T. Barr, RLA Dan Davis, PE OV SANTg a, y 1 9L Ig'pR�S'i Ramona Boulevard is a secondary highway striped for two lanes in each direction, with an at -grade crossing of Union Pacific Railroad (UPRR) and Metro Link tracks between Cypress Avenue and Stewart Street. The AECOM project team provided the design and engineering services to grade- separate this crossing. AECOM was the prime consultant and was responsible for coordinating the design with several involved stakeholders including Caltrans, the City of El Monte, UPRR, Metrolink, ACE, the Gas Company, Sprint, Southern California Edison, the Los Angeles County Flood Control District, and Pacific Bell. The scope of work included preparation of Plans, Specifications, and Estimates (PS &E) for the project. AECOM also provided full construction management services. The construction work consisted of a new railroad bridge to accommodate two tracks for UPRR and Metro Link crossing at Ramona Boulevard, depressing east -west Ramona Boulevard to provide for the grade separation. The project also included design of retaining walls, new depressed and grade- separated sidewalks, storm drain pump station and drainage systems, landscaping, and major utility relocations (such as a 102 -inch RCP, fiber optic lines, telephone trunk lines, and water and gas main lines). Grade Separation The Orange County Transportation Authority (OCTA) selected AECOM to provide preliminary and final design services for a new railroad grade separation to replace the existing Orangethorpe Avenue /Burlington Northern Santa Fe (BNSF) Railroad at -grade crossing. The project calls for the design of an overcrossing of Orangethorpe Avenue with the BNSF tracks, with Orangethorpe Avenue being widened to a six -lane facility that includes a raised median island, six -foot wide sidewalks, and Class II bike lanes. Since Orangethorpe Avenue crosses the BNSF Railroad at an approximate 70- degree angle, AECOM developed an innovative approach using precast girders oriented perpendicular to the railroad tracks. This configuration lowers the roadway profile providing significant cost savings while maximizing the available right -of -way for BNSF. A temporary two -lane detour road is to be constructed, enabling Orangethorpe Avenue to remain open during construction Sign if icant coordination efforts are provided due to the numerous utilities to be 3 d A. P relocated, including a 36 -inch high p ressure gas line and overhead `.. electrical facilities. Structural efforts *ei,:' also include two bridges crossing a _ over flood control channels, and - - extensive MSE walls for the elevatedw. roadway. Additionally, AECOM is preparing a corridor -wide aesthetics guideline for OCTA for use in other - grade separations. ry Proposal for Project Study Report Equivalent and Conceptual Engineering Plans for Santa Ana Boulevard Grade Separation Project
