Future Integration 
Additional Garage            Roadway Improvements
Access Ramp                (6 lanes, raised profile) 
Busway & Stations



Support Anticipated Future Work  Build it Once 
7

Key Findings 
Additional lanes required to support Main
Garage access ramps 
Either private vehicles or commercial ground
transportation services 
Relocating Rental Car bus curb further north
improves curbside and busing operations 
Completed Pre-Design and Operational Analysis for Multiple Improvement Alternatives 
8

Key Findings 
Need to raise Arrivals roadway profile 
Supports anticipated SAMP Near-Term Project
roadway improvements (2-3 years after opening) 
Substantial construction impacts with
temporary roadways and relocation of major
utility systems 
Completed Pre-Design and Operational Analysis for Multiple Improvement Alternatives 
9

Recommended Alternative 
Relocate Rental
Car bus curb 
Widen to six lanes
Supports three                            (southbound) 
Garage access ramps 
Widen to four lanes
(Arrivals and Garage) 
Complete Tunnel                                  Raise roadway profile
Seismic Work                                       (forward compatible) 

Meets Main Terminal Access Requirements through 54 MAP and beyond

Project Risks 
SAMP Near-Term Environmental Review 
Design will proceed at risk and concurrent
with environmental review effort 
Construction authorization cannot be
pursued until environmental review is
completed 
Widen Arrivals Roadway is first SAMP Near-Term Project 
14

Project Risks 
Airport Utilities Master Plan 
Many facilities and systems located within
roadway corridor 
Phased design and construction approach to
accommodate likely scope changes 
Targeting Completion of Key Airport Utilities Master Plan Elements by Q4 2019
