Louisiana Highway 64 (LA 64) is a state highway located in southeastern Louisiana. It runs {{convert|20.45|mi|km}} in a general east–west direction from LA 964 in Zachary to the junction of LA 16 and LA 1026 north of Denham Springs.

The highway traverses the northern portion of East Baton Rouge Parish and connects Zachary and Central, two suburban cities located outside of Baton Rouge. LA 64 also provides the only highway crossing of the Amite River between Grangeville, {{convert|16|mi|km}} to the north, and Denham Springs, {{convert|5|mi|km|spell=in}} to the south. LA 64 reaches the bridge by way of a {{convert|5|mi|km|adj=on|spell=in}} concurrency with LA 37 through Greenwell Springs, a rural community now within the city limits of Central. LA 64 continues into Livingston Parish to connect with LA 16 between Denham Springs and Watson.

LA 64 was created in the 1955 Louisiana Highway renumbering from portions of several former state routes. Much of the route is proposed to be turned over to local control as part of the Louisiana Department of Transportation and Development (La DOTD) road transfer program. In 2015, a section of LA 64 near its western terminus was relinquished, causing a gap in state maintenance that led to the creation of LA 64-1.

Route description

Zachary to Central

From the west, LA 64 begins at the intersection of LA 964 (Old Scenic Highway) and Mt. Pleasant–Zachary Road, both of which lead to US 61 and the city of Baton Rouge. LA 64 heads east through the East Baton Rouge Parish city of Zachary on Church Street, a divided four-lane thoroughfare, and passes several residential subdivisions. Just before the highway passes the local high school, the median is discontinued as the roadway narrows. LA 64 becomes a commercial corridor as the route curves southeast onto High Street then east again across the Canadian National Railway (CN) line onto Main Street.^[2][3][4]

In the center of Zachary, LA 64 intersects LA 19, connecting with Slaughter to the north and Baker to the south. After passing Lane Regional Medical Center, the median reappears, and the highway proceeds through the less developed east side of town. Here, LA 64 intersects LA 67 (Plank Road) in an area known as Fred, connecting with Baton Rouge to the south and Clinton to the north.^[2][3][4]

Central to Livingston Parish

Narrowing to an undivided two-lane highway, LA 64 bends to the southeast and crosses the Comite River into the city of Central, an incorporated collection of rural communities and residential subdivisions. The first community is known as Deerford and is located around the junction of LA 64 and LA 410 (Blackwater Road). The highway maintains a southeastern trajectory for the next {{convert|5.2|mi|km}} to a T-intersection with LA 409 (Liberty Road) at Indian Mound. LA 64 turns south to a second T-intersection with LA 37 (Greenwell Springs Road), and the two highways proceed southward concurrently through the community of Greenwell Springs, still within the city of Central.^[2][3][4]

Passing the local post office, LA 37-64 intersects LA 408 (Hooper Road), the area's main connection to Baton Rouge Metropolitan Airport. Running parallel to the Amite River, the route continues southward for another {{convert|2.9|mi|km}} to LA 3034 (Magnolia Bridge Road) in Magnolia. Here, LA 64 turns east while LA 37 continues ahead on Greenwell Springs Road toward Baton Rouge. LA 64 proceeds as an undivided four-lane highway across the Amite River via the Magnolia Bridge, simultaneously crossing out of East Baton Rouge Parish and the city of Central and into unincorporated Livingston Parish.^[2][3][4]

In Livingston Parish, LA 64 narrows again to two lanes and passes the community of Plainview, located along LA 1019. LA 64 reaches its eastern terminus at a junction with LA 16 between Denham Springs and Watson. The highway continues across LA 16 as LA 1026 (Lockhart Road) toward the small city of Walker.^[2][5][6]

Route classification and data

LA 64 is classified by the Louisiana Department of Transportation and Development (La DOTD) as an urban minor arterial within Central and as an urban principal arterial otherwise. Daily traffic volume in 2013 peaked at 25,800 vehicles in Zachary and 20,100 in Livingston Parish. The lowest figure reported was 4,800 vehicles over the LA 37 concurrency in Central.^[7] The posted speed limit is generally {{convert|45|mph|km/h|abbr=on|round=5}}, reduced to {{convert|35|mph|km/h|abbr=on|round=5}} through Zachary. However, the more rural areas allow a speed limit of {{convert|55|mph|km/h|abbr=on|round=5}}^[2]

History

Pre-1955 route numbering

In the original Louisiana Highway system in use between 1921 and 1955, the modern LA 64 was part of several different routes, as follows: State Route 272 from the western terminus to Fred; State Route 884 to Deerford; State Route 276 to Indian Mound; State Route 37 to Magnolia; State Route C-1766 across the Amite River; and State Route 334 in Livingston Parish.^[8][9] (Route 37 was one of the few pre-1955 state routes that retained the same number after the 1955 Louisiana Highway renumbering.) The entire above route was graveled by 1930.^[10][11] Paving began at the west end of the route and was completed through Zachary to Fred in 1937.^[12][13] The paving project smoothed out some sharp bends in the roadway on the east side of Zachary.^[10][13] The portion of the route between Indian Mound and Magnolia was paved in 1940 as part of an improvement project along State Route 37.^[14][15] Paving resumed eastward from Fred a decade later and was completed past Deerford by 1953^[16][17] and to Indian Mound shortly after the 1955 renumbering.^[18][19] The remaining gravel portion of the route east of Magnolia was also hard surfaced around 1956.^[18][19]

Post-1955 route history

LA 64 was designated in the 1955 renumbering, creating a continuous route from what was then US 61 (now LA 964) west of Zachary and across the Amite River into Livingston Parish.^[18][20] Shortly after the 1955 renumbering, the route was extended west a short distance to Samuels Road, a gravel portion of LA 68 that would become the current alignment of US 61, bypassing the Old Scenic Highway alignment once improvements were completed in 1961.^[21][22] This extension, a gravel road itself until the mid-1960s,^[23][24] ran parallel to the Port Hudson–Plains Road, which was originally designated as part of LA 64. It connected with the remainder of the route by way of a concurrency with former US 61, as described in the official route description. After LA 64 was re-routed, the Port Hudson–Plains Road remained in the state highway system as LA 3004 until it was ultimately returned to local control.

With the 1955 renumbering, the state highway department initially categorized all routes into three classes: "A" (primary), "B" (secondary), and "C" (farm-to-market).^[25] This system has since been updated and replaced by a more specific functional classification system.

Small realignments have occurred on LA 64 over the years, mostly from the construction of new bridges along the route. The Magnolia Bridge Road was realigned and straightened when a new bridge across the Amite River was built in 1955.^[26][27] (This bridge has since been replaced by a new four-lane span.) A curve at Indian Mound was smoothed out when a new bridge was constructed on LA 37 across nearby Sandy Creek in 1957.^[8][28] The bypassed curve is now a local road known as Old Greenwell Springs Road. In 1978, a zigzag east of Zachary was eliminated with the opening of a new bridge across the Comite River.^[27][29] (Jodie Road and Tucker Road are remnants of the original alignment here.) Around this same time, the portion of LA 64 running through Zachary was widened to four lanes, increasing the traffic capacity through this growing suburb.^[30][31]

In 2015, LA 64 was shortened on its west end when {{convert|1.4|mi|km}} of the route west of LA 964 was returned to local control, leaving a section of road adjacent to US 61 disconnected in terms of state maintenance. This portion of former LA 64, {{convert|2.0|mi|km}} in length, was renumbered as LA 64-1.^[1]

Future

La DOTD is currently engaged in a program that aims to transfer about {{convert|5000|mi|km}} of state-owned roadways to local governments over the next several years.^[32] Under this plan of "right-sizing" the state highway system, the entire route of LA 64 west of Indian Mound and the LA 37 concurrency is proposed for deletion as it does not meet a significant interurban travel function.^[33]

Major intersections

Auxiliary route

Louisiana Highway 64-1 (LA 64-1) runs {{convert|1.98|mi|km}} in an east–west direction between US 61 and a local road west of Zachary. It was part of LA 64 until a portion of the Mt. Pleasant–Zachary Road was returned to local control in 2015, leaving a gap in state maintenance.

From the west, LA 64-1 begins at a point on US 61 (Samuels Road) between Baton Rouge and Port Hudson. It heads east along Mt. Pleasant–Zachary Road as an undivided two-lane highway for {{convert|2|mi|spell=in}} to an intersection with Barnett Road. Mt. Pleasant–Zachary Road continues as a local road into the city of Zachary. State maintenance resumes at LA 964 (Old Scenic Highway), the western terminus of LA 64.^[3][4][34]

LA 64-1 is classified as an urban principal arterial by the Louisiana Department of Transportation and Development (La DOTD). The average daily traffic volume on this roadway was reported as 7,500 vehicles in 2013.^[7] The posted speed limit is {{convert|55|mph|km/h|abbr=on|round=5}}.^[34] LA 64-1 is proposed for return to local control as part of the La DOTD's ongoing road transfer program.^[33]
