TARC is already one of the least-polluting, most sustainable ways to get around Louisville (next to biking or walking)…but now your local transit agency is going even GREENER by replacing some of their older, diesel buses with brand new, all-electric buses!

Over the summer, TARC added six new all-electric buses to Route 4 (4th Street), and they are continuing to roll-out even more in their fleet.

Want to get downtown or down to Iroquois Park with no money or tailpipe pollution?! Well now you can! TARC added six new all-electric buses to Route 4, serving Belknap campus. Like every TARC bus, the new fleet costs those with UofL ID nothing to ride. But these sleek, modern electric buses also cost a lot less for our air quality – eliminating the particulates & pollutants from the old diesel fleet.

They also feature bike racks that can hold up to three bikes at once (the old buses only held two)! Catch one of the new buses along 4th Street every 15 minutes from 4:30am to 1am daily (service starts a little later on weekends/holidays)! Full details here.


These new all-electric buses compliment TARC’s existing downtown “ZeroBus!” TARC’s ZeroBus is a fast charging, all electric bus that produces ZERO emissions at the tailpipe.With over 1o vehicles, Louisville has one of the largest electric bus fleets in the country. 

The buses are powered by batteries located under the bus floor which run for 2 hours and can fully recharge on route in less than 10 minutes. The recharge is automatic via a connection to an overhead system that links to a high-capacity charger. 


Louisville’s electric fleet is an $11 million investment in Louisville’s transportation network in an attempt to lower TARC’s emissions by totally replacing the downtown trolleys – the highest polluting vehicles in TARC’s fleet.  Like the old trolleys, all ZeroBus rides are fare-free for everyone (not just those with UofL ID)!

Hop on a ZeroBus next time you’re downtown and enjoy the absence of polluting diesel fumes on two main routes: 

ROUTE 1 – FOURTH STREET TROLLEY:  Breckinridge St. south of Broadway to the Galt House    

ROUTE 77 – MAIN–MARKET TROLLEY:   Along Main and Market streets between 10th and Campbell streets. Serves the Louisville International Convention Center, Fourth Street Live, NuLu and attractions of the West Main Street Cultural District, including Louisville Slugger Museum, Kentucky Science Center, Frazier History Museum, Muhammad Ali Center .
