Glen Helen Parkway Grade Separation San Bernardino, California AECOM provided preliminary engineering for a project Report (PR) and Cliem, Environmental Document (ED) for the Glen Helen Parkway grade separation County of San Bernardino over both Union Pacific (UP) and Burlington Northern Santa Fe (BNSF) railroad Dept. of Public Works, 825 East Third tracks. Glen Helen parkway will be realigned and widened to four lanes to improve Street, Room 143 regional traffic circulation, improve access to the Hyundai Pavillion at Glen Helen, San Bernardino, CA 92415 improve fire and emergency service response time, and provide an all - weather crossing over the Cajon Wash. To support the regional park, the concert venue, Contact and the recreational potential of the area, the project includes an equestrian trail Chris Saed undercrossing and the pedestrian facilities will be ADA compliant. This project is 909.387.7877 strongly supported by the County Board of Supervisors. Year Completed Ongoing Construction Cost $40 million Design Cost $570,000 Team Members James Faber, PE Mohan Char, PE Albert Pan, PE The project tasks include development of realignment alternatives, bridge alternatives, evaluation of impacts to utilities and adjacent properties, developing engineering cost estimates, and assessing right -of -way impacts. Several major utility lines cross Glen Helen Parkway and accommodations or relocations of utilities need to be made to construct the proposed improvements. The Cajon Wash experiences severe flows from the Cajon Pass. The bridge must accommodate the flows and channel hydraulics will be studied to determine the appropriate level of scour protection and bridge foundations. Major bridge structures and retaining walls will be used to span the creek and railroads. It is anticipated that substantial protection from flood damage will --- - -�- be require construction of dikes and hard surfacing of embankments. Dillon Road Grade Separation Coachella, California AECOM provided preliminary and final engineering design for the Dillon Road grade separation project. AECOM was responsible for all aspects of the project, City f Coachella from start to bid, including obtaining a PUC order to construct; developing and y 1515 Sixth Street participating in the negotiations with UPRR for the construction and maintenance Coachella, CA 92236 agreement; environmental clearance; right -of -way; surveying; utility coordination; roadway; bridge; landscape; traffic; and geotechnical.
