<br /> Corona, California The City of Corona awarded AECOM the Auto Center grade separation project
<br /> over the BNSF railway line in Corona. The City of Corona is the lead agency. Auto
<br /> ~e
<br /> Center Drive runs north/south. Immediately north of the railroad, Auto Center
<br /> h p ~ is intersected by Railroad Street, which runs east/west, parallel to the railroad.
<br /> The West Corona Metrolink Station is located on the southeast quadrant of the
<br /> railroad crossing.
<br /> ~ ° ,I' AECOM is responsible for all aspects of the project, from start to bid, including
<br /> obtaining a PUC order to construct; developing and participating in the
<br /> negotiations with BNSF for the
<br /> `I"""' construction and maintenance

<br /> Montclair, California AECOM provided preliminary and final engineering design and construction

<br /> all aspects of the project, from start to constructioncompletion.Theproject
<br /> included an investigation of the most cost-effective alternative for separating
<br /> _
<br /> the grades, as well as environmental studies and clearance; right-of-way
<br /> ~
<br /> appraisals and acquisition; final design; plans, specifications, and cost estimates

<br /> for the construction of bridge, roadway, drainage, and grade separation related
