Section 250-155-5 - REGIONAL HIGHWAY NETWORK1. The Agreement States have developed a regional state highway network as the designated state administered routes over which the envelope vehicles are permitted to travel in accordance with this Agreement. When the issuing State issues a multi-state permit, the permit will designate the route(s) within each state over which that specific envelope vehicle and/or load may travel. No other routes may be used in order to make the trip for which a multi-state permit has been issued.2. A Regional Highway Network Map showing the designated system is available from the Overlimit Permit Unit.3. Each time a temporary restriction must be put into effect, and when the restriction is ready for removal from the map, the individual state will notify the other Agreement States as quickly as possible of that event.4. When the Issuing State issues a multi-state permit for an envelope vehicle, there is no need to obtain permission from another state or states when all the conditions of the Agreement are being met and the designated Regional Highway Network is being used.5. If a truck operator must gain access to or from a point which is not located on the approved network, the Issuing State may either contact the appropriate State for special instructions to gain that access when issuing the permit or require the carrier to obtain a separate permit from the State in which travel will occur.29- 250 C.M.R. ch. 155, § 5
