primary route on Broadway.
In conjunction with the local surface street closures, travelers along the main interstate will encounter additional nighttime delays. The Kentucky Transportation Cabinet has scheduled overnight lane reductions along Interstate 65 between Jacob and Floyd streets. These intermittent interstate lane closures are slated to run from 9 p.m. to 6 a.m. between September 13 and September 18.
Maintaining reliable and direct access to essential healthcare services in downtown Louisville has been highlighted as a critical priority during the construction period. Officials emphasized that routes leading to local downtown medical facilities and hospitals will remain accessible throughout the prolonged closures on both Broadway and Gray Street.
For drivers who are exiting northbound Interstate 65 at the Broadway exit but are not seeking medical care, specific alternate instructions have been issued. These non-medical motorists are instructed to execute a right-hand turn onto Broadway and continue heading northward into the downtown core by traveling along Clay Street.
Transportation officials have also issued broader travel advice for everyday commuters who do not have destinations within the medical core. A formal statement from project representatives urges non-hospital traffic to seek alternative pathways entirely, specifically requesting that motorists avoid the sections of Brook Street, Floyd Street, and Chestnut Street that sit in close proximity to the work zones.
The closure of Broadway was initially scheduled to take place weeks earlier, on August 26. However, state and local transportation managers decided to delay the start of the demolition after significant traffic congestion emerged across nearby streets, which were already dealing with simultaneous long-term closures on Muhammad Ali Boulevard and Brook Street.
Officials used the postponement period to reassess traffic conditions, revise navigational strategies, and implement necessary adjustments to the Broadway detour routes. Despite these modifications, transportation authorities confirmed that the long-term closures affecting Brook Street and Muhammad Ali Boulevard remain active as construction continues in the area.
The Broadway overpass project represents only one component of a much larger modernization effort currently underway across the city. According to state infrastructure plans, the Broadway structure is one of six different overpasses throughout Louisville that are scheduled to undergo complete replacement by the end of 2027.
While local streets are experiencing significant localized closures, transportation planners have emphasized that no full shutdown of the Interstate 65 corridor itself is planned during this stage of the project. This contrasts with earlier phases of work, which required an entire five-mile section of the corridor to be completely shut down for approximately two months during the summer of 2026.
Looking ahead, long-term lane constraints will continue to affect regional travel as broader bridge rehabilitations proceed. Kentucky Governor Andy Beshear announced on September 10 that a one-mile segment of Interstate 65 near downtown Louisville will be narrowed to just a single lane of traffic, a restriction expected to begin around May 2027 and extend into late 2028.
