It’s a familiar scenario-a busy urban highway in need of expansion. The width of the highway, however, is restricted by limited right-of-way, and high land values prohibit increasing the right-of-way. So what choice does the designer have? To go vertical, but elevated lanes require bridges or filled approaches and depressed lanes require earth cuts. In Texas, cantilever precast concrete (CPC) retaining walls have proven a viable option for supporting the lateral loads caused by filled approaches and earth cuts.
