EXECUTIVE SUMMARY This project is a redesign of Interstate 44 located in Rolla, Missouri between the Highway 63 and Highway E interchanges, including a redesign of the Highway E interchange. AEF Consultants has given top priority in setting the design speed of the interstate to be 70 mi/h. Therefore, the recommend changes include acquisition of nearby property and a considerable volume of cut material. Furthermore, the section of highway beneath the Vichy Road Bridge cannot be raised due to the current low clearance, so displaced fill cannot be simply relocated. The overhaul costs alone are estimated to be $12,299,525. As a result, the overall project cost is estimated to be $16,752,370. 2

INTRODUCTION This project is a redesign of I-44 in Rolla, Missouri, between the interchanges of Hwy. 63 and Hwy. E. It also includes a redesign of the Hwy. E interchange, shown in Figure 1. This specific stretch was constructed in 1953 and has since been overlaid in ’64, ‘78, and ’84. Due to the overlays, the Vichy Road Bridge clearance is reaching a critical level. Furthermore, its deck has a state rating of 3. At current, the 5-year average accident rate is 376.67 and the state-wide average for a similar road is 120.78. Despite having the speed limit lowered to 60 mi/h, drivers do not obey the traffic signals and the accidents have not waned. This specific section of highway is important for several reasons. First, it is a major economic corridor through the Midwest and also of direct service to the cities of St. Louis, Joplin, Rolla, and Springfield. Furthermore, it serves as a vital route to and from Fort Leonard Wood. Finally, specific items of interest to Rolla include service to local, state, and federal agencies as well as a major route to Missouri S&T, a handful of major employers, wholesale companies, and retail businesses, and a number of additional vital support services (MoDOT). 3

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
