Louisiana Highway 73 (LA 73) is a state highway in Louisiana stretching from Geismar to Baton Rouge. LA 73 was built as a bypass to the backbends of River Road. It was soon after bypassed itself in a more complete way with U.S. Route 61 (Airline Highway).
From LA 75 (River Road), LA 73 travels north north east as an undivided two-lane road through the Dutchtown area before hitting I-10 and US 61. From US 61 it turns north through Prairieville, Louisiana and turns northwest to cross Bayou Manchac. At one time, this portion of the highway was called Hope Villa Road. For most of its length in East Baton Rouge Parish, LA 73 is known as Jefferson Highway. At Tiger Bend Road it becomes a four-lane with turning lane for about a mile and before becoming concurrent with Airline Highway for another mile. After leaving Airline Highway it takes a generally northwesterly path until it becomes Government Street at the entrance to downtown Baton Rouge. As Government Street it proceeds due west to a junction with LA 991 (River Road). LA 73 ends at an intersection with the southbound beginning of LA 30, also known as St. Philip Street.
