Louisiana Highway 42 (LA 42) is a state highway in Louisiana that serves East Baton Rouge, Ascension, Livingston, and Tangipahoa parishes. It spans 47.8 miles (76.9 km) in a general east–west direction.

A state highway, state road, or state route is usually a road that is either numbered or maintained by a sub-national state or province. A road numbered by a state or province falls below numbered national highways in the hierarchy. Roads maintained by a state or province include both nationally numbered highways and un-numbered state highways. Depending on the state, "state highway" may be used for one meaning and "state road" or "state route" for the other.

Louisiana is a state in the Deep South region of the South Central United States. It is the 31st most extensive and the 25th most populous of the 50 United States. Louisiana is bordered by the state of Texas to the west, Arkansas to the north, Mississippi to the east, and the Gulf of Mexico to the south. A large part of its eastern boundary is demarcated by the Mississippi River. Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties. The state's capital is Baton Rouge, and its largest city is New Orleans.

East Baton Rouge Parish is the most populous parish in the U.S. state of Louisiana. As of the 2010 census, the population was 440,171. The parish seat is Baton Rouge, Louisiana's state capital.

The current LSU main campus was dedicated in 1926, consists of more than 250 buildings constructed in the style of Italian Renaissance architect Andrea Palladio, and occupies a 650-acre (2.6 km²) plateau on the banks of the Mississippi River.

From this intersection, LA 42 turns east and follows Highland Road to US 61 (Airline Highway). In this segment, it passes the Highland Road Park and Observatory and the Louisiana Country Club. Curving to the northeast, LA 42 widens to four lanes and passes through an interchange with I-10 (exit 166).^[1]
