NW Thurman Street Bridge Project

1904 Rendering of proposed bridge

The City of Portland Bureau of Transportation (PBOT) is pleased to announce that the NW Thurman Street Bridge at NW 29th Avenue has been funded for a modernization and historic preservation project that will rebuild the bridge deck and superstructure.

The historic 108 year old bridge spans Lower Macleay Park near the entrance to Forest Park. The NW Thurman Street Bridge was built in 1905 as a streetcar bridge for the Lewis and Clark Centennial Exposition, commonly referred to as Portland’s World Fair. It has been repaired several times over the past 100 years. Serving residential traffic, TriMet buses, pedestrians and bicyclists, the bridge is in poor condition with a weight restriction that prohibits heavy traffic on it.

When the project is completed, the bridge weight restriction will be lifted. In addition to reconstructing the bridge deck, the project will replace wood stringers with steel members, preserve existing trusses, replace pedestrian walkway wood planks with skid-resistant aluminum, and aspire to reconstruct the pedestrian railing historically sympathetic to the original 1905 design.

PBOT has begun design engineering for the project and anticipates that construction will begin early 2014.

Funding for the project includes a $3.4 million grant from the Federal Highway Bridge Program and $390,000 of gas tax and parking revenues.
