The Maryland Transportation Authority is the state's tolling agency responsible for managing, operating, and improving the state's toll facilities. Officials in Maryland believe that MDTA can finance projects just as well as the private sector can. Through MDTA, the state is able take advantage of its favorable bond rating and use tax-exempt revenue bonds to develop toll facilities, roads, bridges, and tunnels throughout the state. In turn, the state is able to operate the highway and collect toll revenues. States like Virginia that utilize PPP agreements to finance new highways do not have a tolling authority (or an authority as robust as Maryland's) and thus are more likely to turn to public-private partnerships in an effort to finance new highway projects while avoiding an increase in the state's debt capacity.
