The 2018 Traffic Control Plans are the most recent revision of previous plans used by MTA Maintenance forces. These plans are updated periodically and are used by MTA maintenance forces for setting up needed traffic control for planned maintenance activities. They are also available to others who may need to set up traffic control on the Turnpike as guidance to what might be acceptable to the MTA. Any Traffic control set up on the MTA must be pre-approved by MTA engineering.
