Maryland Transportation Authority Customer Service Number

Since 1971, the MDTA has been responsible for constructing, managing, operating and improving the State's toll facilities, as well as for financing new revenue producing transportation projects. The MDTA's eight toll facilities-two turnpikes, two tunnels, and four bridges-help keep traffic moving in Maryland. All of the MDTA's projects and services are funded through tolls paid by the customers who use the MDTA's facilities.
