The US 183 South / Bergstrom Expressway project will improve safety, optimize system connectivity, and enhance local mobility along the US 183 corridor. The project extends eight miles from US 290 to SH 71 in east Austin. When completed, the new expressway will serve as a gateway to Austin-Bergstrom International Airport and as a bypass to Interstate 35. It will reduce travel times and improve mobility for commuters, local drivers, visitors to the region, and people who prefer to use public transit, ride their bike or walk.
MRA was part of the project development team that developed a comprehensive approach to design known as CSS (Context Sensitive Solutions), which was a 16-month planning and public input process that resulted in a set of aesthetic guidelines for the project. This approach allowed for public input to influence the final design such that it reflects the community's cultural and historic values and aesthetic preferences.
The project includes a variety of features designed by MRA, including distinctive V-shaped supports for the overpasses, visual screens, vehicular and pedestrian bridges, and precast concrete sound walls. Early in the project's conception, MRA also designed concepts for a signature bridge ranging from a parametric 3D-printed concrete span to a suspension bridge supported by two steel-framed pylons to a pedestrian overpass composed of steel arches and tubes.
