The subject of this Value Engineering study is the I-15 North Phase 4 project. This project is one is a series of project initially developed as a part of the I-15 N Corridor study. The Ph1 project has been completed. This phase included improvements to the I-15 from the Spaghetti Bowl to Craig. The Phase 2 project is from Craig to Speedway and will widen I-15 to 3 lanes and add Aux. lane between the ramp. Phase 2 is being advertized for construction (?). The Phase 3 project will is from Speedway to Apex and will include improvements similar to Ph 2.
The project we are her to discuss is the Phase 4 project, which is the construction of the I-15/CC215 system interchange. This project also includes conversion of the interim beltway facilities to freeway standards, a service interchange at I-15 and Tropical parkway and CC215 access from the local roadway system. The details of these improvement will be discussed in detail later in the presentation.

3. Planning Area North East Las Vegas ValleyFF
APEX INDUSTRIAL PARK
The I-15/CC215 Interchange is located in the City of North Las Vegas, in the north west corner of the Las Vegas Valley. It is surrounded by a wide variety of land uses and proposed developments which include:
Nellis AFB
Nevada Nat. Guard,
Proposed
Park Highlands and other residential developments to the west along the CC215
UNLV north Campus
CNLV Industrial Developments to the east of I-15 and in the Apex industrial park to the north.
The “FF” denotes the location of the recently approved Faraday Futures site.

5. Project Goals and Objectives
Provide Analysis to Identify…
“Most Desirable Interchange Layout”
Complete I-15/CC215
System Interchange
Address Local Access:
AADT
Range Rd 6,400
Tropical Pkwy 13,200
Centennial Pkwy 13,900
The goal of the current phase of the I-15 North Phase 4 project is to:
Identify the most desirable system interchange layout.
Address local access issues to Range Road, Tropical Parkway and CP.
This VE analysis is one of the last steps in the development of the “most desirable interchange layout”
Thus far we have analyzed two system interchange options, considered local access requirements and have developed a preferred alternative abased on this analysis.
