Big Pipe Portal

From Oregon Hikers Field Guide

Big Pipe Portal, McCarthy Promenade (bobcat)


The Big Pipe Portal sculpture, dedicated in 2009 and created by the rhiza A + D firm, symbolizes Portland’s costliest infrastructure project at $1.4 billion. The Big Pipe runs under the Willamette and was designed to carry larger volumes of sewerage in order to prevent the frequent overflows into the river. The sculpture is the same diameter as the pipe itself. Just to the east, you can see the Swan Island Pump Station complex.

The acreage in this area is set to be extensively developed in the coming years, so expect a lot of construction fencing and noise!
