McCall's Lardo Bridge to close for approximately a month, starting in mid-October
BOISE – Starting in mid-October, Lardo Bridge will close for approximately one month while the existing bridge is demolished and the new bridge is slid into place, the Idaho Transportation Department announced.
Traffic will be detoured to Boydstun Street and Deinhard Lane.
The Idaho Transportation Department is replacing the 83-year old Lardo Bridge on the southwest shore of Payette Lake in McCall. Ralph L.Wadsworth and Lochner used ITD's conceptual design to complete the bridge design and build a new bridge that will accommodate one lane of traffic in each direction along with bicycle and pedestrian facilities on each side of the bridge.
The new bridge is being constructed north of the existing structure. By utilizing an accelerated construction technique called a lateral slide, the new bridge will eventually be slid into place after the old bridge is demolished. This method, the first used by ITD, reduces a full closure of the bridge by months.
Just last week, the final three 157-foot girders for the new bridge were set on the temporary structure. Three others, each weighing 197,000 lbs., were set the week prior.
Crews are currently driving permanent piles, installing rebar and constructing the bridge deck and overhangs.
The
construction/design contract is for $3.64 million.
