Miss. Code § 65-1-171
Pursuant to federal appropriations for transportation system improvements, the Mississippi Department of Transportation is hereby authorized and empowered to construct a road and bridge along the following route: Begin at or near North State Street in the City of Jackson's central business district and extend in an easterly direction across the Pearl River to Mississippi 475 at or near the entrance to the Jackson International Airport, for a total distance of approximately 4.6 miles. Final roadway alignment will be determined by a feasibility study.
To defray the cost of the project, the department shall utilize only monies made available to it from the boards of supervisors and the governing authorities of the counties and municipalities within which such project is located; however, the department may utilize state funds to match any federal funds which are specially provided for preliminary engineering, right-of-way acquisition and construction for the connections between I-55 and Mississippi 475 at or near the entrance to the Jackson International Airport, in addition to those federal funds with obligational authority as are regularly apportioned and appropriated to the State of Mississippi for highway purposes. Accessory improvements shall be made to local streets to accommodate traffic generated by the project. All improvements shall conform to congressional appropriations enacted for planning and construction of the project.
