The project is located at the interchange of State Route 210 and I-215 and involved the construction of a new 1 mile segment of freeway with six to eight mix-flow lanes, and two to four HOV lanes

Project Highlights :

• Group Delta Consultants provided a comprehensive geotechnical design report (GDR) for the roadways and structure foundation reports (SFRs) for the bridges and associated MSE walls and tieback walls in accordance with Caltrans guidelines.
• Access ramps mainly on fill embankment
• Based on the results of our fault-rupture investigation, about 8-inch fault displacement (both vertical and horizontal) was recommended for the design of structures in the interchange area
