The Noland Road over I-70 interchange is a prime example of Benesch’s commitment to value engineering and MoDOT’s practical design principles. Benesch performed conceptual, preliminary and final design of the interchange. The final bridge design was a two span (80’-80’) prestressed concrete box-girder design supporting an 85’ roadway plus a sidewalk. Drilled shafts were used for the center bent foundations.
Originally, the conceptual design called for a new Single Point Urban Interchange and the replacement of a railroad bridge west of Noland Road. By applying innovative design techniques such as the tight urban diamond with MSE walls, prestressed concrete box girders and eliminating staged construction, the cost of the project was significantly reduced. The specifically tailored prestressed box-girders addressed project constraints along Noland Road and I-70. This design was acknowledged by MoDOT as the Practical Design Project of the Year.
