MS 607 is part of two scenic routes and memorial designations: Hospitality Highway, which is designated from I-10 to US 90, and NASA Scenic Byway to Space, starting at the intersection of MS 607 and MS 604 to the south gate of the center, then from the north gate to Texas Flat Road. History The road that became part of MS 607 was part of US 90 and US 11 since 1928, and all of it became paved by 1934. In 1936, a new road was built from US 90 to south of Slidell, and US 90 was soon rerouted to it. The road between US 11 and US 90 became MS 11-90. By 1939, US 90 was moved to another new road, bypassing the old one. The MS 11-90 designation was temporarily removed in 1942, and was restored the next year. In 1948, MS 11-90's designation was removed, and the road became part of MS 43. Between 1958 and 1960, I-59 and I-10 were proposed. Meanwhile, the United States Army Corps of Engineers began buying land in Hancock County for the Mississippi Test Operations in 1962, which later became Stennis Space Center. In 1967, MS 43's alignment was moved around NASA's test site, and the old alignment became MS 607. Only north and south of the test area were state maintained. Construction at the test facility was completed later that year. By January 1971, I-10 was connected to MS 607. One month later, MS 607 south of the Stennis Space Center was upgraded to a four-lane divided highway, after it was proposed in 1969. A project to widen MS 607 from Texas Flat Road to I-59 began in 2013, and construction continued through 2015.
