I-215 Improvement Project, Segments 1, 2, & 5, San Bernadino

The I-215 Segments 1, 2, and 5 Improvements project was part of a four-segmented project that widened the I-215 between I-10 to I-210 in San Bernardino County. The project realigned and widened the existing I-215 from 6 lanes to 8 lanes with a HOV lane and a Collector-Distributor (C/D) Road system. Existing interchanges, entrances, and exit ramps were reconfigured and reconstructed. This six-mile project was designed to reduce traffic congestion and improve operational problems associated with existing freeway conditions.

LIN Consulting was responsible for the project’s Intelligent Transportation System (ITS) PS&E. Specific tasks included the design of a temporary freeway fiber optic communication system, installation of new fiber optic communication systems, modification of existing equipment in the fields, hubs, Transportation Management Center (TMC), and the installation of pertinent field equipment, including CMS, CCTV, ramp meters, traffic signals, irrigation controller, and freeway surveillance stations.
