Highway in Louisiana

Interstate 110 (I 110) is an auxiliary Interstate Highway in the U. S. state of Louisiana. It runs 9.06 mile (15 km) in a north–south direction as a spur of I 10 in the city of Baton Rouge. The route branches off of I 10 just east of the Horace Wilkinson Bridge across the Mississippi River and travels along an elevated alignment between the city's downtown area and Mid City neighborhood. The interstate then makes two degree turns, the first occurring in front of the Governor's Mansion a few blocks east of the State Capitol. In the northern portion of the city, I 110 engages in a stack interchange with the concurrent U. S. Routes 61 (US 61) and 190 (US 190, Airline Highway) and passes just west of the Baton Rouge Metropolitan Airport. The highway terminates as traffic merges onto US 61 (Scenic Highway) in an area known as Scotlandville. I 110 began as a short section of independent freeway near the downtown area originally known as the Baton Rouge Expressway. It opened to traffic in 1957 and served as part of US 61/190 Bus. until 1960. At this time, the route was incorporated into the Interstate Highway System as I 410 and was intended as part of a northern bypass of I 10 utilizing the existing Mississippi River Bridge on US 190. This project was cancelled in the mid 1960s, and the highway was instead utilized as a spur and renumbered as I 110. The highway was then extended northward in stages until its completion near Southern University in 1984. In 1999, the Louisiana legislature designated I 110 as the Martin Luther King Jr. Expressway.

From the south, I 110 begins at a three leg directional interchange with I 10 at exit 155B. I 10 branches west from this junction across the Mississippi River via the Horace Wilkinson Bridge and southeast toward the city of New Orleans. I 110 heads north as an elevated six lane freeway, dividing the downtown and Mid City areas of Baton Rouge. A number of closely spaced and overlapping interchanges provide access to surface streets below, including: exit 1A to LA 73 (Government Street); 1B to Convention Street; 1C to US 61/190 Bus. (Florida Street); 1D to North Street; and 1H to Laurel Street. Most of the above are left exits favoring northbound traffic. I 110 briefly passes through the Spanish Town neighborhood as it descends to grade and bends sharply due east in front of the Governor's Mansion. Here, exit 1E connects with LA 3045 (Capitol Access Road), leading to the State Capitol, Capitol Park, Old Arsenal Museum, and Louisiana Department of Transportation and Development headquarters. The highway then passes the BREC Memorial Sports Complex, accessed via exit 1F to Fuqua Street, and has partial interchanges with Scenic Highway (2A) and LA 67/North 22nd Street (2B). After curving back to the north, I 110 elevates again and travels for 3 mile (5 km) through a residential neighborhood located just east of a large industrial area. Tight diamond interchanges during this stretch provide access to Chippewa Street (exit 3A), Mohican Street and Wyandotte Street/Weller Avenue (3B), Evangeline Street (4), and Hollywood Street (5A). The posted speed limit is through the downtown area, after which it increases to for the remainder of the route.

The genesis of the present I 110 was a short stretch of freeway constructed in the mid 1950s called the Baton Rouge Expressway. The first section extended roughly 1 mile (2 km) between Boyd Avenue (now Spanish Town Road) and Plank Road. Traffic was fed onto the expressway from the downtown area via the one way couplet of North 9th and 10th Streets, a continuation of the divided thoroughfare of East Boulevard. It was given the internal designation of LA 3022 and also served as part of US 61/190 Bus. from its opening on August 20, 1957 until 1960.

In 1960, US 61/190 Bus. was moved onto its present route, and the Baton Rouge Expressway became part of the newly designated I 410. By 1963, the expressway was extended south to Government Street. The connections to I 10 were made when the adjoining sections of that highway were completed eastbound to Perkins Road in September 1964 and westbound across the Mississippi River in April 1968. I 410 was intended as a northern beltway extending from I 10 west of Port Allen, crossing the Mississippi River via the existing Huey P. Long Bridge on US 190, and then traveling along the present route of I 110 southward to rejoin I 10. This plan was scrapped around 1965, and the Baton Rouge Expressway was renumbered as I 110 to reflect its function as a north–south spur.

Further northern extensions of I 110 were opened as follows: from LA 67 (Plank Road) to Hollywood Drive around 1969, to US 61/190 (Airline Highway) in 1976, to LA 408 (Harding Boulevard) in the late 1970s, and to LA 19 around 1982. The final segment between LA 19 and US 61 (Scenic Highway) in Scotlandville was completed in January 1984. In total, I 110 was constructed over the course of 30 years at a cost of $94.8 million. The proposal also met with strong opposition from the outside, including Louisiana House of Representatives member and then gubernatorial candidate David Duke, who opposed naming any street for King, stating that his "reputation as a womanizer means the honor is an insult to women and family life." Representatives from the Taxpayer Education Association of Louisiana, the Louisiana Coalition for Conservatism, and the National Association for the Advancement of White People likewise brought up allegations of widespread plagiarism in King's writings and his ties to Communism. Nevertheless, the bill was signed into law that year by Governor Buddy Roemer, designating I 110 as the Martin Luther King Jr. Expressway. Signs bearing the name were not installed along the highway until June 1999.
