Replacements, repairs to pair of 47-year-old Nampa bridges slated for early summer
BOISE - Two bridge-rehabilitation projects in Nampa will be advertised to potential contractors this spring, with construction on the aging structures likely to begin in late June, the Idaho Transportation Department announced.
The Union Pacific Railroad (UPRR) E. Lateral Canal Bridge and the Northside Boulevard Overpass with I-84 (Exit 35) will be improved in this six-month project, finishing in December. Each of these structures was built in 1966.
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 with an epoxy overlay. The paint on the bridges also will be refreshed.

“The deck replacements will use an Accelerated Bridge Construction technique involving full-depth precast concrete deck panels that will be a first for Idaho,” said ITD Bridge Engineer Matt Farrar. “By doing this, we can reduce the time and impact to the traveling public, and extend the lives of these bridges.”

The existing four lanes will remain open during work.
Nighttime and weekend work is anticipated, particularly if needed to finish the job on time. During the later stages of the project, work will be prohibited during daylight hours (4 a.m. to 10 p.m.). Some on- and off-ramps will need to be closed during part of the project.
Speed-limit reductions and vehicle-width restrictions will be in place during the project.
