There is a long history of mass transportation in Zanesville. This history began in the latter part of the 1800's, when streetcars and trolleys traveled the famous Y-Bridge as the city served as Ohio’s state capital. Privately owned mass transportation survived in Zanesville until the early 1960's.
In 1961 the Zanesville Mass Transit Company gave notice that they would cease operations when the franchise expired in 1962. Operating costs were exceeding the fare box revenues. Local residents rallied by selling stock at $10.00 per share. In only three months, over $34,000 was raised to save the city’s transit service.
Through these efforts, Y-City Transit was born. The system operated eight (8) routes with thirty (30) minute headways. Federal funding, pursuant to the Urban Mass Transportation Assistance Act of 1964 helped recapitalize the system. Still, continuing operation deficits led to the failure of Y-City Transit in May of 1977.
The Muskingum Authority of Public Transit (MAPT), which was created on September 24, 1979 by the City of Zanesville and the village of South Zanesville, is a public body created by Chapter 306, sections 30-71 of the Ohio Revised Code and is owned by the taxpayers of Muskingum County. It is financed by Federal, State of Ohio, and local funding. It is the intention to provide residents a continued, uninterrupted public transit service. Operations began in 1980. In January 2000, MAPT legally changed its name to South East Area Transit (SEAT).
Today, SEAT offers three (3) fixed route services in Zanesville and two (2) fixed route services in Guernsey County, E&D ADA (curb-to-curb Para transit service), and County Wide demand response service.
