Louisiana Highway 93

In the original Louisiana Highway system in use between 1921 and 1955, LA 93 was part of three shorter routes: State Route 538 from the southern terminus to Scott;[11] State Route 161 to Sunset;[11][12] and State Route 245 to Arnaudville.[12][13] All three routes originated from various acts of the Louisiana Legislature between 1926 and 1930.[14][15] These highway segments were joined under the single designation of LA 93 when the Louisiana Department of Highways renumbered the state highway system in 1955.[16]

La 93—From a junction with La-US 167 southwest of Lafayette through or near Scott, Vatican, Sunset and Grand Coteau to a junction with La 31 at or near Arnaudville.

— 1955 legislative route description[16]

As the above description indicates, the southern terminus of LA 93 was originally a junction with US 167 southwest of Lafayette. It was located at the modern intersection of Johnston Street and Ridge Road, which is now within the Lafayette city limits. The portion of Ridge Road between US 167 and LA 342 had been a small part of State Route 176 prior to the 1955 renumbering.[11] It became part of LA 93 until being transferred to local control in 2015 as part of La DOTD's Road Transfer program. As of 2018, the portion of LA 93 from US 90 to Dulles Drive is under agreement to be removed from the state highway system and transferred to local control.[17] In the future, the remainder of LA 93 between the roundabout and US 90 in Scott is to be similarly removed from the state highway system.[18] The current southern terminus is located at a roundabout that was constructed in 2003, replacing a standard four-way intersection. It is believed to be the first modern roundabout built in the state of Louisiana and has since been followed by several more within Lafayette Parish.[19]

Since the 1955 renumbering, most changes to LA 93 have involved the smoothing of various zigzags along the route, a typical feature of the rural farm roads the highway was originally aligned with. Several right-angle turns were eliminated between Scott and Cankton prior to 1958.[11][20] At the same time, a short section of highway was constructed in Sunset, reducing the number of right-angle turns heading into town from five to one.[12][21] The original alignment followed Churchill Street, MacArthur Drive, Anna Street, and Landry Street to Napoleon Avenue.

The most significant realignment occurred in Scott, where LA 93 was moved from its original path along St. Mary Street onto Apollo Road. This road had been constructed in 1981 as a truck route officially designated as LA 3168 and co-signed as LA 93 Truck.[22][23] Sometime afterward, St. Mary Street was transferred to local control, and the signage for LA 93 was removed from the route. However, Apollo Road continued to be signed as LA 93 Truck and LA 3168 until new signage identifying the route solely as mainline LA 93 was installed in 2013 in connection with another roundabout project at the junction of Apollo Road and St. Mary Street.[2][24] In 2021, most of LA 93 south of US 90 was retired from the state highway system, with the small remainder becoming auxiliary route LA 93-1.[5]

La DOTD is currently engaged in a program that aims to transfer about 5,000 miles (8,000 km) of state-owned roadways to local governments over the next several years.[25] Under this plan of "right-sizing" the state highway system, the portion of LA 93 south of US 90 in Scott was deleted as it no longer met a significant interurban travel function.[5]

Louisiana Highway 93-1 (LA 93-1) is a 1.819-mile (2.927 km) long auxiliary route of LA 93. When most of LA 93 between LA 342 in Lafayette and US 90 in Scott was decommissioned and transferred to local jurisdiction in 2021, the remaining state-owned highway became LA 93-1. The entire route runs in a north–south direction along Rue de Belier, from a roundabout with the eastern terminus of LA 342 (Ridge Road), to a point immediately south of Dulles Drive in Scott.[1] This was done under the La DOTD's Road Transfer Program to streamline the state highway system by retiring and transferring various non-essential state highways to local jurisdictions. The entirety of LA 93-1 is slated to be retired to local authority in the future, with the northern section undergoing a transition as of 2022.[5][25]
