Northside Boulevard Underpass & UPRR E. Lateral Canal Bridge, Nampa
Nampa Bridge

Project Key Number: 12866/12867

Project Description:

Reconstruction of the aging Union Pacific Railroad (UPRR) E. Lateral Canal Bridge and the Northside Boulevard Overpass with Interstate 84 at Exit 35 is underway.

The bridge decks on the westbound UPRR bridge and the eastbound Northside structure will be replaced, while decks on the eastbound UPRR bridge and westbound Northside will be repaired and sealed. Both bridges were built in 1966.

The Northside interchange is ranked 8th in the state in traffic volume, carrying 80,000 vehicles per day.

Construction Schedule:

Work began June 2, 2014. The Idaho Transportation Department expects this to be a six-month project, finishing in December.

Traffic Impacts:

Northside Boulevard is reduced from five lanes to three, one in each direction with a center turn lane, through the project area. This configuration will remain in place through mid-July. Intermittent nighttime lane closures are occurring on I-84 through the construction zone (mileposts 34.9-35.2), between 9 p.m. and 5 a.m.
