Description

From Wikipedia, the free encyclopedia:
The Interstate Bridge (also Columbia River Interstate Bridge, I-5 Bridge, Portland-Vancouver Interstate Bridge, Vancouver-Portland Bridge) is a pair of nearly identical steel vertical-lift, "Parker type" through-truss bridges

Carries: 6 lanes of I‑5
Crosses:  Columbia River
Design:  Dual truss with vertical lifts
Total length:  3,538 ft (1,078 m)
Width: Northbound span 38 ft (12 m); southbound span 39 ft (12 m)
Height: Approx. 230 ft (70 m)
Longest span: 531 ft (161.8 m)
Clearance below: 72 ft (21.9 m) at highest fixed span; 176 ft (53.6 m) at open lift span

The bridge opened to traffic in 1917 as a single bridge carrying two-way traffic. A second, twin bridge opened in 1958 with each bridge carrying one-way traffic. The original 1917 structure is the northbound bridge. As of 2006, the bridge pair handles around 130,000 vehicles daily. The green structure, which is over 3,500 feet (1,067 m) long, carries traffic over three northbound lanes and three southbound lanes. It was added to the National Register of Historic Places in 1982, as the "Portland–Vancouver Highway Bridge"
