Length	4.74 mi[1] (7.63 km)
Existed	1955–present

Louisiana Highway 176 (LA 176) runs 4.74 miles (7.63 km) in a north–south direction inLafayette, located inLafayette Parish.^[30] It parallelsUS 167, the city's primary north–south highway, from a point near the downtown area to the northern limit atCarencro. (North ofI-10, US 167 is co-signed withI-49.)

The route begins atUS 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 theLouisiana 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 withLA 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.^[30][31][32]

In thepre-1955 state highway system, the current route of LA 176 made up of the entirety of formerState Route 675 andState Route C-1384.^[33] LA 176 was created in the1955 Louisiana Highway renumbering,^[34] but it was originally a short connector betweenLA 94 and the junction of US 90 and US 167 in downtown Lafayette.^[35] 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.^[36][37] 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 andLA 728-8). In 2009, a further re-alignment of routes in the area resulted in the LA 176 designation replacing that of formerLA 728-1, greatly lengthening the route.^[31]

The entire highway is inLafayette Parish.

As its local name indicates, the route was once a small part of the historic Jefferson Highwayauto trail which extended fromNew Orleans toWinnipeg, Manitoba, Canada in the late 1910s and 1920s. When theoriginal state highway system was created in 1921, it became part ofStates Routes 1 and5. In 1926, it also served as part of the original alignment of US 71 until the completion of theO.K. Allen Bridge over theRed River in the 1930s.

LA 180 was created in the1955 Louisiana Highway renumbering,^[34] and its route originally followed the entirety of Jefferson Highway betweenUS 165 Business and US 71.^[41][42] The deleted portion, though no longer state-maintained, retains destination signage directing traffic from US 165 Business toward US 71 and US 165, heading towardShreveport andMonroe, respectively.^[40]
