RTG led the PS&E to add direct connectors and other improvements to an existing three-level diamond interchange between two six to eight-lane controlled access tollways which required improvements to two miles of SH 121 and two miles of the DNT. The project was completed on a very condensed schedule requiring constant coordination between both the NTTA and sub-providers. RTG performed all roadway design tasks and PS&E assembly (subproviders designed structures, signals, illumination, ITS, TCP sheet production, and preparation of removal sheets).
