A public meeting to discuss upcoming bridge work in Milltown is scheduled for Monday, July 17, 2006 from 6:30 - 8:30 pm at the Bonner School Gym.

Spanning the Blackfoot River in just a short stretch are five bridges – one belonging to Montana Rail Link, two I-90 bridges, the Highway 200 and Missoula County’s pedestrian bridge. Before the Milltown Dam can be removed in 2008, those bridges – built to stand in slack water – will have to be upgraded or replaced to withstand the restored flows of the Blackfoot River.

To do that, the bridge piers and abutments must be made strong enough to handle the additional scour and erosion of the river bed and banks, and the bridge abutments must be strengthened to account for temporary bank instability as the water table is permanently lowered.

The EPA, US Army Corps of Engineers and its contractors will present information about the work planned for the I-90, Hwy 200 and pedestrian bridges. Representatives from Montana Rail Link have been invited to participate and discuss its plans for the railroad bridge.
