SHA Statewide Outdoor Advertising Control Program

While driving along Maryland interstates and other highways you will notice off-premise outdoor advertising signs erected on private property. For many, these signs serve as a great source of information for the traveling public; such as advertising products and services from the business community. All of these signs are regulated and permitted by the Maryland State Highway Administration (SHA). The regulation of these signs helps SHA to manage the outdoor advertising signs, avoid utility lines and waterways, maintain adequate sight distance, and promote the safety and beauty of Maryland’s roads.
It is Maryland’s responsibility to adhere to regulations and policies outlined by the Federal Highway Administration (FHWA), Code of Maryland Regulations (COMAR), Manual of Traffic Control Devices (MUTCD), and the Annotated Code of Maryland. They would include routes maintained by SHA and the Maryland Transportation Authority.  The SHA maintains all-numbered routes along with the Maryland Transportation Authority (MDTA) which manages eight toll facilities including Interstate 95 north of Baltimore to the Delaware State line and the Intercounty Connector (ICC). 
All off-premise outdoor advertising signs must conform to all Federal/State laws and be approved by the local government offices. To learn more about the outdoor advertising regulations, obtain an outdoor advertising sign permit, receive information, or pay an invoice, contact the Office of Real Estate at the SHA headquarters office:
