The existing four-lane roadway was widened to six-lanes. Full design services were provided, including roadway and drainage design, permitting, design of six signals, signing and marking, and lighting throughout the corridor. The existing pedestrian facilities within the corridor were expanded to provide a multiuse trail. This project also included major utility coordination of potable water mains, raw water mains, force mains, gas mains, power lines and cable television. A right-turn bypass lane was constructed to improve traffic flows through the highly congested Golden Gate Parkway and Goodlette-Frank Road intersection. The drainage design included construction of 2.75 mile drainage pipe to intercept pavement runoff prior to entering a major drainage ditch. The intercepted pavement runoff was treated and attenuated in two ponds. The design significantly reduced localized neighborhood flooding. Roadway, lighting, structural, and signalization plans were prepared. Utility plans were prepared for the relocation of water mains, raw water mains and force mains. The design schedule was highly accelerated when American was directed to prepare bid-ready plans in three weeks with the plans at just 75% complete. Multiple public involvement meetings were held to solicit public comment and address access management concerns. American reviewed and evaluated existing traffic counts at seven intersections to support closing of median openings and removal of a traffic signal.
