Work on a pair of aging Nampa bridges previously set to begin this summer won't get under way until 2014, the Idaho Transportation Department announced.
The Union Pacific Railroad E. Lateral Canal bridge and the Northside Boulevard overpass at Interstate 84 were built in 1966. The replacement and repair of the structures over a six-month period will include replacing the bridge decks on the westbound UPRR bridge and the eastbound Northside bridge. The decks on the eastbound UPRR bridge and westbound Northside will be repaired and sealed with an epoxy overlay, and both structures will also get new paint.
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.
When work commences, the existing four lanes will remain open during work, ITD said, and speed-limit reductions and vehicle-width restrictions will be in place during the projects.
The Idaho Statesman will provide details about when the projects will begin when those details are finalized.
