The project provides the complete full design and preparation of Stage II (30%), Stage III (60%), Stage IV (95%), Stage V (100%) Final Plans, Specifications & Construction Cost Estimate for the reconstruction and improvement of the existing standard diamond traffic interchange. The design of a standard diamond TI is preferred. The work will include: (1) Widening and reconstruction of Quartzsite Boulevard to add the additional lanes required to handle the forecasted traffic. (2) New overpass bridge structure over I-10. (3) Widening and reconstruction of the freeway ramps and ramp intersections with Quartzsite Boulevard. (4) Widening and reconstruction of the frontage road intersections and approaches with Main Street to the North and with Dome Rock Road/Kuehn Street to the South. (5) New modern fully actuated traffic control signalization at the two frontage road intersections and at the two ramp intersections. (6) New lighting to enhance travel safety within the TI area. (7) Incorporation of a sidewalk in the Quartzsite Blvd across I-10 and the two frontage roads. (8) Construct retaining walls where needed to eliminate the need for right of way acquisition on developed parcels. (9) Related grading, drainage and paving improvements. (10) Re-vegetation of any ground disturbance caused by the project with a native seed mix
