Oil City Council last week voted to advertise for bids for the fabrication of replacement pontoons for the 30 year-old ice boom device on the Allegheny River.
Future bids will be accepted for the construction of the new ice boom itself, and for the demolition of the old device.
The city has received both federal and state grants for the project.
Planners are looking for 23 pontoons weighing about one-and-a-half tons apiece to replace the existing one-ton pontoons. Inspections have shown that the original steel cable linking the units can be reused. The entire device spans the river just above the confluence with Oil Creek, and is used to prevent ice jams at the junction.
