Baton Rouge Expressway 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 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.
Interstate 410 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.
Renumbering and extensions 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. ==Exit list==
