Laurel Street/BNSF Grade Separation Project
San Bernardino County Transportation Authority
TranSystems was the prime consultant providing environmental and final design services for the construction of a grade-separated undercrossing of Laurel Street with six BNSF tracks in the City of Colton, California. The construction of this underpass separated vehicular traffic from rail traffic in order to enhance safety, improve local traffic circulation, reduce air quality emissions, and establish a train horn quiet zone within city limits. Several alternatives were developed and evaluated to minimize right-of-way impacts as much as possible. The TranSystems team was responsible for the required environmental documents, preparation of a Project Report/Equivalent Document (PR/ED), geometric development, preparation of required base maps and plan sheets, structures plans, drainage and pump station design, stage construction and TMP, establishing right-of-way needs, and utility relocation.
