<br /> El Monte, California Ramona Boulevard is a secondary highway striped for two lanes in each direction,
<br /> . „gym with an at-grade crossing of Union Pacific Railroad (UPRR) and Metro Link tracks
<br /> °
<br /> between Cypress Avenue and Stewart Street. The AECOM project team provided
<br /> i...~~ ~
<br /> the design and engineering services tograde-separate this crossing.
<br /> °x'20 AECOM was the prime consultant and was responsible for coordinating the
<br /> - - - design with several involved stakeholders including Caltrans, the City of El Monte,
<br /> UPRR, Metrolink, ACE, the Gas Company, Sprint, Southern California Edison, the
<br /> ~ , Los Angeles Cou my Flood Control District, and Pacific Bell. The scope of work
<br /> included preparation of Plans, Specifications, and Estimates (PS&E) for the
<br /> project.
<br />
<br /> AECOM also provided full construction management services. The construction

<br /> Anaheim and Placentia, California The Orange County TransportationAothority (OCTA) selected AECOM to provide
<br /> preliminary and final design services for a new railroad grade separation to
<br />
<br /> o
<br /> , ~ replace the existing OrangethorpeAvenue/Burlington Northern Santa Fe (BNSF)
<br /> ~
<br /> Railroad at-grade crossing. The project calls for the design of an overcrossing
<br />
<br /> of Orangethorpe Avenue with the BNSF tracks, with Orangethorpe Avenue being
<br /> ~ ~ .
<br /> widened to a six-lane facility that includes a raised median island, six-foot wide
<br /> sidewalks, and Class II bike lanes. Since Orangethorpe Avenue crosses the BNSF
<br /> ° Railroad at an approximate 70-degree angle, AECOM developed an innovative
<br /> ~ ~ approach using precast girders oriented perpendiculartothe railroad tracks.This
<br /> m. configuration lowers the roadway profile providing significant cost savings while
<br /> maximizingthe available right-of-wayfor BNSF.
<br /> A temporary two-lane detour road is to be constructed, enabling Orangethorpe
