Louisiana Highway 37 (LA 37) is a 42.7-mile-long (68.7 km) north-south state highway in Louisiana, United States, extending from Wooddale Boulevard in Baton Rouge to Louisiana Highway 10 in Greensburg.^[1] In East Baton Rouge Parish, the highway is named Greenwell Springs Road.

Route description

From the southwest, LA 37 begins just west of a cloverleaf interchange with US 61/US 190 in the city of Baton Rouge. The highway heads northeast along Greenwell Springs Road and, about a mile after exiting the city limits, curves northward. Now running parallel with the Amite River, LA 37 begins a concurrency with LA 64 that lasts through much of Central, a newer city that encompasses smaller communities such as Greenwell Springs. North of Central, LA 37 follows the west bank of the Amite River until sharing a bridge across the river with LA 63. After a short distance, LA 37 leaves the river's path and heads northeast through rural St. Helena Parish to its terminus at LA 10 in Greensburg.^[1]
