ENGINEERING REVIEW

Due to proximity (this

leg of 99th St being

less that 150’ away)

99th St was added to

the Marine Ave signal

CONFLICT ADDING 99TH ST TO EXISTING If the east leg of 99th

was added to the

existing signal at the

west leg of 99th St,

creates conflict with

both sides of 99th St

going with the green

signal
