The 2 E Main / N High is a Central Ohio Transit Authority (COTA) bus service in Columbus, Ohio. The line operates on High Street, the city's main north-south thoroughfare.
The 2 replaced High and Main Streets streetcar lines, both of which were early streetcars line in Columbus. These lines initially served Columbus with horsecars, and horse-drawn omnibuses followed a similar route. The horsecars were replaced with electric streetcars around the 1890s, and later with trolleybuses. In the mid-20th century, the trolleybus line was replaced with a bus line similar to the modern-day 2 E Main / N High.
