US 95/Kyle Canyon

To increase safety and capacity, GCW provided preliminary and final design services for a diverging diamond interchange (DDI) at Kyle Canyon Road (SR 157) and US 95. This was the first new DDI constructed in Nevada. The interchange design included two cast-in-place, post-tensioned, concrete box girder bridges. A critical component was the design of the flood control facilities including a concrete drainage junction structure to connect reinforced concrete boxes.
