T.Y. Lin International (TYLI) served as Prime Consultant to the San Bernardino County Transportation Authority (SBCTA) for the reconstruction of two congested interchanges on I-10 in Fontana, California—the Cherry Avenue and Citrus Avenue Interchanges. Services included preparing final plans, specifications, and estimates (PS&E) and providing construction support.
TYLI designed new westbound loop on-ramps and widened and realigned other ramps for both interchanges. Four overcrossing structures were replaced with wider, longer bridges. Working in conjunction with the Landscape Architecture Branch of California Department of Transportation (Caltrans) District 8, TYLI developed unique aesthetic concepts for the bridges.
The mainline tracks for Union Pacific Railroad (UPRR) are adjacent to the I-10 freeway, resulting in the design of the overhead bridges at both interchanges. TYLI worked closely with UPRR and the Public Utilities Commission (PUC) to process the project.
- To meet strict deadlines, TYLI accelerated evaluation of right-of-way requirements and began preparation of design at-risk.
- Close coordination was required with an auxiliary lane project between the interchanges.
- TYLI's aesthetic bridge treatments became the prototype along the I-10 Corridor.
