This project consisted of preliminary and final design of capacity, safety, transit, and pedestrian improvements to the Rancho/Decatur dogleg intersections. Improvements facilitate two-lane through movements on Decatur Blvd, and include channelized dual right-turn lanes with signalized pedestrian crossings, triple left-turn lanes, bus turnouts, traffic signal upgrades with transit phases, and ADA upgrades. Improvements also included complete street treatments including detached sidewalk with amenity zone and street trees, and dual-directional perpendicular sidewalk ramps at intersection corners.
The project included development and evaluation of alternatives to improve transit stops and pedestrian crossing treatments at channelized skewed intersection. GCW developed special signal phasing to provide transit phases for exits from turnouts immediately downstream of dual-right improvements. Additionally, GCW developed innovative overhead guide signing complying with 2009 MUTCD down-arrow restrictions. The improvements also include PBS paving, raised median, curb/gutter, sidewalk, street lighting, and transitional improvements.
The project included topographic mapping, ROW, Record of Survey, and acquisition documents, hydraulic analyses/ drainage memo, specifications, and bid/construction support. Extensive coordination was also required with NDOT, CNLV, CCDOA, FAA (7460 permits), two adjacent capacity/transit improvement projects, an ITS improvement project, and with RTC/CLV on locating bus turnouts.
