Section 420-2-11 - Location of Sign Assemblies1.MAINLINE SIGN ASSEMBLIESA. Mainline sign assemblies shall be erected between the previous interchange and at least 800 feet in advance of the first exit direction sign closest to the interchange from which the services are available. There shall be at least 800 feet spacing between the logo sign assemblies and other highway signs.B. If a service meets the criteria for approval at more than one interchange, signing will be allowed only from the exit providing the most direct route in each direction.C. Once services are selected for a particular assembly, the first approved service from which an application was received will have its sign placed on the top left of the assembly and the second service facility of the same type will be on the next space horizontally. In cases where two types of services are combined on the same assembly , logos will be arranged with similar services grouped horizontally and the following priority of services displayed from top to bottom: lodging, camping, and attractions.D. The number of sign assemblies shall be limited to one for each type of service along an approach to an interchange. At double exit interchanges the top section shall display logos for the first exit and the lower section shall display logos for the second exit. Specific service signs at double exit interchanges shall be limited to four logos each and shall be displayed successively in the direction of travel in the following order: camping, lodging, and attractions. 2.RAMP SIGN ASSEMBLIESA. Ramp sign assemblies shall be installed along the ramp for service facilities which have logos displayed along the interstate unless the service is readily visible from the ramp terminal or if there is only one direction of travel possible at the end of the ramp and the service is less than 1/2 mile from the end of the ramp. Logos on ramp signs shall be duplicates of the corresponding logos installed along the main roadway and shall be grouped in the same manner as mainline signing. Ramp sign assemblies shall include distances to the nearest mile to the service if located more than 1/2 mile from the exit ramp. Directions shall be indicated by arrows.B. Signs along the ramp shall be installed on the right side of the ramp, unless circumstances, including but not limited to physical layout and visibility, require left side installation. Spacing shall be provided between all ramp sign assemblies and between ramp sign assemblies and other highway signs to provide motorists adequate time to read all the messages on the ramp.99-420 C.M.R. ch. 2, § 11
