Louisiana Highway 176

Louisiana Highway 176
Location	Lafayette
Length	4.74 mi (7.63 km)
Existed	1955–present

Louisiana Highway 176 (LA 176) runs 4.74 miles (7.63 km) in a north–south direction in Lafayette, located in Lafayette Parish. It parallels US 167, the city's primary north–south highway, from a point near the downtown area to the northern limit at Carencro. (North of I-10, US 167 is co-signed with I-49.)

The route begins at US 90 and US 167, which run concurrently along Northwest and Northeast Evangeline Thruway, a couplet of one-way streets. LA 176 initially heads northeast along Jefferson Boulevard as an undivided four-lane highway. After three blocks, it turns north onto Moss Street and passes along the west side of Lafayette's City Park, crossing the Louisiana and Delta Railroad (LDRR) tracks immediately afterward. 1.2 miles (1.9 km) later, LA 176 intersects West/East Alexander Street and widens to accommodate a center turning lane. Soon afterward, the highway dips below grade and crosses underneath I-10 just east of Exit 103. LA 176 continues north for 2.2 miles (3.5 km) to an intersection with LA 98 (East Gloria Switch Road) on the Lafayette–Carencro line. LA 98 connects to Exit 2 on I-49/US 167 located 1.0 mile (1.6 km) to the west.

In the pre-1955 state highway system, the current route of LA 176 made up of the entirety of former State Route 675 and State Route C-1384. LA 176 was created in the 1955 Louisiana Highway renumbering, but it was originally a short connector between LA 94 and the junction of US 90 and US 167 in downtown Lafayette. When US 90 and US 167 were moved onto the Evangeline Thruway around 1964, LA 176 took over much of the original route of US 167. For the next 45 years, the route comprised only the portion of Jefferson Boulevard between Evangeline Thruway and the intersection of Simcoe and Surrey Streets (the former junction of LA 94 and LA 728-8). In 2009, a further re-alignment of routes in the area resulted in the LA 176 designation replacing that of former LA 728-1, greatly lengthening the route.

The entire highway is in Lafayette Parish.

Existed	1955–present

Louisiana Highway 180 (LA 180) runs 0.12 miles (0.19 km) in an east–west direction along Jefferson Highway in Pineville, Rapides Parish.

The route is a short connector between US 71 and US 165 at the point where the two highways diverge in Pineville, just north of Alexandria. It is an undivided two-lane highway for its entire length.

As its local name indicates, the route was once a small part of the historic Jefferson Highway auto trail which extended from New Orleans to Winnipeg, Manitoba, Canada in the late 1910s and 1920s. When the original state highway system was created in 1921, it became part of States Routes 1 and 5. In 1926, it also served as part of the original alignment of US 71 until the completion of the O.K. Allen Bridge over the Red River in the 1930s.

LA 180 was created in the 1955 Louisiana Highway renumbering, and its route originally followed the entirety of Jefferson Highway between US 165 Business and US 71. The deleted portion, though no longer state-maintained, retains destination signage directing traffic from US 165 Business toward US 71 and US 165, heading toward Shreveport and Monroe, respectively.

The entire highway is in Pineville, Rapides Parish.

Louisiana Highway 184 (LA 184) runs 3.38 miles (5.44 km) in a north–south direction along Chaffee Road east of Leesville, Vernon Parish. It connects Fort Johnson North, an area within the Fort Johnson U.S. Army base with LA 28, the main highway between Leesville and Alexandria. Though its geographic direction is north–south, LA 184 is signed as an east–west route and treated accordingly in the La DOTD route log.

The route begins at the concurrent LA 8 and LA 28, 4.3 miles (6.9 km) east of US 171 in Leesville. Eastbound LA 28 connects to Alexandria in neighboring Rapides Parish. LA 185 heads south and intersects LA 468 (Slagle Road). 2.5 miles (4.0 km) later, it reaches the guard house at the entrance to Fort Johnson. State maintenance ends a short distance later at an intersection with Pendleton Drive, which leads to a residential area within the base.

In the pre-1955 state highway system, LA 184 was designated as State Route C-2040. LA 184 was created in the 1955 Louisiana Highway renumbering, and its route has remained the same to the present day.

The entire highway is in Vernon Parish.
