Stiver Engineering provided geo-structural engineering services to support the 183 North Mobility Project, Segment 1B, a major highway improvement initiative in Travis County. Our scope focused on ensuring the stability and long-term performance of retaining wall systems throughout the project corridor.
The project involved evaluation and engineering support across more than 13,000 linear feet of retaining infrastructure, encompassing 30 wall sections in a mix of cast-in-place and mechanically stabilized earth systems. The scale of the corridor, combined with the presence of live traffic throughout construction, demanded precise engineering coordination and solutions that could be safely implemented without disrupting active roadway operations.
Stiver Engineering assessed slope conditions, evaluated wall performance, and identified stabilization requirements across each wall section. Where slope stability concerns required intervention, we designed soil nail systems to address geotechnical conditions and maintain construction continuity. Our work also included measures to protect adjacent infrastructure throughout all phases of construction.
Throughout the project, our team coordinated closely with project stakeholders to ensure designs met safety, constructability, and schedule requirements from early design through final implementation.
This project reflects Stiver’s ability to deliver integrated geo-structural engineering solutions for large-scale transportation infrastructure, supporting safe construction execution in complex, high-traffic urban corridors.
