Welcome to Portland, Oregon-The Most Well
Connected City in the United States and the
Home of the Ugliest Building in the World*

* I work in this building

Tuesday, November 3, 2009

For purposes of discussion we will compare two pairs of
neighborhoods using their relative accessibility and connectivity to
illustrate the difﬁculty of building connected networks in the
modern urban setting.

The neighborhoods are:
Downtown
Gateway

NE 60th Ave LRT station area
NE 148th Ave. LRT station area

#1 Obstacle To Improving Transportation Networks

Sheer Enormity of the Problem
Increase in Intersection Density of Approximately six fold


Direct Outgrowth of Obstacle #1
Enormous Cost of Creating New Transportation Networks
To Create or Improve Transportation Networks in Three Areas
1. NE 60th Ave. LRT Station Area: $7 million
2. Gateway Regional Center: $70 million
3. NE 148th Ave. LRT Station Area: $21.2 million
$98.2 million
