Section 250-155-6 - DESIGNATED ROUTES1. Each state will designate those routes over which the envelope vehicles may be routed by other participating states (i.e., the green regional routes).2. Each state is responsible for amending routes as required by construction, etc., and notifying all other participating states of detours or alternate routes no later than 10 working days prior to the changes taking effect, unless an emergency situation occurs which would not allow for that action.3. The state issuing permits for travel will authorize travel only on those routes designated by the participating states. When issuing a permit where the origin state and destination state are both parties to the Agreement, the permit issuing state will coordinate local origin routing with the permit office of the origin state. Coordination is not required for local origin routing in cases where the permit is issued to a major generator of permit loads and the local origin routing has been previously approved for envelope size loads.4. The multi-state permit contains a space on which the acceptable routes of travel will be clearly designated for a specific envelope vehicle. No deviation from the designated route is allowed unless an approved alternative route is required as determined by a particular state. When a particular load must use highways under local jurisdiction (off the State Highway System), the carrier operating the vehicle must obtain the local permits required. Section 7 below, provides more details.29- 250 C.M.R. ch. 155, § 6
