Which organization manages tax-exempt properties used for projects by the New Jersey Highway Authority?

The New Jersey Highway Authority manages tax-exempt properties used for its projects, which includes toll roads and other infrastructure developments related to transportation. This organization not only oversees the operation and maintenance of highway facilities but also determines the relevant tax status for properties associated with its projects.

The other options, while related to infrastructure and transportation in New Jersey, do not have the specific mandate to manage tax-exempt properties linked directly to the New Jersey Highway Authority. The New Jersey Turnpike Authority, for example, operates the New Jersey Turnpike and the Garden State Parkway but focuses more on toll road operations rather than the broader scope of tax-exempt property management associated with highway projects. The Interstate Commission primarily deals with interstate regional issues and doesn't handle tax management specifically. Similarly, the County Tax Office is concerned with local property taxes, assessments, and exemptions at the county level, rather than managing properties tied to state-level infrastructure projects. Therefore, the New Jersey Highway Authority is identified as the correct organization for this role.
