Louisiana Highway 434 (LA 434) is a state highway in Louisiana that serves St. Tammany Parish. It spans 10.3 miles (16.6 km) in a south to north direction. South of US 190, it is known as Lake Road.

Route description[edit]

From the south, Lake Road begins at Lake Pontchartrain shoreline. The state maintained portion which is designated as LA 434 begins about two miles (3.2 km) from the lake at the intersection of Barringer Road and Lake Road. LA 434 continues northward to a junction in Lacombe with U.S. Route 190 and LA 1093-1. At this point, it turns northeastward onto US 190 and the roadways overlap as they cross Bayou Lacombe together. Shortly thereafter, LA 434 turns northward and eventually intersects Interstate 12 at a diamond interchange (exit 74). It continues northward through the community of St. Tammany to a terminus at LA 36.

LA 434 is an undivided, two-lane highway for its entire length.

Major junctions[edit]

The entire highway is in St. Tammany Parish.
