Old Hammond Highway - Baton Rouge-Hammond Highway

Baton Rouge-Hammond Highway

Old Hammond Highway is also the name of a road in East Baton Rouge Parish that was part of the original Baton Rouge-Hammond Highway, constructed in the late 1910s and early 1920s. This highway was designated as part of State Route 7 in 1921 and U.S. 190 in 1926. It was bypassed in 1941 when Florida Street was extended from Baton Rouge east to the Amite River Bridge, and both route designations were moved onto the new route. The old route became State Route 7D until the 1955 Louisiana Highway renumbering when it was given its current designation as Louisiana Highway 426 (LA 426).

Another portion of the original Baton Rouge-Hammond Highway was bypassed in 1929 and is known as "Old Baton Rouge Highway." This road is now LA 1040 and runs between Hammond and a point south of Albany.
