orth Beltway, Tenaya to Decatur

This project consisted of final design of 4-lane mainline with auxiliary lanes, overpass at Bradley and interchanges at Jones and Decatur. The project length was approximately 3 miles and included concrete paving, bridge structures at Jones, Bradley and Decatur, regional and roadway drainage facilities, signing, striping, traffic signals at Jones and Decatur, roadway lighting studies, lighting (arterial, high mast, underdeck, and overhead guide signs), ITS conduit/pull boxes and improvements on Jones, Bradley, and Decatur to tie into to the existing improvements. The traffic related design work included 4 signalized ramp terminal intersections, special transition designs, guide sign legend design, 13 overhead sign support details, intersection channelization, turn path analyses, and cat-track details. The drainage improvements included over 16,500 lf of concrete-lined channel ranging from 32-ft by 10-ft to 50-ft by 10-ft. GCW provided plans for relocation of 18-inch sewer for construction of drainage infrastructure at Jones and 215; and installation of 24- and 36-inch casing at intersection of Jones and 215. The project also included the design of soundwalls, MSE walls, retaining walls, and NB US 95 off ramp to CC 215 East. The project required extensive coordination with CCPW, CLV, CNLV, CCRFCD, NV Energy, and NDOT. GCW’s survey department provided project control, aerial mapping coordination and control, design engineering as-built surveys, easement descriptions and exhibits, filing Record of Survey, and preparation of project control plan.
