Geography challenge

Geography funnels traffic from several key corridors onto I-5.

ISSUE 1

SLIDE 2

Less redundancy

Northern OC has a dense network of roadways for traffic to shift to during unexpected incidents. Southern OC has a limited network, which constrains options during incidents.

ISSUE 2

SLIDE 3

Emergency access

I-5 remains the main emergency access linkage to southern Orange County. Additional redundancy would be useful for emergency services.

Rail constraint

The rail system is limited to single track in this area.
