In rail transportation, a rolling highway, or rolling road is a form of combined transport involving the conveying of road trucks by rail. The concept is a form of piggyback transportation.
The technical challenges to implement rolling highways vary from region to region. In North America, the loading gauge is often high enough to accommodate double stack containers, so the height of a truck on a flat car is no issue. However, in Europe, except for purpose built lines such as the Channel Tunnel or the Gotthard Base Tunnel, the loading gauge height is much smaller, and it is necessary to transport the trailers with the tyres about 30 cm above the rails, so the trailers cannot be simply parked on a deck above the wagon wheels. Making the wagon wheels smaller limits the maximum speed, so many designs allowing the trailer to be transported with its wheels lower than the rail wagon wheels. An early approach in France was the kangourou with modified trailers. This technology did not survive, due to the market resistance to modified trailers. Today two designs for these special wagons are in commercial service, "Modalohr" and "Cargobeamer".

Maryland Route 166 (MD 166) is a state highway in the U.S. state of Maryland. The state highway runs 2.71 miles (4.36 km) from Interstate 195 (I-195) in Arbutus north to MD 144 in Catonsville. MD 166 consists of two sections: a short freeway section that serves as a northern continuation of I-195 and provides access to the University of Maryland, Baltimore County (UMBC), and a segment of Rolling Road, a major north–south highway in western Baltimore County. Rolling Road dates to the colonial era as a highway used to transport tobacco from plantations to river ports. North Rolling Road, which connects Catonsville with Woodlawn and Milford Mill, has always been a county highway. South Rolling Road was constructed as a state highway by the early 1920s between what were to become U.S. Route 1 and US 40. Parts of South Rolling Road were transferred to county maintenance after they were severed by the construction of I-95 and a freeway relocation of the southern end of MD 166 in the early 1970s.
