Engineering News-Record: Carolina Trunk Rehabilitation

The City of Portland’s Carolina Sewer Trunk Rehabilitation project is replacing a nearly 90-year-old sewer beneath one of the region’s most complex urban corridors, which includes challenging topography, residential neighborhoods, historic buried infrastructure and proximity to Interstate 5.

An unexpected underground challenge could have derailed the complex infrastructure project — but it didn’t. Discover Engineering News-Record’s coverage on how the project team adapted to deliver a multidisciplinary solution.
