Interstate 59

Interstate 59 travels just 12.06 miles in the Pelican State from Slidell north to Pearl River and Hancock County, Mississippi. Replacing or overlapping with U.S. 11, I-59 regionally joins the Greater New Orleans area with Hattiesburg, Laurel and Meridian, Mississippi.

The initial segment of Interstate 59 built was the twin bridge structures over the Pearl River at the Mississippi state line. Costing $300,000 and completed in 1958, the spans were built at the site of the relocation of U.S. 11.¹ Contracts for the construction of Interstate 59 underway by 1961 included $3,769,074 for the West Pearl River bridges and approaches and $2,885,149 for a 5.4 mile section from the Pearl River to the Mississippi state line. The scheduled for completion was May 1962.² The 6.4 mile section of I-59 between Pearl River Station to a point one mile into Mississippi opened following a dedication ceremony held on August 2, 1962 at the Pearl River Bridge.³

The subsequent segment of Interstate 59 completed was the 3.5 miles extending south from Pearl River Station. A ribbon cutting ceremony for this stretch took place on July 1, 1963. It cost $3.8 million to construct. The remainder of I-59 south to I-10/12 in Slidell was already under construction in 1963.⁴

Interstate 59 in Louisiana was completed in conjunction with I-10 through Slidell by 1966. Reconstruction of the freeway occurred between 1987 and 1989 and the bridges across the West Pearl River were replaced between 1996 and 1997.
