Idaho 55 traffic will be restricted to one lane on Rainbow
Bridge beginning Monday, May 3 through Friday, May 7 while
crews conduct a bridge inspection.
The speed limit will be reduced to 25 mph while flaggers
direct traffic through the work zone.
The inspection is part of the Rainbow Bridge Restoration
project that will improve safety for travelers and preserve
and protect the historic structure. Over the years, exposure
to the elements has caused Rainbow Bridge to deteriorate.
The restoration project will include replacing the existing
ornate bridge rails, restoring the stone masonry approach
rails and retaining walls, repairing the deck, preventing
freeze-thaw and corrosion damage, and improving its resistance
Restoration of the arch, piers, and columns is scheduled
to begin during the summer of 2006. It is expected that traffic
flow will be maintained during this first phase of restoration.
