FIRST STREET PEDESTRIAN IMPROVEMENTS PS&E RFP NO.: 10-110 MISSION ROAD/HUNTINGTON DRIVE (SOTO BRIDGE REPLACEMENT), Los Angeles, California Soto Street Bridge over Mission Road and Huntington Drive was demolished and the roadways were realigned as part of the street improvements. Two new signalized intersections were installed along with Type It bike lanes throughout the project, ADA compliant sidewalks and ramps, and a landscaped median area along the newly built cul-de-sacs. Tetra Tech provided engineering support services during construction including RFIs, review of shop drawings, geotechnical support, responding to request for design changes, and preparing as-builts. The project team helped the City by investigating soil contamination levels and developing reports for handling and disposal of contaminated materials, redeveloping traffic control plans for increased work areas, and using Civil 3D software to understand and eliminate design issues. The design services included multiple phases of worksite traffic control, and temporary traffic signal, permanent signing and striping with continental crosswalks at all intersections and new bike lane facility, permanent traffic signal with interconnect and video fiber, street lighting, and several utilities such as power, gas, stormdrain, and communications utilities. SIXTH STREET PARK, ARTS, RIVER AND CONNECTIVITY (PARC), Los Angeles, California The City of Los Angeles held an international design contest for the replacement of the Sixth Street Viaduct. Demolition of the existing bridge began in early 2016 and the new bridge, known as the "Ribbon of Light," is expected to be constructed by 2020. The City of LA selected Tetra Tech, along with subconsultants Hargreaves Associates, and Michael Maltzan Architecture, to develop a unique landscape design and river improvements as part of the project. The team is providing schematic and final design, environmental documentation and permitting, public presentations, construction support services, and post -construction services for nearly 12 acres of recreational and open spaces beneath and around the new bridge. The project includes approximately X mile of improvements within the Los Angeles River, along with roadway improvements to South Santa Fe Ave., Mission Rd., Anderson St., and Clarence St. The City's goal is to make the landscape component under the new bridge a world class public space that will include an Arts Plaza, several performance stages, synthetic sports fields, river terracing, and bicycle and pedestrian pathways. 25K-30
